Why APsystems' Micro-inverter?

APsystems Microinverter technology maximizes power generation for each module in the PV array, boosting system efficiency by up to 20 percent compared to conventional “string” systems

When combined with the APsystems Communicator and APsystems Monitor, the APsystems Microinverter lets you track the performance of each module in your PV array through any web-enabled device.

A single APsystems YC500 microinverter unit handles two PV modules, significantly lowering installation and balance-of-system costs. Our fourth-generation YC1000 handles 3 or 4 modules per unit, enabling large-scale, 3-phase commercial solar at an unprecedented price point.

APsystems Microinverters tie directly to the low-voltage DC module, enhancing homeowner safety and eliminating the possibility of high-voltage “arc” fires. All APsystems products undergo rigorous factory testing, evaluation and field tracking, and are built to a 25-year design life.
