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), (iii) a related cloud-based monitoring platform, that collects and processes information from the power optimizers and inverters of a solar PV system to enable customers and system owners as applicable, to monitor and manage the solar PV systems and (iv) a storage solution that is used to increase energy independence and maximize self-consumption for homeowners by utilizing a battery that is sold separately by third party manufacturers, to store and supply power as needed (the “StorEdge solution”). The StorEdge solution is designed to provide smart energy functions such as maximizing self-consumption, Time-of-Use programming for desired hours of the day, and home energy backup solutions. The Company and its subsidiaries sell their 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”). Since 2018, the Company completed certain strategic acquisitions in order to further expand its business. In July and October 2018, the Company completed the acquisition ("Gamatronic Acquisition") of substantially all of the assets and activities of Gamatronic Electronic Industries Ltd ("Gamatronic IL") and all of the outstanding shares of its wholly owned subsidiary Gamatronic (UK) Limited (“Gamatronic UK”), respectively. Both companies ("UPS Division") are providers and manufacturers of Uninterruptible Power Supplies ("UPS") devices. On October 17, 2018, the Company completed the acquisition of 74.5% of the outstanding common shares and voting rights of Kokam Co., Ltd. (“Kokam”), a Korean company whose shares are traded on the Korean OTC market, a provider of Lithium-ion cells, batteries and energy storage solutions. From October 17, 2018 and through March 31, 2019, the Company increased its shareholdings of Kokam to 94.2%. On January 24, 2019, the Company completed the acquisition of 56.8% of the outstanding common shares and voting rights of S.M.R.E S.p.A (“SMRE”), an Italian company whose shares were traded on the Italian AIM, a provider of innovative integrated powertrain technology and electronics for electric vehicles (see note 2). b. New accounting pronouncements not yet effective: In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". ASU 2017-04 was issued to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. The amendments in ASU 2017-04 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. The Company is evaluating the potential impact of this pronouncement. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses. ASU 2016-13 also applies to employee benefit plan accounting, with an effective date of the first quarter of fiscal 2022. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated balance sheets, statements of operations and cash flows. c. Recently issued and adopted pronouncement: In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016-02 (Topic 842) "Leases". Topic 842 supersedes the lease requirements in Accounting Standards Codification (ASC) Topic 840, "Leases". Under Topic 842, lessees are required to recognize assets and liabilities on the balance sheet for most leases and provide enhanced disclosures. ASU No. 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. In July 2018, the FASB issued amendments in ASU 2018-11, which provide a transition election to not restate comparative periods for the effects of applying the new standard. This transition election permits entities to change the date of initial application to the beginning of the earliest comparative period presented, or retrospectively at the beginning of the period of adoption through a cumulative-effect adjustment. The Company has elected to apply the standard retrospectively at the beginning of the period of adoption through a cumulative-effect adjustment. The Company has also elected certain relief options offered in ASU 2016-02 including certain available transitional practical expedients. The Company adopted Topic 842 effective January 1, 2019. The Condensed Consolidated Financial Statements for the three months ended March 31, 2019 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 accompanying unaudited condensed consolidated interim financial statements have been prepared in accordance with Article 10 of Regulation S-X, “Interim Financial Statements” and the rules and regulations for Form 10-Q of the Securities and Exchange Commission (the “SEC”). Pursuant to those rules and regulations, the Company has condensed or omitted certain information and disclosures in footnotes that it normally includes in its annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). In management’s opinion, the Company has made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary to fairly present its condensed consolidated financial position, results of operations, and cash flows. The Company’s interim period operating 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, 2018, contained in the Company’s Annual Report on Form 10-K filed with the SEC on February 28, 2019, have been applied consistently in these unaudited interim condensed consolidated financial statements, except for the adoption of ASU No. 2016-02, “Leases (Topic 842) e. The Company depends on three contract manufacturers and several limited or single source component suppliers. The Company is in the process of discontinuing its activity with one of those contract manufacturers. Reliance on these vendors makes the Company vulnerable to possible capacity constraints and reduced control over component availability, delivery schedules, manufacturing yields, and costs. These three vendors collectively accounted for 48.7% and 58.8% of the Company’s total trade payables as of March 31, 2019 (unaudited) and December 31, 2018, respectively. The Company has the right to offset its payables to one of its contract manufacturers against vendor non-trade receivables. As of March 31, 2019 (unaudited), a total of $1,784 of these receivables met the criteria for net recognition and were offset against the corresponding accounts payable balances for this contract manufacturer in the accompanying condensed consolidated balance sheets. f. Business Combination: The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair value. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired technology, useful lives and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, which is not to exceed one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings. g. Accounting for share-based compensation: Some of the RSUs granted are subject to certain performance criteria (“PSUs”): accordingly, compensation expense for PSUs is recognized when it becomes probable that the related performance condition has been satisfied. h. Certain prior period amounts have been reclassified to conform to the current period presentation.

