The aforementioned 3000Wp and 8000Wp is the Watt-peak which can be expected from the solar system. So for and over-sized PV array, where the total Wp installed PV panels exceeds the power of the PV Inverter, you take the Wp from the inverter. For example 7000Wp of solar panels installed, with an 6000Wp PV grid inverter, the figure to be used in the calculations is 6000Wp. | The aforementioned 3000Wp and 8000Wp is the Watt-peak which can be expected from the solar system.

It is very important to ensure the loads are well balanced in a 3 phase system with Grid Inverters. Careful attention must be paid to all Cabling DC and AC Cabling; the wire size must be rated correctly. The AC cabling must also be of the same length throughout from the Input into the Inverter/ | It is very important to ensure the loads are well balanced in a 3 phase system with Grid Inverters.
