Hi all you experienced installers.

I hope you can help me out on this. The situation is as follows.

The Utility connection is 23 kVA

The Grid Tied PV System will be 20,080 Wp (78 x 260 Wp)

Inverter 20 KW 3 phase

The cable from Inverter to Utility distribution board is 4 x 35 mm2

3 Phase System

What needs to be the value of the MCB / MCCB used to connect the PV System to the grid. Please show me the calculation

Thanks in advance, I do appreciate your answwers

Kind regards

Ben
