4.4 Battery connection
Connect the positive and negative cable of the battery according to the diagram below.
4.5 PV connection
Connect the positive and negative wires of the two strings of PV according to the diagram below.
• Before connecting the battery, the circuit breaker must be disconnected to avoid the
risk of electric shock and must not be operated with electricity.
• Please ensure that the positive and negative terminals of the batteries are correctly
connected and not reversed, otherwise the inverter may be damaged.
• Please check that the cable used is sufficient for the requirements, too thin, poor
quality cables are a serious safety hazard.
• Before connecting the PV, the circuit breaker must be disconnected to avoid the risk of
electric shock and must not be operated with electricity.
• Make sure that the open-circuit voltage of the PV modules connected in series does
not exceed the maximum open-circuit voltage of the inverter (the value is 800V),
otherwise the inverter may be damaged.
