Reliability By Design

In a conventional PV system, inverters are the leading cause of failure. Designed to last around 10 years, inverters must be replaced at least once — and often two or three times — during the average 25-year life of a PV system, increasing the system’s overall cost.

SolarBridge believes that once a solar system is installed on a roof, it should stay there. That’s why we’re the only microinverter company that offers a 25-year warranty for a module-integrated microinverter. Matching the life of the PV module to which it’s attached, every Pantheon microinverter has been thoroughly tested and qualified by both SolarBridge and its module partners to ensure long life and reliability.

SolarBridge microinverters are designed from the ground up with reliability in mind. Our patented architecture requires a tiny fraction of the capacitance of traditional inverter architectures, enabling the use of highly reliable film capacitors instead of failure prone components such as electrolytic capacitors. SolarBridge has also eliminated other unreliable components from its design, such as opto-isolators and tantalum capacitors. Our innovative approach to thermal management keeps our microinverter products running at lower steady state temperatures, further enhancing reliability.

SolarBridge microinverters undergo a rigorous testing and qualification program — exceeding standard certification requirements to ensure they can withstand the same extreme operating conditions that a solar module endures. These include both lab and field tests with our module manufacturing partners to ensure that every AC module that arrives at a job site is pretested and prequalified for maximum performance and reliability.
