Wrenchers,
What is the requirement for fusing 2 strings per MPPT? Specifically for an inverter like the Fronius Primo that has no integrated fuses. If you run 2 strings to each MPPT do you need to fuse each string? In this case there is a total of 4 strings which would need to be fused if using a single mppt.
If the home runs are run in separate conduits from the array to limit the strings in the conduit to 2 per you still have all 4 strings together in the inverter.
All thoughts and feedback are appreciated.
