The cable size of each inverter is shown as below
Cable thickness: 50mm²
Torque value: 2 ̴ 3Nm
WARNING : Make sure the length of all cables is the same.
Otherwise, there will be voltage difference between the inverter and the battery and there is a risk that
the inverters connected in parallel will not work.
Recommended grid and load cable size for each inverter: 8AWG – 1,4 ̴ 1.6Nm
You must connect the cables of each inverter.
Take the battery cables for example: you need to use a connector or busbar as a connector to connect
the battery cables together, then connect to the battery terminal.
The cable size used from joint to battery is X times cable size to inverter.
"X" indicates the number of inverters connected in parallel.
Regarding net and load, please also follow the same principle.
PAY ATTENTION!! Install the circuit breaker on the battery and mains side.
This will ensure the inverter can be safely disconnected during maintenance and fully protected against
overcurrent from the battery or Grid.
If you want to use only one breaker on the battery side for the whole system, the rating must be
of the breaker X times the current of the inverters connected in parallel.
Recommended mains-side circuit breaker for parallel arrangement:
PB.UPS.10.10.48: 100A/230Vac
PB.UPS.15.15.48: 150A/230Vac
REMARK 1 :
You can also use a 50 amp circuit breaker, for just 1 unit, and eachinverter has a circuit
breaker at its AC input.
REMARK 2 :
For a three-phase system, you can use a 4-pole circuit breaker, where the current is equal
to the current of the phase with the most units.
