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 their intelligent inverter solution products worldwide through large distributors and electrical equipment wholesalers to smaller solar installers as, well as directly to large solar installers and engineering, procurement and construction firms (“EPCs”). The Company has expanded its activity to other areas of smart energy technology through acquisitions. The Company now offers energy solutions which include lithium-ion cells, batteries and energy storage systems (“Energy Storage”), electric vehicle, or EV components and charging capabilities (“e-Mobility”), uninterrupted power supply solutions (“UPS”), as well as the manufacture of automated machines for industries (“Automation Machines”). b. Recent accounting pronouncements not yet adopted: In August 2020, the FASB issued ASU No. 2020-06, 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 in an entity’s own equity. Among other changes, ASU 2020-06 removes from U.S. GAAP the liability and equity separation model for convertible instruments with a cash conversion feature, and as a result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. Among other potential impacts, this change is expected to reduce reported interest expense, increase reported net income, and result in a reclassification of certain conversion feature balance sheet amounts from stockholders’ equity to liabilities as it relates to the Company’s convertible senior notes. Additionally, ASU 2020-06 requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share (EPS), which is consistent with the Company’s accounting treatment under the current standard. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020, and can be adopted on either a fully retrospective or a modified retrospective basis. The Company is currently evaluating the timing, method of adoption and overall impact of this standard on its consolidated financial statements. F - 12 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.) c. Recently issued and adopted pronouncements: In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (ASU) No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The FASB subsequently issued amendments to ASU 2016-13, which have the same effective date and transition date of January 1, 2020. This standard requires entities to estimate an expected lifetime credit loss on financial assets ranging from short-term trade accounts receivable to long-term financings and report credit losses using an expected losses model rather than the incurred losses model that was previously used, and establishes additional disclosures related to credit risks. For available-for-sale (“AFS”) debt securities with unrealized losses, the standard eliminates the concept of other-than-temporary impairments and requires allowances to be recorded instead of reducing the amortized cost of the investment. This standard limits the amount of credit losses to be recognized for AFS debt securities to the amount by which carrying value exceeds fair value and requires the reversal of previously recognized credit losses if fair value increases. The Company adopted Topic 326 effective January 1, 2020, based on the composition of the Company’s trade receivables, investment portfolio and other financial assets, current economic conditions and historical credit loss activity. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. The condensed consolidated financial statements for the nine months ended September 30, 2020 are presented under the new standard, while comparative periods presented are not adjusted and continue to be reported in accordance with the Company’s historical accounting policy (see Note 7). 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, 2019, contained in the Company’s Annual Report on Form 10-K filed with the SEC on February 27, 2020, have been applied consistently in these unaudited interim condensed consolidated financial statements, except for ASC 815 - Derivatives and Hedging (see Note 6), the adoption of ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) (see Note 7) and ASC 470-20 "Debt with Conversion and Other Options" (see Note 8). e. 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.

In September 2020 the Company has commenced the production ramp up of its manufacturing facility in the North of Israel, “Sella 1”. The Company expects ramp up to continue until the second quarter of 2021. f. Use of estimates: The preparation of financial statements in conformity with U.S. 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. g.

FAIR VALUE MEASUREMENTS	NOTE 5:- FAIR VALUE MEASUREMENTS In accordance with ASC 820, the Company measures its cash equivalents, foreign currency derivative contracts, and marketable securities, at fair value using the market approach valuation technique. Cash equivalents and marketable securities are classified within Level 1 or Level 2 based on whether 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 September 30, 2020 and December 31, 2019, by level within the fair value hierarchy: Fair value measurements as of Fair Value September 30, December 31, Description Hierarchy 2020 2019 Assets: Cash equivalents: Money market mutual funds Level 1 $ 721,088 $ 527 Derivative instruments asset: Options and forward contracts not designated as hedging  instruments Level 2 $ 780 $ - Short-term marketable securities: Corporate bonds Level 2 $ 109,173 $ 91,845 Governmental bonds Level 2 $ 1,412 $ - Long-term marketable securities: Corporate bonds Level 2 $ 21,003 $ 117,778 Governmental bonds Level 2 $ - $ 1,398 Liabilities: Derivative instruments liability: Options and forward contracts not designated as hedging instruments Level 2 $ (1,119 ) $ -

