Before APsystems microinverters power your system, they pass multiple rounds of rigorous testing.
🌦️ Cold. Heat. Water. Salt spray.
Laboratory testing verified stable operation of APsystems microinverters across temperatures from −40°F to 149°F (−40°C to 65°C). IP67 water protection remained effective after one hour of immersion at a depth of approximately 3.3 feet (1 meter), while corrosion resistance testing further verified performance in demanding salt-spray environments.
For installers, partners, and project customers, long-term confidence begins with evidence. Here, that evidence comes test by test, across the conditions that shape real-world performance.
