Organization, Consolidation and Presentation of Financial Statements [Abstract]
GENERAL	NOTE 1:- GENERAL a. SolarEdge Technologies, Inc. (the “Company”) and its subsidiaries design, develop, and sell an intelligent inverter The Company and its subsidiaries sell products worldwide through large distributors, electrical equipment wholesalers, as well as directly to large solar installers and engineering, procurement and construction firms. b. The Company has expanded its activity to other areas of smart energy technology organically and through c. Recently issued and adopted pronouncements: In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (ASU 2020-06), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. This guidance also eliminates the treasury stock method to calculate diluted earnings per share for convertible instruments and requires the use of the if-converted method. ASU 2020-06 will be effective for fiscal years beginning after December 15, 2021, with early adoption permitted. Effective January 1, 2021, the Company early adopted ASU 2020-06 using the modified retrospective approach. Adoption of the new standard resulted in an increase of retained earnings in an amount of $2,884, a decrease of an additional paid-in capital in an amount of $36,336, an increase of convertible senior notes, net, in an amount of $45,282 and a decrease of deferred tax liabilities, net, in an amount of $11,830. Interest expense recognized in future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost. In January 2020, the FASB issued ASU 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815), which clarifies the interaction between the accounting for equity securities in Topic 321, the accounting for equity method investments in Topic 323, and the accounting for certain forward contracts and purchased options in Topic 815. The guidance is effective for interim and annual periods beginning after December 15, 2020. Effective January 1, 2021, the Company adopted this standard on a prospective basis. The impact of adoption of this standard on the Company’s consolidated financial statements was immaterial. F - 10 SOLAREDGE TECHNOLOGIES, INC. AND ITS SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) U.S. dollars in thousands (except share and per share data) NOTE 1:- GENERAL (Cont.) d. Basis of Presentation: The unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). In management’s opinion, the unaudited condensed consolidated financial statements reflect all adjustments of a normal recurring nature that are necessary for a fair presentation of the results for the interim periods presented. The Company’s interim period results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. The significant accounting policies applied in the annual consolidated financial statements of the Company as of December 31, 2020, contained in the Company’s Annual Report on Form 10-K/A filed with the SEC on February 19, 2021, have been applied consistently in these unaudited interim condensed consolidated financial statements, except for the adoption of ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (Topic 470) (see Note 7). e. Use of estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related disclosures in the accompanying notes. The duration, scope and effects of the ongoing COVID-19 pandemic, government and other third party responses to it, and the related macroeconomic effects, including to the Company’s business and the business of the Company’s suppliers and customers are uncertain, rapidly changing and difficult to predict. As a result, the Company’s accounting estimates and assumptions may change over time in response to this evolving situation. Such changes could result in future impairments of goodwill, intangibles, long-lived assets, inventories, incremental credit losses on receivables and AFS debt securities, or an increase in the Company’s insurance liabilities as of the time of a relevant measurement event. f. Concentrations of supply risks: The Company depends on two contract manufacturers and several limited or single source component suppliers. Reliance on these vendors makes the Company vulnerable to possible capacity constraints and reduced control over component availability, delivery schedules, manufacturing yields, and costs. As of March 31, 2021, and December 31, 2020, two contract manufacturers collectively accounted for 37.9% and 48.5% of the Company’s total trade payables, net, respectively. During 2020, the Company started production in its manufacturing facility in the North of Israel, “Sella 1”. The Company expects manufacturing capacity to continue to increase until the second quarter of 2021 when Sella 1 is expected to reach full manufacturing capacity. g. Certain prior period amounts have been reclassified to conform to the current period presentation.

Equity Method Investments and Joint Ventures [Abstract]
INVESTMENT IN PRIVETLY-HELD COMPANIES	NOTE 4:- INVESTMENT IN PRIVETLY-HELD COMPANIES On January 31, 2021, the Company completed an investment of $ 11,643 in the preferred stock of AutoGrid Systems, INC ("AutoGrid"), a privately held company without readily determinable fair values. On February 1, 2021, the Company signed on a preferred stock purchase agreement for an additional investment of $ 5,000 in AutoGrid's preferred stock ("second investment"). As of March 31, 2021, the final closing of the second investment had not yet occurred. On April 28, the Company completed the second investment. Under ASU 2016-01 equity investments without readily determinable fair value include ownership rights that either (i) do not meet the definition of in-substance common stock or (ii) do not provide the Company with control or significant influence. The Company adjusts the carrying value of its non-marketable equity securities to fair value upon observable transactions for identical or similar investments of the same issuer or upon impairment. All gains and losses on non-marketable equity securities, realized and unrealized, are recognized in financial expenses, net. The Company accounted for the AutoGrid investment as an equity investment that do not have readily determinable fair values. As such, the Company’s non-marketable equity securities had a carrying value of $11,643 as of March 31, 2021. The maximum loss the Company can incur for its investments is their carrying value. Investment in privately-held companies are included within other long-term assets on the consolidated balance sheets. The Company periodically evaluates the carrying value of the investments in privately-held companies when events and circumstances indicate that the carrying amount of the investment may not be recovered. These investments include the Company’s holdings in privately-held companies that are not traded and therefore not supported with observable market prices. The Company may determine the fair value by reviewing equity valuation reports, current financial results, long-term plans of the privately-held companies, the amount of cash that the privately-held companies have on-hand, the ability to obtain additional financing and overall market conditions in which the privately-held companies operate or based on the price observed from the most recent completed financing. No impairment or other adjustments related to observable price changes in orderly transactions for identical or similar investments were identified for the three months ended March 31, 2021.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 5:- FAIR VALUE MEASUREMENTS In accordance with ASC 820, the Company measures its cash equivalents and marketable securities, at fair value using the market approach valuation technique. Cash equivalents and marketable securities are classified within Level 1 and Level 2, respectively, because these assets are valued using quoted market prices or alternative pricing sources and models utilizing market observable inputs. Foreign currency derivative contracts are classified within the Level 2 value hierarchy, as the valuation inputs are based on quoted prices and market observable data of similar instruments. The following table sets forth the Company’s assets that were measured at fair value as of March 31, 2021 and December 31, 2020 by level within the fair value hierarchy: Fair value measurements as of Fair Value March 31, December 31, Description Hierarchy 2021 2020 Measured at fair value on a recurring basis: Assets: Cash equivalents: Money market mutual funds Level 1 $ 292,417 $ 480,673 Derivative instruments asset: Options and forward contracts not designated as hedging instruments   Level 2 $ 449 3,786 Short-term marketable securities: Corporate bonds Level 2 $ 134,603 $ 142,276 Governmental bonds Level 2 $ 4,476 $ 1,411 Long-term marketable securities: Corporate bonds Level 2 $ 284,087 $ 142,552 Governmental bonds Level 2 $ 10,741 $ 4,882 Liabilities Derivative instruments liability: Options and forward contracts designated as hedging instruments   Level 2 $ (146 ) $ - Options and forward contracts not designated as hedging instruments   Level 2 $ - (5,819 )

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	NOTE 6:- DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES The Company accounts for derivatives and hedging based on ASC 815 (“Derivatives and Hedging”). ASC 815 requires the Company to recognize all derivatives on the balance sheet at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. To protect against the increase in value of forecasted foreign currency cash flows resulting from salary denominated in the Israeli currency, the New Israeli Shekels (“NIS”), during the three months March 31, 2021, the Company instituted a foreign currency cash flow hedging program. The Company hedges portions of the anticipated payroll denominated in NIS for a period of one to nine months with hedging contracts. Accordingly, when the dollar strengthens against the NIS, the decline in present value of future foreign currency expenses is offset by losses in the fair value of the hedging contracts. Conversely, when the dollar weakens, the increase in the present value of future foreign currency cash flows is offset by gains in the fair value of the hedging contracts. These hedging contracts are designated as cash flow hedges, as defined by ASC 815 and are all effective hedges. As of March 31, 2021, the Company entered into forward contracts to sell U.S. dollars for NIS in the amount of $42,000. In addition to the above-mentioned cash flow hedges transactions, the Company also entered into derivative instrument arrangements to hedge the Company’s exposure to currencies other than the U.S. dollar. These derivative instruments are not designated as cash flow hedges, as defined by ASC 815, and therefore all gains and losses, resulting from fair value remeasurement, were recorded immediately in the statement of income, as financial expenses, net. As of March 31, 2021, the Company entered into forward contracts and put and call options to sell Australian dollars (“AUD”) for U.S. dollars in the amount of AUD 12 million and AUD 30 million, respectively. As of March 31, 2021, the Company entered into forward contracts and put and call options to sell Euro (“EUR”) for U.S. dollars in the amount of EUR 39 million and EUR 57 million, respectively. As of March 31, 2021, the Company entered into forward contracts to sell U.S. dollars for South Korean Won in the amount of $28,000. The fair value of derivative assets as of March 31, 2021 and December 31, 2020, was $449 and $3,786, which was recorded in prepaid expenses and other current assets in the consolidated balance sheets, respectively. The fair value of derivative liabilities as of March 31, 2021 and December 31, 2020, was $146 and $5,819, which was recorded in accrued expenses and other current liabilities in the consolidated balance sheets, respectively. For the three months ended March 31, 2021, the Company recorded a gain in the amount of $3,536 in financial expense, net, related to the derivative instruments not designated as cash flow hedges. The Company had no gains or losses related to derivative instruments during the three months ended March 31, 2020. For the three months ended March 31, 2021 and 2020, the Company recorded unrealized gain (loss) in the amount of $(128) and $538, net of tax effect, respectively, in “accumulated other comprehensive loss” related to the derivative assets designated as hedging instruments.

The Notes do not bear regular interest and mature on September 15, 2025, unless earlier repurchased or converted in accordance with their terms. The Notes are general senior unsecured obligations of the Company. Holders may convert their Notes prior to the close of business on the business day immediately preceding June 15, 2025 in multiples of $1,000 principal amount, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2020 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five-business-day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the Notes for each trading day of that five consecutive trading day period was less than 98% of the product of the last reported sale price of the common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events as described in the Indenture. In addition, holders may convert their Notes, in multiples of $1,000 principal amount, at their option at any time beginning on or after June 15, 2025, and prior to the close of business on the second scheduled trading day immediately preceding the stated maturity date of the Notes, without regard to the foregoing circumstances. The initial conversion rate for the Notes was 3.5997 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $277.80 per share of common stock, subject to adjustment upon the occurrence of certain specified events as set forth in the Indenture. Upon conversion, the Company may choose to pay or deliver, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock. In addition, upon the occurrence of a fundamental change (as defined in the Indenture), holders of the Notes may require the Company to repurchase all or a portion of their Notes, in multiples of $1,000 principal amount, at a repurchase price of 100% of the principal amount of the Notes, plus any accrued and unpaid special interest, if any, to, but excluding, the repurchase date. If certain fundamental changes referred to as make-whole fundamental changes occur, the conversion rate for the Notes may be increased. The Convertible Senior Notes consisted of the following as of March 31, 2021 and December 31, 2020: As of As of March 31, 2021 December 31, 2020 Liability: Principal $ 632,500 $ 632,500 Unamortized debt discount - (46,353 ) Unamortized issuance costs (13,143 ) (12,797 ) Net carrying amount $ 619,357 $ 573,350 Equity component: Amount allocated to conversion option $ - $ 48,834 Deferred taxes liability, net - (11,368 ) Allocated issuance costs - (1,130 ) Equity component, net $ - $ 36,336 F - 16 SOLAREDGE TECHNOLOGIES, INC. AND ITS SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) U.S. dollars in thousands (except share and per share data) NOTE 7:- CONVERTIBLE SENIOR NOTES (Cont.) As of March 31, 2021, the debt issuance costs of the Notes will be amortized over the remaining term of approximately 4.5 years. Prior to January 1, 2021, the Company separated the Notes into liability and equity components. On issuance, the carrying amount of the equity components was recorded as a debt discount and subsequently amortized to interest expense. Effective January 1, 2021, the Company early adopted ASU 2020-06 using the modified retrospective approach. The Notes are accounted for as a single liability measured at its amortized cost, as no other embedded features require bifurcation and recognition as derivatives. Adoption of the new standard resulted in an increase of retained earnings in an amount of $2,884, a decrease of an additional paid-in capital in an amount of $36,336, an increase of convertible senior notes, net, in an amount of $45,282 and a decrease of deferred tax liabilities, net, in an amount of $11,830. The annual effective interest rate of the Notes following the adoption of ASU 2020-06 is 0.47%. Interest expense related to the amortization of debt issuance costs was $724 for the three months ended March 31, 2021. As of March 31, 2021, the estimated fair value of the Notes, which the Company has classified as Level 2 financial instruments, is $812,294. The estimated fair value was determined based on the quoted bid price of the Notes in an over-the-counter market on the last trading day of the reporting period. As of March 31, 2021, the if-converted value of the Notes exceeded the principal amount by $179,794.

