4.7 Electrical connection
4.7.1 Input requirements
The battery DC voltage of the energy storage device is within the
required input range, otherwise the energy storage device will not
work. When users configure the number of batteries in series, they
need to fully consider the maximum charging voltage and the
minimum discharge voltage. For details, you can consult our technical
service personnel.
4.7.2 Output requirements
•
The output of energy storage device is three-phase three wire.
When the energy storage system is designed, its output side can be
connected to the low-voltage grid through the isolation transformer.
•
The output of grid connection side is three-phase five wire.
•
The output of load side is three-phase five wire.
•
The output of micro source side is three-phase five wire.
4.7.3 Wiring method
The whole system adopts the wiring mode of down in and down out,
and the cable is dropped into the cable trench through the wire hole
on the base. Open the back door, you can see the wiring port of the
circuit breaker. Select a single or multiple cable with appropriate wire
diameter. It is recommended that the current on the 1 mm
