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 the table below to select proper amperage, 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

Please follow the steps below to implement battery connection:
1.
Assemble battery ring terminal based on recommended battery cable and terminal size.
2.
Connect all battery packs as the diagram below. It’s suggested to connect battery with at least 200Ah
capacity.
3.
Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are
tightened with torque of 2.5-3 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.
