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 solution designed to maximize power generation at the individual photovoltaic (“PV”) module level while lowering the cost of energy produced by the solar PV system and providing comprehensive and advanced safety features. The Company’s products consist mainly of (i) power optimizers designed to maximize energy throughput from each and every module through constant tracking of Maximum Power Point individually per module, (ii) inverters which invert direct current (DC) from the PV module to alternating current (AC) including the Company’s future ready energy hub inverter which supports, among other things, connection to a DC- coupled battery for backup capabilities, (iii) a remote cloud-based monitoring platform, that collects and processes information from the power optimizers and inverters to enable customers and system owners, to monitor and manage the solar PV system (iv) a residential storage and backup solution which includes a company designed and manufactured lithium-ion DC-coupled battery that is used to increase energy independence and maximize self-consumption for homeowners including a battery, and (v) additional smart energy management solutions. 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 acquisitions. The Company now offers a variety of energy solutions, which include lithium-ion cells, batteries, and energy storage systems (“Energy Storage”), full powertrain kits for electric vehicles, or EVs (“e-Mobility”), uninterrupted power supply solutions or UPS (“Critical Power”), as well as automated machines for industrial use (“Automation Machines”). In June 2022, the Company decided to discontinue its stand-alone Critical Power activities. The Company determined that the discontinuance of the Critical Power business doesn't represent a strategic shift that will have a major effect on the Company's operations and financial results and therefore it did not meet the criteria for discontinued operations classification. c. 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, 2021, contained in the Company’s Annual Report on Form 10-K filed with the SEC on February 22, 2022, have been applied consistently in these unaudited interim condensed consolidated financial statements. Certain prior year amounts have been reclassified to conform to current year presentation. d. 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 and the conflict in Ukraine, 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 available-for-sale marketable debt securities, or an increase in the Company’s insurance liabilities as of the time of a relevant measurement event. e. Concentrations of supply risks: The Company depends on two contract manufacturers and several limited or single source component suppliers, including, Samsung SDI, that provides lithium-ion battery cells required for the Company's residential storage solution. 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 June 30, 2022, and December 31, 2021, two contract manufacturers collectively accounted for 31.9% and 27.9% of the Company’s total trade payables, net, respectively. In the second quarter of 2022, the Company announced the opening of “Sella 2”, a two gigawatt-hour (GWh) Li-Ion battery cell manufacturing facility located in South Korea. Sella 2 is currently in testing phase with ramp-up expected during the second half of 2022. Sella 2, is the Company's second owned manufacturing facility following the opening of the Company's manufacturing facility in the North of Israel, “Sella 1” in 2020. f. New accounting pronouncements not yet adopted: From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard setting bodies are adopted by the Company as of the specified effective date. The Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption. g. Recently issued and adopted pronouncements: In October 2021, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (Topic 805). This ASU requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities (deferred revenue) from acquired contracts using the revenue recognition guidance in Topic 606. At the acquisition date, the acquirer applies the revenue model as if it had originated the acquired contracts. The ASU is effective for annual periods beginning after December 15, 2022, including interim periods within those fiscal years. Adoption of the ASU should be applied prospectively. Early adoption is also permitted, including adoption in an interim period. The Company elected to early adopt ASU 2021-08 on January 1, 2022, and will apply this new guidance to all business combinations consummated subsequent to this date. Currently, this ASU has no material impact on our consolidated financial statements. In November 2021 the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. Under ASU 2021-10, the accounting entities with transactions with a government that are accounted for by analogy to a grant or contribution accounting model are required to annually disclose certain information regarding the transaction including: (i) nature and related accounting policy used; (ii) line items on the balance sheet and income statement affected by the transactions; (iii) amounts applicable to each line item; and (iv) significant terms and conditions. This guidance is effective for financial statements issued for annual periods beginning after 15 December 2021. The adoption of this ASU will have a minor impact on the disclosures to the annual consolidated financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	NOTE 5: DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES 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 six months ended June 30, 2022, 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 June 30, 2022, the Company entered into forward contracts and put and call options to sell and buy U.S. dollars (“USD”) for NIS in the amount of approximately $75 million and $34 million, respectively. 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, under "Financial expense, net". As of June 30, 2022, the Company entered into forward contracts to sell Australian dollars (“AUD”) for U.S. dollars in the amount of AUD 10 million. As of June 30, 2022, the Company entered into forward contracts to sell Euro for U.S. dollars in the amount of €18 million. The fair value of derivative assets as of June 30, 2022, and December 31, 2021, was $2,348 and $4,009, which was recorded in prepaid expenses and other current assets in the Consolidated Balance Sheets, respectively. The fair value of derivative liabilities as of June 30, 2022, and December 31, 2021, was $4,123 and $169, which was recorded in accrued expenses and other current liabilities in the Consolidated Balance Sheets, respectively. For the three months ended June 30, 2022, and 2021, the Company recorded a gain in the amount of $3,009 and $820, respectively, in financial expense, net, related to the derivative instruments not designated as cash flow hedges. For the three months ended June 30, 2022 and 2021, the Company recorded an unrealized loss in the amount of $6,351, net of tax effect and an unrealized gain in the amount of $841, net of tax effect, respectively, in “accumulated other comprehensive loss” related to the derivative assets designated as hedging instruments. For the six months ended June 30, 2022, and 2021, the Company recorded a gain in the amount of $3,943 and $4,355, respectively, in financial expense, net, related to the derivative instruments not designated as cash flow hedges. For the six months ended June 30, 2022 and 2021, the Company recorded an unrealized loss in the amount of $7,529, net of tax effect and an unrealized gain in the amount of $713, net of tax effect, respectively, in “accumulated other comprehensive loss” related to the derivative assets designated as hedging instruments.

