6.5 Connecting the battery cable

• The battery used with the inverter shall be approved by the inverter manufacturer. The
approved battery list can be obtained through the official website.
• A short circuit in the battery may cause personal injury. The instantaneous high current
caused by a short circuit can release a large amount of energy and may cause a fire.
• Before connecting the battery cable, ensure the inverter and the battery, and
downstream&upstream switches, are all disconnected.
• It is forbidden to connect and disconnect the battery cables when the inverter is running.
Otherwise it may cause electric shock.
• Do not connect one battery pack to more than one inverter at the same time. Otherwise, it
may cause damage to the inverter.
• It is forbidden to connect loads between the inverter and batteries.
• When connecting battery cables, use insulated tools to prevent accidental electric shock or
short circuit to the batteries.
• Ensure that the open circuit voltage of the battery is within the permissible range of the
inverter.
• Install a DC breaker between the inverter and the battery.
• Connect the battery cables to the corresponding terminals such BAT+, BAT- and grounding
ports correctly. Otherwise it will cause damage to the inverter.
• Ensure that the whole cable cores are inserted into the terminal holes. No part of the cable
core can be exposed.
• Ensure that the cables are connected securely. Otherwise it will cause damage to the
inverter due to overheat during its operation.
• Delayed charge cannot be set to 100% if the PV is oversizing.