COMMITMENTS AND CONTINGENT LIABILITIES	NOTE 9:- COMMITMENTS AND CONTINGENT LIABILITIES a. Guarantees: As of March 31, 2021, contingent liabilities exist regarding guarantees in the amounts of $18,373, $2,712 and $476 in respect of bank loans, office rent lease agreements and other transactions, respectively. b. Contractual purchase obligations: The Company has contractual obligations to purchase goods and raw materials. These contractual purchase obligations relate to inventories held by contract manufacturers and purchase orders initiated by the contract manufacturers, which cannot be canceled without penalty. The Company utilizes third parties to manufacture its products. In addition, the Company acquires raw materials or other goods and services, including product components, by issuing authorizations to its suppliers to purchase materials based on its projected demand and manufacturing needs. As of March 31, 2021, the Company had non-cancelable purchase obligations totaling approximately $699,325 out of which the Company recorded a provision for loss in the amount of $5,009. As of March 31, 2021, the Company had contractual obligations for capital expenditures totaling approximately $84,811. These commitments reflect purchases of automated assembly lines and other machinery related to the Company’s manufacturing process as well as capital expenditures associated with the construction of Sella 2, the Company’s planned second lithium-ion cell and battery factory in Korea. c. Legal claims: From time to time, the Company may be involved in various claims and legal proceedings. The Company reviews the status of each matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated, the Company accrues a liability for the estimated loss. These accruals are reviewed at least quarterly and adjusted to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular matter. In September 2018, the Company’s German subsidiary, SolarEdge Technologies GmbH received a complaint filed by competitor SMA Solar Technology AG (“SMA”). The complaint, filed in the District Court Düsseldorf, Germany, alleged that the Company’s 12.5kW - 27.6kW inverters infringe two of the plaintiff’s patents. In its complaint, SMA asserted a value in dispute of EUR 5.5 million (approximately $6,455) for both patents. The Company challenged the validity of both patents. With respect to one of the claims, in October 2020, the German Patent Court rendered the SMA patent invalid, this invalidity has been appealed by SMA. With respect to the other claim, in November 2019, the first instance court stayed the infringement proceedings since it considered it to be highly likely that the second SMA patent would also be rendered invalid. The Company believes that it has meritorious defenses to the claims asserted and intends to vigorously defend against the remaining lawsuit. In May 2019, the Company’s two Chinese subsidiaries and its equipment manufacturer in China were served with three lawsuits by Huawei Technologies Co., Ltd., a Chinese entity (“Huawei”).

The lawsuits, filed in the Guangzhou intellectual property court, alleged infringement of three patents and asked for an injunction of manufacture, use, sale and offer for sale, and damage awards. A first-instance judgment was issued on August 7, 2020 ordering the three defendants to collectively pay damages in the amount of approximately Chinese Yuan (“CNY”) 10.5 million (approximately $1,607), including court fees, with respect of one of the patents. The Company has filed an appeal with the Supreme People’s Court of China. The first instance court’s judgement is not effective or enforceable pending the appeal. In addition, in January 2021, Huawei filed a motion to increase its claimed monetary damages to CNY 50.5 million (approximately $7,700) and for a preliminary injunction with respect to the second lawsuit. In February 2021, a preliminary injunction was rendered by the Guangzhou intellectual property court with respect to such second lawsuit and applying to seven inverter models. In line with the court’s mandate, the Company took immediate action to make software changes to meet the court order and also appealed the decision. In addition, in February 22, 2021 a first-instance judgment was issued ordering the three defendants to collectively pay damages in the amount of CNY 50.5 million (approximately $7,700), including court fees, with respect to the second patent. The Company appealed this judgement with the Supreme People’s Court. The first instance court’s judgement is not effective or enforceable pending the appeal. The Company believes that it has meritorious defenses to the claims asserted by Huawei. In December 2019, the Company received a lawsuit filed by a former consultant of the Company and its Israeli subsidiary in the amount of 25.5 million NIS (approximately $7,648) claiming damages caused relating to a terminated consulting agreement and stock options therein. The Company believes it has meritorious defenses to the claims asserted and intends to vigorously defend against this lawsuit. As of March 31, 2021, accrued amounts for legal claims of $9,265, were recorded in accrued expenses and other current liabilities.

