500 kW Energy Storage Inverter
Reliable service in the most
demanding applications
Engineered to provide years of reliable
service in the most demanding applications.
EPC’s advanced smart inverters for energy storage will enable
you to deploy scalable power conversion systems with less
effort and in less time. Integrating 1,000 V class battery
energy storage systems has never been easier or more
compact. With world-class power density and an easy to install
design, your energy storage system will be up and running in
no time.
This inverter is designed from the ground up with
simplicity, reliability, and scalability in mind. The liquid-
cooled inverter includes an integrated AC contactor,
AC breaker, DC contactor, and precharge circuit, enabling
simple installation.
The PD500/AC-480 provides reliable, abundant power in a
small footprint for years of reliable service.
