2.7.5 PCS Key Features
High operating efficiency boosted by advanced three-level inverting technology.
o Peak discharging efficiency: 98%
o Peak charging efficiency: 97.6%
Grid adaptability
o Selectable grid standards: IEEE 1547, CA Rule 21, HECO.
o Smart inverter functions, including voltage ride-through (LVRT/HVRT), adjustable reactive power and power factor
(PF) value from 0.8 leading to 0.8 lagging.
Adaptive communication protocol supports Modbus TCP/IP and CANbus to ensure compatibility with third-party
monitoring systems.
Wide DC input voltage range:
o Operating DC voltage range with full power: 750-1100 V DC.
o Maximum DC input voltage: 1200 V.
Charging and discharging: Energy storage PCS can operate in grid-forming and grid-following modes. Both modes
allow battery charging and discharging
