Electrical Connection
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.
•
Connecting the BMS communication cable for battery communication when conneting the
inverter to the battery. For more detailed instructions, refer to
Meter Communication Cable.
•
The batteries and inverters should be connected in different ways when the inverter models differ
or the number of batteries differ, as explained below:
