Mcb keeps tripping.

If I assume 250W panels then the maximum pv real power is 80 x 250 = 20kW. Converted to 3 phase ac power at unity PF that is 20/3 = 7kW per phase. So 7kW x 4/5 A = 28/35A per phase. The PF of the solar inverter is more likely to be 0.9 leading. So current per phase is now 28/0.9 = 31A or 35/0.9 = 39A.If you own a caravan in NZ, it’s important to keep its parts in top shape to ensure a safe and enjoyable travel experience.
