Battery Connection
CAUTION:
For safety operation and regulation compliance, it’s requested to install a separate DC over-current
protector or disconnect device between battery and inverter. It may not be requested to have a disconnect
device in some applications, however, it’s still requested to have over-current protection installed. Please refer
to typical amperage in below table as required fuse or breaker size.
WARNING!
All wiring must be performed by a qualified personnel.
WARNING!
It's very important for system safety and efficient operation to use
appropriate cable for battery connection. To reduce risk of injury, please use the

Please follow below steps to implement battery connection:
1.
Assemble battery ring terminal based on recommended battery cable and terminal size.
2.
3KVA model supports 24VDC system and 5KVA model supports 48VDC system. Connect all battery packs
as below chart. It’s suggested to connect at least 100Ah capacity battery for 3KVA model and at least
200Ah capacity battery for 5KVA model.
3.
Insert the ring terminal of battery cable flatly into battery connector
of inverter and make sure the bolts are tightened with torque of 2-3
Nm. Make sure polarity at both the battery and the inverter/charge
is correctly connected and ring terminals are tightly screwed to the
battery terminals.
WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