Income Taxes
INCOME TAXES	NOTE 13:- INCOME TAXES The effective tax rate for the three months ended March 31, 2021 and 2020 were 20.9%, and 17.4% respectively. The increase in the effective tax rate in the current year is primarily due to presence of a full valuation allowance in various jurisdictions and different allocation of income among the Company’s US, Israel, and foreign subsidiaries. The Company’s effective tax rate was lower than the U.S. federal statutory rate for the three months ended March 31, 2021, due to earnings taxed at lower rates in foreign jurisdictions and tax benefits relating to stock-based compensation, which were primarily offset by full valuation allowance in various jurisdictions and GILTI tax. As of March 31, 2021, and December 31, 2020, unrecognized tax benefits were $10,630 and $10,564, respectively. If recognized, such benefits would favorably affect the Company’s effective tax rate. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income taxes. The total amount of penalties and interest were $152 and $127 as of March 31, 2021 and December 31, 2020, respectively. It is reasonably possible that the Company’s gross unrecognized tax benefits will decrease by up to $8,937 in the next 12 months, primarily due to the lapse of the statute of limitations. These adjustments, if recognized, would positively impact the Company’s effective tax rate, and would be recognized as additional tax benefits.

SEGMENT INFORMATION	NOTE 14:- SEGMENT INFORMATION a. Segment Information: The Company operates in five different operating segments: Solar, Critical Power, Energy Storage, e-Mobility and Automation Machines. The Company's Chief Executive Officer, who is the chief operating decision maker (“CODM”) , makes resource allocation decisions and assesses performance based on financial information presented on a consolidated basis, accompanied by disaggregated information about revenues and contributed profit by the operating segments. Segment profit is comprised of gross profit for the segment less operating expenses that do not include amortization, stock based compensation expenses and certain other items. The Company manages its assets on a group basis, not by segments, as many of its assets are shared or commingled. The Company’s CODM does not regularly review asset information by segments and, therefore, the Company does not report asset information by segment. The Company identified one operating segment as reportable – the Solar segment. The other operating segments are insignificant individually and therefore their results are presented together under “All other”. The Solar segment includes the design, development, manufacturing, and sales of an intelligent inverter solution designed to maximize power generation at the individual PV module level. The solution consists mainly of the Company’s power optimizers, inverters and cloud-based monitoring platform. The “All other” category includes the design, development, manufacturing and sales of UPS products, energy storage products, e-Mobility products and automated machines. The Company does not allocate to its operating segments revenue recognized due to advance payments received for performance obligations that extend for a period greater than one year (“financing component”), related to Accounting Standard Codification 606, “Revenue from Contracts with Customers” (ASC 606).

Convertible Senior Notes due 2025 [Member]
Debt Instrument [Line Items]
Debt conversion description	On September 25, 2020, the Company sold $632,500 aggregate principal amount of its 0.00% convertible senior notes due 2025 (the “Notes”). The Notes were sold pursuant to an indenture, dated September 25, 2020 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”). The Notes do not bear regular interest and mature on September 15, 2025, unless earlier repurchased or converted in accordance with their terms. The Notes are general senior unsecured obligations of the Company. Holders may convert their Notes prior to the close of business on the business day immediately preceding June 15, 2025 in multiples of $1,000 principal amount, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2020 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five-business-day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the Notes for each trading day of that five consecutive trading day period was less than 98% of the product of the last reported sale price of the common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events as described in the Indenture. In addition, holders may convert their Notes, in multiples of $1,000 principal amount, at their option at any time beginning on or after June 15, 2025, and prior to the close of business on the second scheduled trading day immediately preceding the stated maturity date of the Notes, without regard to the foregoing circumstances. The initial conversion rate for the Notes was 3.5997 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $277.80 per share of common stock, subject to adjustment upon the occurrence of certain specified events as set forth in the Indenture.
