What a swap over...we have a muni project where the higher voltage optimizers on the 480v inverter allowed us to minimize conductor sizing. New central inverter would need to support strings that use that size. And then the labor to remove all those optimizers! But we're replacing one of those inve
uctor back to the
Fronius 10.0 where we used the distribution plate to spead the amperage
across the six string input channels.
I'm stuck - any thoughts on other potential arc-fault causes?

er switch where both
the grid and the backup position are open (still allows PV grid-tied
operations to sell back to grid and partially offset loads during normal
grid ops) but closes the grid connection during grid failures so that the
battery backup provides power (with 2 Radians only).

indicated above?
- If the 4th wire is a neutral (I certainly hope it is), where
might I find the ground electrode conductor (the building is relatively new,
less than 10 years I believe.). FYI, the building is metal.
I look forward to your comments