CONVERTIBLE SENIOR NOTES	NOTE 10: 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 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 to, but excluding the fundamental change repurchase date.

The market condition for the PSUs is based on the Company’s total shareholder return ("TSR") compared to the TSR of companies listed in the S&P 500 index over a one to three year performance period. The Company uses a Monte-Carlo simulation to determine the grant date fair value for these awards, which takes into consideration the market price of a share of the Company’s common stock on the date of grant less the present value of dividends expected during the requisite service period, as well as the possible outcomes pertaining to the TSR market condition. The Company recognizes such compensation expenses on an accelerated vesting method. The aggregate maximum number of shares of common stock that may be issued on the exercise of incentive stock options is 10,000,000. As of June 30, 2022, an aggregate of 8,617,974 options are still available for future grant under the 2015 Plan.

COMMITMENTS AND CONTINGENT LIABILITIES	NOTE 12: COMMITMENTS AND CONTINGENT LIABILITIES a. Guarantees: As of June 30, 2022, contingent liabilities exist regarding guarantees in the amounts of $5,892, $2,815, and $1,388 in respect of office rent lease agreements, projects with customers, 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 and other purchase orders, which cannot be canceled without penalty. 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 June 30, 2022, the Company had non-cancelable purchase obligations totaling approximately $1,532,469, out of which the Company recorded a provision for loss in the amount of $5,408. As of June 30, 2022, the Company had contractual obligations for capital expenditures totaling approximately $92,915. 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 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, alleges that SolarEdge's 12.5kW - 27.6kW inverters infringe two of the plaintiff’s patents. SMA asserted a value in dispute of EUR 5.5 million (approximately $5,714) 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 and 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 was served with three lawsuits by Huawei Technologies Co., Ltd., a Chinese entity (“Huawei”), against its two Chinese subsidiaries and equipment manufacturer in China. In May 2022, the Company announced that it had agreed on a global patent license agreement with Huawei. The agreement includes a cross license that covers patents relating to both companies' products and resulted in the settlement of all pending patent litigation between the companies. 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 $7,286) 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 June 30, 2022, accrued amounts for legal claims of $141 were recorded in accrued expenses and other current liabilities.

