6.9 Battery Connection
This section mainly describes the cable connections on the inverter side. Refer to the in-
structions supplied by the battery manufacturer for the connections on the battery side and
configuration.
Only use properly insulated tools to prevent accidental electric shock or short cir-
cuits. If insulated tools are not available, use electrical tape to cover the entire ex-
posed metal surfaces of the available tools except their tips.
The plug connector must be connected only by trained electricians.
Do not disconnect under load!
Battery connectors must not be disconnected while under load. They can be
placed in a no load state by shutting down the inverter completely.
During the installation and operation of the inverter, please ensure that the positive
or negative polarities of batteries do not short-circuit to the ground. Otherwise, an
AC or DC short-circuit may occur, resulting in equipment damage. The damage
caused by this is not covered by the warranty.
The hybrid inverter is not connected to a battery and does not support off-grid op-
eration functions.
6.9.1 Connecting the Power Cable
A fuse with the specification of 700 V / 50 A is integrated to the BAT- terminal.
A two-pole DC circuit breaker with over-current protection (voltage rating not less
than 600 V and current rating not less than 40 A) should be installed between the
inverter and the battery.
If the battery is integrated with a readily accessible internal DC breaker, no addi-
tional DC breaker is required.
