4.4. Battery Connection
For safe operation and compliance, an individual DC overcurrent protector or disconnection
device is required for the connection of the battery and the inverter. Users are recommended to
utilise a suitable fuse and DC isolator (see next page). In some applications, switching devices
may not be required, but overcurrent protectors must be used. Please refer to the typical am-
perage in the table below for the required fuse or circuit breaker size.
Model Wire Size Cable (mm

) Torque value (max.)
8kW 1AWG 40 24.5N.m
10kW 1/0 AWG 60 24.5N.m
12kW 1/0 AWG 60 24.5N.m
Please follow below steps to implement battery connection:
1. Please choose a suitable battery cable (appropriate rating) with the correct connector to
attach to the battery terminals.
2. Use a suitable screwdriver that matches the bolt size to unscrew the bolts to fit the battery
connectors. Then tighten the bolts with the connectors in place with a torque of 24.5N.m
in a clockwise direction.
3. Make sure polarity is correct at both the battery and inverter terminals
Battery connector screw size: M10.
Reverse Polarity
All wiring/connecting must be performed by qualified personnel. Before making
the final DC connection or closing the DC Breaker/disconnection device, ensure
the inverter unit is wired correctly. A reverse-polarity connection on the battery will
damage the inverter.
