The APsystems Microinverter

APsystems microinverters mark a breakthrough in solar technology, making PV arrays more powerful, smart, bankable, cost effective and safe.

Conventional “string” systems only operate as efficiently as the lowest-performing module, meaning reduced output from a shadow or leaf on one module cuts output across all modules in the array.

The APsystems microinverter is smarter.

Our microinverter technology individually monitors and maximizes power generation for each module in the array, boosting system efficiency by up to 20 percent. One APsystems unit handles two PV modules, lowering installation and balance-of-system costs.

All APsystems microinverters are engineered to comply with local grid requirements, ensuring safety of system installers and emergency responders.
