Our non-GAAP operating expenses were $71.2 million in the second quarter of 2022, compared to $66.3 million in the first quarter of 2022, primarily due to increased investment in R&D, customer service, sales, and IT infrastructure.

Our quarterly revenue in the second quarter of 2022 was driven by strong demand for Enphase Energy Systems, powered by IQ® Microinverters and IQ Batteries. IQ8 Microinverters constituted 37% of all our microinverter shipments during the second quarter. The grid-forming IQ8 Microinverters can provide Sunlight Backup™ during an outage, even without a battery. And, with the Sunlight Jump Start feature, IQ8 Microinverters can restart a home energy system using sunlight only after prolonged grid outages that may result in a fully depleted battery.
Our IQ Battery shipments increased to 132.4 megawatt hours in the second quarter of 2022, compared to 120.4 megawatt hours in the first quarter of 2022. We shipped batteries to the United States, Germany, and Belgium during the second quarter, and made updates to improve the installer and homeowner experience. We now have more than 1,600 installers worldwide that are certified to install our IQ Batteries.
Our revenue in Europe for the second quarter of 2022 increased 69%, compared to the first quarter of 2022, led by strong growth in the Netherlands and Germany. Homeowners want self-consumption as the region not only faces rising energy prices but also a growing demand for home electrification driven by EVs and natural gas shortages. We expect to introduce IQ Batteries in more European countries during the second half of 2022.
Our strategy is to build best-in-class home energy systems and deliver them to homeowners through our installer and distribution partners, enabled by an installer platform. We have completed five acquisitions in the last six quarters, one for EV chargers and four to help create our installer platform. We shipped more than 8,250 ClipperCreek EV chargers to U.S. customers in the second quarter of 2022 and expect healthy growth going forward. We are working to move production to our manufacturing partner in Mexico, making our chargers smart and integrating the EV chargers into our home energy management systems.
We recently acquired SolarLeadFactory LLC to provide high-quality leads to our installers and further strengthen our installer platform. In January 2021, we acquired Sofdesk Inc. to provide solar design software capability and approximately 950 installers are using the Solargraf software. We acquired a business in Noida, India in March 2021 to provide proposal and permitting services for installers and are focused on automating these services. In December 2021, we acquired 365 Pronto, Inc. to simplify maintenance for installers by matching cleantech asset owners to a local and on-demand workforce of service providers. All four acquisitions aim to make life simpler for installers by providing them high-quality products and services, ultimately reducing their soft costs.
BUSINESS HIGHLIGHTS
On April 19, 2022, Enphase Energy announced that ADT Solar™, formerly Sunpro Solar, a leading rooftop solar provider and one of the fastest-growing residential solar-plus-storage service providers across 22 states in the United States, is now exclusively offering Enphase IQ8 Microinverters as part of its comprehensive home energy solution.
On May 9, 2022, Enphase Energy announced that Enphase IQ Batteries now officially support the most common third-party string inverters in Belgium and Germany, helping meet the increasing demand for energy independence in the region. Since the 2021 launch of the IQ Battery in Belgium and Germany, installers of Enphase products have seen increasing deployments of Enphase Energy Systems powered by IQ Microinverters and Enphase IQ Batteries, as well as residential solar-only energy systems powered by IQ7™, IQ7+™, and IQ7A™ Microinverters.
On May 23, 2022, Enphase Energy announced that the Enphase IQ8 Microinverter system is the first in the world to be certified by UL, a global safety science leader, to UL 1741, 3rd edition including the Supplement SB. This certification meets the new North American safety and grid interconnection standards for connecting solar inverters, energy storage systems, and distributed energy resources to the grid in compliance with IEEE 1547-2018 and IEEE 1547-1 2020.
Enphase Energy recently announced that installers in Rhode Island, Massachusetts, Washington, New Mexico, Texas, New York, Florida, Hawaii, Missouri, Michigan, Southern California, and Puerto Rico have seen growing deployments of the Enphase Energy System powered by IQ Microinverters and IQ Batteries.

Use of Non-GAAP Financial Measures
Enphase Energy has presented certain non-GAAP financial measures in this press release. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that either exclude or include amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles in the United States (“GAAP”). Reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure can be found in the accompanying tables to this press release. Non-GAAP financial measures presented by Enphase Energy include non-GAAP gross profit, gross margin, operating expenses, income from operations, net income, net income per share and free cash flow.
These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies. In addition, these non-GAAP measures have limitations in that they do not reflect all of the amounts associated with Enphase Energy’s results of operations as determined in accordance with GAAP. As such, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. Enphase Energy uses these non-GAAP financial measures to analyze its operating performance and future prospects, develop internal budgets and financial goals, and to facilitate period-to-period comparisons. Enphase Energy believes that these non-GAAP financial measures reflect an additional way of viewing aspects of its operations that, when viewed with its GAAP results, provide a more complete understanding of factors and trends affecting its business.
As presented in the “Reconciliation of Non-GAAP Financial Measures” tables in the accompanying press release, each of the non-GAAP financial measures excludes one or more of the following items for purposes of calculating non-GAAP financial measures to facilitate an evaluation of the Enphase Energy’s current operating performance and a comparison to its past operating performance:
Stock-based compensation expense. Enphase Energy excludes stock-based compensation expense from its non-GAAP measures primarily because they are non-cash in nature. Moreover, the impact of this expense is significantly affected by the Enphase Energy’s stock price at the time of an award over which management has limited to no control.
Acquisition related expenses and amortization. This item represents expenses incurred related to the Enphase Energy’s business acquisitions, which are non-recurring in nature, and amortization of acquired intangible assets, which is a non-cash expense. Acquisition related expenses and amortization of acquired intangible assets are not reflective of the its ongoing financial performance.
3


Non-cash interest expense. This item consists primarily of amortization of debt issuance costs and accretion of debt discount because these expenses do not represent a cash outflow for the Enphase Energy except in the period the financing was secured and such amortization expense is not reflective of the its ongoing financial performance.
Loss on partial settlement of convertible notes. This item is reflected in other income (expense), net and represents (i) the difference between the carrying value and the fair value of the settled convertible notes and (ii) the inducement loss for the difference between the value of the shares issued to settle the convertible notes and the value of the shares that would have been issued under the original conversion terms with respect to the repurchased Notes due 2025, which is non-cash in nature and is not reflective of the Enphase Energy ongoing financial performance.
Non-GAAP income tax adjustment. This item represents the amount adjusted to the Enphase Energy’s GAAP tax provision or benefit to present the non-GAAP tax amount based on cash tax expense and reserves.
Free cash flow. This item represents net cash flows from operating activities plus deemed repayment of convertible notes attributable to accreted debt discount reported in operating activities less purchases of property and equipment.