Income Taxes
INCOME TAXES	NOTE 15: INCOME TAXES The effective tax rate for the three months ended June 30, 2022, and 2021 was 30.5% and 16.2%, respectively, and for the six months ended June 30, 2022, and 2021 the effective tax rate was 28.2% and 18.2%, respectively. The increase in the effective tax rate in the current year, is primarily due to a different allocation of income among the Company’s US, Israeli, and foreign subsidiaries and the change to Section 174 of the U.S Internal Revenue Code, which went into effect on January 1, 2022. The change eliminates the option to deduct research and development expenditures currently and requires taxpayers to amortize them over five years (if generated from a US entity) and fifteen years (if generated from non-US entities). This change resulted in an increase in the Company’s taxable income and Global Intangible Low Taxed Income (“GILTI”) tax. As of June 30, 2022, and December 31, 2021, unrecognized tax benefits were $2,403 and $2,192, 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 immaterial as of June 30, 2022, and December 31, 2021.

Segment Reporting [Abstract]
SEGMENT, GEOGRAPHIC AND PRODUCT INFORMATION	NOTE 17: SEGMENT, GEOGRAPHIC AND PRODUCT INFORMATION The Company operates in five different operating segments: Solar, Energy Storage, e-Mobility, Critical Power and Automation Machines. In June 2022, the Company decided to discontinue its stand-alone Critical Power activities, see also Note 1b. 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. 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, related to Accounting Standard Codification 606, “Revenue from Contracts with Customers” (ASC 606). Segment profit is comprised of gross profit for the segment less operating expenses that do not include amortization of purchased intangible assets, impairments of goodwill and intangible assets, 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 co-mingled. 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 and a residential storage solution, compatible with the Company’s energy hub inverter, intended to store and supply power for back-up and to maximize self-consumption. The Solar segment solution consists mainly of the Company’s power optimizers, inverters, batteries, and cloud‑based monitoring platform. The “All other” category includes the design, development, manufacturing, and sales of energy storage products, e-Mobility products, UPS products, and automated machines. The following table presents information on reportable segments profit (loss) for the period presented: Three Months Ended Six Months Ended Solar All other Solar All other Revenues $ 687,599 $ 40,029 $ 1,295,596 $ 86,977 Cost of revenues 494,400 38,948 918,900 83,289 Gross profit 193,199 1,081 376,696 3,688 Research and development $ 49,141 $ 8,587 $ 92,272 $ 16,517 Sales and marketing 28,419 3,283 54,224 5,857 General and administrative 16,396 3,789 32,245 7,414 Segments profit (loss) $ 99,243 $ (14,578 ) $ 197,955 $ (26,100 ) Three Months Ended Six Months Ended Solar All other Solar All other Revenues $ 431,449 $ 48,509 $ 807,736 $ 77,625 Cost of revenues 270,249 46,921 497,082 77,404 Gross profit 161,200 1,588 310,654 221 Research and development $ 35,592 $ 7,258 $ 67,494 $ 13,523 Sales and marketing 20,889 2,553 39,631 5,050 General and administrative 11,768 3,419 25,040 6,920 Segments profit (loss) $ 92,951 $ (11,642 ) $ 178,489 $ (25,272 ) The following table presents information on reportable segments reconciliation to consolidated revenues for the periods presented: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Solar revenues $ 687,599 $ 431,449 $ 1,295,596 $ 807,736 All other revenues 40,029 48,509 86,977 77,625 Revenues from finance component 146 99 281 185 Consolidated revenues $ 727,774 $ 480,057 $ 1,382,854 $ 885,546 The following table presents information on reportable segments reconciliation to consolidated operating income for the periods presented: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Solar segment profit $ 99,243 $ 92,951 $ 197,955 $ 178,489 All other segment loss (14,578 ) (11,642 ) (26,100 ) (25,272 ) Segments operating profit 84,665 81,309 171,855 153,217 Amounts not allocated to segments: Stock based compensation expenses (37,074 ) (24,052 ) (71,181 ) (47,205 ) Impairment of goodwill and intangible assets (4,008 ) - (4,008 ) - Disposal of assets related to Critical Power (4,314 ) - (4,314 ) - Other unallocated expenses, net (3,257 ) (1,698 ) (5,476 ) (6,325 ) Consolidated operating income $ 36,012 $ 55,559 $ 86,876 $ 99,687

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 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.
