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 NEC 2014 requirements for Rapid Shutdown out of the box, ensuring safety of system installers and emergency responders.

The APsystems Microinverter Models

APsystems YC500i with EnergyMax

The APsystems YC500i with EnergyMaxTM is a grid-tied microinverter with intelligent networking and monitoring systems to ensure maximum efficiency. Highly dependable and cost effective, the YC500i with EnergyMaxTM is optimized to accommodate today’s high output PV modules effectively with up to 548W output and dual MPPT. An integrated ground allows for rapid installation for installers who prefer trunk cable architecture. Half the inverters and half the installation time means real cost savings for residential and commercial customers.

  • High output microinverter with integrated ground
  • Single unit connects two solar modules
  • Peak output power 548W
  • Individual MPPT for each module
  • PLC communication & free monitoring
  • Ideal for today’s high output PV modules
