Enphase
Company Overview
Enphase Energy, Inc.
Fremont, California, United States
2006
Approximately 3,000 employees worldwide (source: salestools.io). Revenue of $1.3 billion (source: cbinsights.com).
What They Do
Enphase Energy focuses its core technology on solar energy through semiconductor-based microinverters that convert DC power from individual solar modules to AC at the panel level. This innovative approach is integrated with proprietary networking and software for monitoring and control, as well as battery storage solutions like IQ Batteries and electric vehicle chargers. These technologies enable the generation, use, storage, and sharing of solar power, making Enphase a leader in the solar energy sector (source: cbinsights.com). Their product lineup includes microinverters compatible with virtually every solar panel, AC modules, and award-winning smart batteries such as the IQ Battery 5P. Additionally, they offer a leading mobile app for real-time energy data, control, and payment for excess power shared with communities, forming the Enphase Energy System for residential and commercial solar-plus-storage setups (source: enphase.com). Target markets encompass residential homeowners and commercial sectors in the United States and internationally, prioritizing clean energy solutions for self-consumption, grid interaction, and energy independence (source: cbinsights.com). Enphase holds a competitive position as a leader in microinverter-based solar technology, differentiating through module-level power conversion for higher reliability and scalability over traditional string inverters (source: enphase.com).
Projects & Track Record
Enphase Energy has a significant track record with over 5 million deployed systems globally and more than 84.8 million microinverters shipped since its inception in 2006 (source: enphase.com). While specific named projects with capacities, locations, or costs are not publicly detailed, the company's scale implies extensive involvement in residential and commercial solar-plus-storage deployments. Key clients include residential users and commercial entities adopting solar self-generation, with partnerships evident in utility interactions, although no major clients are specifically named (source: cbinsights.com). Enphase's geographic presence spans over 160 countries, with a strong focus on the U.S. market, particularly in California, where it continues to expand its operations (source: enphase.com).
Recent Developments
In the last two years, Enphase has announced increased deployments of its Legacy NEM System Expansion Solution in California, where utilities have streamlined approvals for expanding existing solar systems under net energy metering rules (source: zoominfo.com). On February 11, 2025, the company launched the expanded IQ Battery 5P solution tailored for new home projects in California, enhancing storage capabilities for residential solar setups (source: zoominfo.com). While no major acquisitions or mergers have been reported post-IPO, the company continues to focus on product milestones, including a patent grant for a piezoelectric power converter with trajectory control related to photovoltaics and power supplies (source: cbinsights.com).
Working There
Enphase offers a variety of roles across key departments at its Fremont headquarters, including engineering, product management, sales and marketing, and operations. Specific roles include software development, hardware design, business development, and customer success, with leadership positions such as Chief Executive Officer & President and specialized roles like Director of Cloud and IoT (source: salestools.io). The company culture emphasizes innovation, collaboration, continuous learning, and employee well-being, which is reflected in the amenities at their headquarters, such as open-plan offices, collaboration spaces, fitness centers, and wellness rooms designed to foster teamwork and attract top talent (source: salestools.io).

- Develop and execute test strategies to ensure safety and optimal functionality of Enphase's firmware to meet worldwide standards.
- Design and implement automated test systems in Python and Ruby, enabling continuous integration for the firmware development team.
- Validate firmware communication interfaces and protocols (e.g., Ethernet/TCP-IP, Modbus/TCP, I2C, SPI, UART, SMBus, and power line carrier) using protocol and logic analyzers.
- Collaborate with hardware and firmware engineers to ensure firmware is designed for test.
- Confer with Quality Assurance, Development, and Product Management on project planning, and ensure effective testing of Enphase's firmware within design constraints.
- Use test automation, power meters, oscilloscopes, DC supplies, and other lab test equipment to ensure complete functional, efficiency, and safety test coverage for Enphase's hardware and firmware.
- Coach and train new members of the technical staff on Enphase's test equipment, procedures, and automation software.
Who You Are and What You Bring
- BS/MS in Electrical Engineering, Electronics Engineering, and/or Computer Science.
- 5+ years of experience in a similar role as an embedded firmware test/DVT/QA engineer.
- Strong Python programming for controlling test equipment, test framework development, and test automation, including Python bindings for Linux and communication packages (TCP/IP sockets, SMBus, pyModbusTCP, PiCloud, etc.).
- Functional validation experience with Ethernet/I2C/SPI/UART/power line carrier-based communication systems, and use of protocol and logic analyzers.
- Experience across the stages of embedded firmware (preferably Linux/RTOS-based) design, implementation, test, deployment, and maintenance.
- Experience with firmware integration and testing.
- Experience with 800V-1500V high-voltage DC and 277/480V three-phase AC voltages.
What Will Make You Stand Out
- Basic knowledge of relevant worldwide standards such as IEEE 1547, 1741 SA, CA Rule 21, HECO SRD 1.1, AS/NZS 4777.2:2015, SAND2013-9875, UK G83/2, and Sandia standards.
- Knowledge of worldwide advanced grid functions and fault conditions.
- Familiarity with AC grid simulators and solar panel simulators.
