3.3 Battery connection
Chart 3-2 Cable size
For safe operation and compliance, a separate DC over-current protector or disconnect
device is required between the battery and the inverter. In some applications, switching
devices may not be required but over-current protectors are still required. Refer to the
typical amperage in the table below for the required fuse or circuit breaker size.
All wiring must be performed by a professional person.
Connecting the battery with a suitable cable is important for safe and
efficient operation of the system. To reduce the risk of injury, refer to
Chart 3-2 for recommended cables.
Please follow below steps to implement battery connection:

battery terminals. 2. Use a suitable screwdriver to unscrew the bolts and fit the battery
connectors in,then fasten the bolt by the screwdriver,make sure the bolts are tightened
with torque of 24.5 N.M.
2. Nm in clockwise direction,make sure polarity at both the battery and inverter is
correctly connected.
3. In case of children touch or insects go into the inverter,Please make sure the inverter