Business Combinations [Abstract]
BUSINESS COMBINATION	NOTE 2:- BUSINESS COMBINATION S.M.R.E On January 24, 2019, the Company completed the acquisition of 56.8% of the outstanding common shares and voting rights of SMRE, a provider of innovative integrated powertrain technology and electronics for electric vehicles for approximately $73.9 million, net of cash acquired, out of which $42,240 was paid in cash and $34,601 was paid in shares of SolarEdge common stock (the “SMRE Acquisition”). As part of SMRE Acquisition, the Company issued 334,096 PSUs that are subject to certain performance goals and a vesting period, at the amount of $13,444, which will be expensed in the condensed consolidated statements of operation in general and administrative expenses line item. As of January 24, 2019, the fair value of the 43.2% non-controlling interests in SMRE is estimated to be $67.7 million. The fair value of the non-controlling interests was valued based on and at the transaction price. The primary reason for the SMRE Acquisition was to acquire technology and customer relationships and to expand and diversify the Company’s business by entering into the electric vehicles market. The Company determined that the SMRE Acquisition will be accounted for as a business combination in accordance with ASC 805 "Business Combinations". During the period from the SMRE Acquisition through March 31, 2019, the Company purchased additional common shares of SMRE in the open market, for a further investment of $1.2 million. The amounts of revenue and net loss of SMRE included in the Company’s condensed consolidated statements of operations for the period from January 24, 2019 through March 31, 2019 are $2,902 and $1,879, respectively. The following table summarizes the preliminary estimated purchase price allocation of the business combination completed during the three months ended March 31, 2019: Components of Purchase Price: Cash $ 42,240 Less cash acquired (2,925 ) Common stock 34,601 Total purchase price $ 73,916 Allocation of Purchase Price: Total net identifiable assets $ 9,916 Total identifiable intangible assets, net and Goodwill (1) 131,734 Noncontrolling interest (67,734 ) Total purchase price allocation (2) $ 73,916 (1) The intangible assets comprised primarily of technology, in process research and development and customer relationships. (2) The Company is expecting to complete the preliminary estimated purchase price allocation during the measurement period of one year from . Fair values that are still under review include among others, values assigned to identifiable intangible assets, goodwill, deferred income taxes and contingent liabilities. During the three months ended March 31, 2019, the Company recognized $453 of aggregate acquisition-related costs that were expensed in the condensed consolidated statement of operations in general and administrative expenses line item. The purchase price allocations for the business combinations completed during the year ended December 31, 2018 are still preliminary as of March 31, 2019. The following table represents the pro-forma (unaudited) condensed consolidated statements of operations as if all acquisitions completed during the year ended December 31, 2018 and the three months ended March 31, 2019, had been included in the condensed consolidated statements of operations of the Company for the three months ended March 31, 2019 (unaudited) and 2018 (unaudited): Three months ended March 31, 2019 2018 Unaudited Revenue $ 272,943 $ 231,784 Net income $ 16,610 $ 28,654 The pro-forma results have been calculated after applying the Company’s accounting policies and adjusting the results of all acquisitions to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to property, plant and equipment and intangible assets had been applied since the acquisitions date, together with the consequential tax effects. The pro-forma results are based on estimates and assumptions, which the Company believes are reasonable. The pro-forma results are not the results that would have been realized had the acquisitions actually occurred on January 1, 2018 and 2019, and are not necessarily indicative of the Company’s condensed consolidated statements of operations in future periods. The pro-forma results include adjustments related to business combinations accounting, primarily depreciation of property plant and equipment, amortization of intangible assets and together with the consequential tax effects.