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 nine months ended September 30, 2020, the Company instituted a foreign currency cash flow hedging program whereby portions of the anticipated payroll denominated in NIS for a period of one to six 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 September 30, 2020, the Company had no derivative instruments that were designated as cash flow hedges. 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 a financial expense (income), net. As of September 30, 2020, the Company entered into forward contracts to sell Australian dollars (“AUD”) for U.S. dollars in the amount of AUD 7.5 million. As of September 30, 2020, the Company entered into put and call options to sell Euro ("EUR") for U.S. dollars in the amount of EUR 45 million. As of September 30, 2020, the Company entered into put and call options to sell U.S. dollars for South Korean Won in the amount of USD 48.6 million. The fair value of derivative assets as of September 30, 2020, was $780, which was recorded in prepaid expenses and other current assets in the Condensed Consolidated Balance Sheets. The fair value of derivative liabilities as of September 30, 2020, was $1,119, which was recorded in accrued expenses and other current liabilities in the Condensed Consolidated Balance Sheets. As of December 31, 2019 and for the year then ended, the Company had no derivative instruments (see Note 5). For the three and nine months ended September 30, 2020, the Company recorded a loss in the amount of $1,450 and $959, respectively, in “financial income, net” related to the derivative assets not designated as hedging instruments.

CREDIT LOSSES

Receivables [Abstract]
CREDIT LOSSES	NOTE 7:- CREDIT LOSSES Effective January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, prospectively. This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial instruments, including trade receivables. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements. The amendment requires entities to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivables that are current or not yet due, which were not considered under the previous accounting guidance. As stated above, the Company did not record a noncash cumulative effect adjustment on the opening consolidated balance sheet as of January 1, 2020, due to immateriality. The Company is exposed to credit losses primarily through sales of products. The Company’s expected loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the status of customers' trade accounts receivables. Due to the short-term nature of such receivables, the estimate of amount of accounts receivable that may not be collected is based on aging of the accounts receivable balances, the financial condition of customers and the Company’s historical experience with similar customers. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible. The Company considered the current and expected future economic and market conditions surrounding the COVID-19 pandemic and determined that the estimate of credit losses was not significantly impacted as of September 30, 2020. Estimates are used to determine the allowance. The allowance is based on assessment of anticipated payment and other historical, current and future information that is reasonably available. The following table provides a roll-forward of the allowance for credit losses that is deducted from the amortized cost basis of trade receivables to present the net amount expected to be collected: Nine months ended September 30, 2020 Balance, at beginning of period $ 2,473 Provision for expected credit losses 4,595 Amounts written off charged against the allowance and others (378 ) Balance, at end of period $ 6,690

Debt Disclosure [Abstract]
CONVERTIBLE SENIOR NOTES	NOTE 8:- CONVERTIBLE SENIOR NOTES 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. 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 Company accounts for its Notes in accordance with ASC 470-20 "Debt with Conversion and Other Options". The Company separately accounts for the liability and equity components of convertible debt instruments. The liability component at issuance is recognized at fair value, based on the fair value of a similar instrument that does not have a conversion feature. The equity component is based on the excess of the principal amount of the debentures over the fair value of the liability component, after adjusting for an allocation of debt issuance costs, and is recorded in additional paid-in capital. Debt discount is amortized as additional non-cash interest expense over the expected life of the debt using the effective interest rate method. In accounting for the issuance costs related to the Notes, the issuance costs incurred were allocated between the liability and equity components based on their relative values. The Company’s Notes are included in the calculation of diluted EPS if the assumed conversion into common shares is dilutive, using the “if-converted” method. This involves adding back the periodic interest expense net of tax associated with the Notes to the numerator and by adding the shares that would be issued in an assumed conversion (regardless of whether the conversion option is in or out of the money) to the denominator for the purposes of calculating diluted EPS, unless the Notes are antidilutive (See Note 11).

The annual effective interest rate of the liability component is 2.10% for the Notes which remains unchanged from the Notes issuance date. The following table presents the total amount of interest expenses recognized related to the Notes for the three and nine months ended September 30, 2020: September 30, 2020 Amortization of debt discount $ 131 Amortization of debt issuance costs 37 Total interest expenses $ 168 Total initial issuance costs of $14,632 related to the Notes were allocated between the liability and equity components in the same proportion as the allocation of the total proceeds to the liability and equity components. Issuance costs attributable to the liability component are being amortized to interest expense over the respective term of the Notes using the effective interest rate method. The issuance costs attributable to the equity component were netted against the respective equity component in additional paid-in capital. The Company initially allocated issuance costs of $13,502 and $1,130 to the liability and equity components, respectively. As of September 30, 2020, the if-converted value of the Notes did not exceed the principal amount.

