• Less shading effect
  • No single point of failure
  • Turns on earlier and off later
  • Longer warranties
  • No DC cable runs
  • Less labour to install
  • Modular – expand as and when
  • Rapid shutdown if the grid goes down – Reduces risk for firefighters in case of fire

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.

APsystems microinverters give you more power, independently optimizing the output from each solar module. If one module is shaded, all the other modules in your array will still operate at full power. Built into each APsystems microinverter is a function called Maximum Power Point Tracking. Working at hundreds of times per second, the microinverter continually finds the greatest possible module power, greatly increasing overall system performance.

The microinverter installations are typically 5-15 percent more efficient than comparable “string” systems. That’s like having more solar modules on your roof with the same-sized array.

Unlike string inverters with high DC voltages in the hundreds of volts, APsystems microinverters tie directly to the low-voltage PV module and connect to the public power grid via standard AC voltages – enhancing worker and homeowner safety, and eliminating the possibility of high-voltage DC “arc” fires. The Rapid Shutdown functionality is built into every APsystems microinverter.
