2.5 Working Modes

The LUNA2000 converts high-voltage DC power generated by PV strings to low-
voltage DC power and stores the low-voltage DC power in the Energy Storage
Module. The LUNA2000 also converts low-voltage DC power from the Energy
Storage Module to high-voltage DC power which is then converted to AC power
through the inverter.
The LUNA2000 works in hibernation, standby, or operating mode.
