EPS(Energy Plant System):
EPS (Energy Plant System) is the power source, including commercial grid power, solar power and D.G power.
ICC (Integrated Controller and Converter):
The ICC consists of a cabinet, a temperature system, ECC500, an integrated distribution unit (IDU), power supply unit (PSU). The cabinet has both the front and back doors.
ESS (Energy Storage System):
The ESS consists of batteries and a cabinet which are integrated together with ICC inside one cabinet.
OSS (Operation Support System):
The OSS is composed of NMC (NetEco), Network(GPRS/IP), ECC500 etc, ECC500 collects power and environment parameter through serial port and I/O port and then communicates with NMC through network. It supports data collection, data transmission and data display.
