System Overview - YASKAWA ACS-500 User Manual

2. SYSTEM OVERVIEW

The ACS-500 system is a redundant, modular energy storage solution that can be AC coupled with other
generators, such as PV or wind. The ACS-500 system comes mounted on a rack and pre-wired from the
factory. The ACS-500 can input or output 500kW and absorb or supply 300kVAr in up to 40C ambient
temperature, controlled through the pre-programmed Plant Master Controller. It can be paired with any
battery type with an equal DC voltage window. Please contact Yaskawa Solectria Solar application
engineering to verify that the voltage window of your battery and that of the ACS-500 match.
The ACS-500 system comprises 4 parts:
 DC Bus De-Combiner
 AC Combiner
 Heila PMC (optional)
 Three (3) XGI 1500–166/166-3S 166kW storage-ready inverters
