AP Systems Micro-inverter

Solar panels generate Direct Current (DC).  Conventional electricity, used in homes and businesses, is Alternating Current (AC).  Inverters, also called string inverters, convert DC to AC.  Micro-inverters (MI) are integrated with solar panels itself on the roof top and output from solar panels is AC.  MI integrated solar panel installation saves time and money because dealing with high voltage DC system requires additional code compliance.

Who are AP Systems?

AP systems was founded in Silicon Valley in 2010, and is now a global leader in the development, manufacturing, and marketing of microinverters based on their own proprietary, leading-edge solar technology. A systems USA is based in Seattle.

Why AP Systems MI (APS)?

APS pioneered combining multiple solar panels to a single micro-inverter there by improving installation efficiency and increasing energy harvest.

APsystems offers advanced, powerful solar microinverter technology for residential and commercial systems. The APsystems microinverter solution combines highly efficient power inversion with a user-friendly monitoring interface to bring you reliable, intelligent energy. Their proprietary system architecture increases solar harvest and ensures maximum output for solar arrays, and we continue to develop new technologies and products for the marketplace.  In short, APS microinverters are powerful, smart, cost effective and safe. This video discusses advantages of APS Micro-inverters.


APsystems YC600 Microinverter (This is Page 22 of 40 on PDF)

With its groundbreaking design and features, the YC600 is the pinnacle of microinverter technology.


A single-phase, smart grid-compliant microinverter, the YC600 serves two modules with dual, independent MPPT. Zigbee wireless communication over a mesh network offers faster data speeds than PLC and a wider MPPT voltage range results in a greater energy harvest for homeowners.

A true utility-interactive microinverter with Reactive Power Control (RPC) technology, the YC600 meets CA Rule 21 requirements and is inherently NEC 2014/2017 Rapid Shutdown compliant. The unit also builds on the successful APsystems line of multi-module/multi-solar panels microinverters, simplifying installation and reducing logistics costs.

  • Dual module microinverter with independent MPPT

  • Utility-interactive with Reactive Power Control (RPC)

  • CA Rule 21 compliant

  • Continuous power of 274VA per channel, 300VA peak

  • Accommodates modules from 250-440W+

  • Wide MPPT voltage range (22V-45V)

  • Meets NEC 2014/2017 690.12 Rapid Shutdown requirements

  • ZigBee communication & free monitoring