COMMITMENTS AND CONTINGENT LIABILITIES	NOTE 9:- COMMITMENTS AND CONTINGENT LIABILITIES a. Guarantees: As of September 30, 2020, contingent liabilities exist regarding guarantees in the amounts of $18,643, $2,176 and $240 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 and suppliers, which cannot be cancelled without penalty. The Company utilizes third parties to manufacture its products. In addition, it acquires raw materials or other goods and services, including product components, by issuing to suppliers authorizations to purchase based on its projected demand and manufacturing needs. As of September 30, 2020, the Company had non-cancellable purchase obligations totaling approximately $326,661 out of which the Company already recorded a provision for loss in the amount of $3,118. As of September 30, 2020, the Company had off-balance sheet contractual obligations for capital expenditures totaling approximately $114,526. These commitments reflect purchases of automated assembly lines and other machinery related to the Company’s manufacturing. 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, alleges that SolarEdge's 12.5kW - 27.6kW inverters infringe two of the plaintiff’s patents. In its complaint, SMA requests inter alia an injunction and a determination for a claim for damages for sales in Germany. Plaintiff also asserted a value in dispute of EUR 5.5 million (approximately $6,450) 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. 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. F - 23 SOLAREDGE TECHNOLOGIES, INC.

In May 2019, the Company was served with three lawsuits by Huawei Technologies Co., Ltd., a Chinese entity (“Huawei”), against the Company's two Chinese subsidiaries and its equipment manufacturer in China. The lawsuits, filed in the Guangzhou intellectual property court, allege infringement of three patents and ask for an injunction of manufacture, use, sale and offer for sale, and damage awards of Chinese yuan (“CNY”) 30 million (approximately $4,250). A first-instance judgment was issued on August 7, 2020 ordering the Company to pay damages in the amount of approximately CNY 10.5 million (approximately $1,550), including court fees, with respect of one of the patents, which was recorded in general and administrative expenses. The Company has filed an appeal with the Supreme People’s Court of China. Following the receipt of the lawsuits, the Company filed three lawsuits in China against Huawei for unauthorized use of patented technology of the Company. These lawsuits are still in process and judgements have not been rendered. The Company believes that it has meritorious defenses to the claims asserted by Huawei and the judgement of the first instance court and intends to vigorously defend against these lawsuits. In August 2019, the Company was served with a lawsuit by certain former shareholders of S.M.R.E S.p.A (“SMRE”), against its Italian subsidiary that purchased the shares of SMRE in the tender offer which followed the SMRE Acquisition. The shareholders who tendered their shares are asking for the difference between EUR 6 per share, which is the amount they tendered their shares, and EUR 6.77 per share, for a total award of EUR 2.7 million (approximately $3,150). The Company believes it has meritorious defenses to the claims asserted and intends to vigorously defend against this lawsuit. In December 2019, the Company received a lawsuit filed by a former consultant of the Company and its Israeli subsidiary in the amount of NIS 25.5 million (approximately $7,400) claiming damages caused relating to a terminated consulting agreement and stock options therein.

Segment Reporting [Abstract]
SEGMENT INFORMATION	NOTE 14:- SEGMENT INFORMATION Following the completion of three acquisitions during 2018 and 2019, the Company has changed its segments measurement, beginning in 2019. The purpose of the new measurement is to provide the Company’s chief operating decision maker (“CODM”) better information to assess segment performance and to make resource allocation decisions. The Company now operates in five different operating segments: Solar, Critical Power (formerly known as UPS), Energy Storage, e-Mobility and Automation Machines. The Company's Chief Executive Officer is the CODM who makes resource allocation decisions and assesses performance based on the 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. F - 29 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 14:- SEGMENT INFORMATION (cont.) The Company identified one operating segment as reportable – the Solar segment. The other operating segments are insignificant individually and in the aggregate and therefore their results are presented together under “All other”. The Solar segment includes the design, development, manufacture, 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. Intersegment sales are a source of revenue for one of the operating segments included in the “All other” category. The Company accounts for intersegment sales as if the sales were to third parties, that is, at current market prices.
