Good morning,
I’m thinking through a power shed instead of roof mount for solar panels. All off grid. The cabin is about 80 feet away.
I can house the inverter/charger/batteries either in the power shed or in the cabin.
I have a basic understanding of voltage drop and conductor sizing. Am I correct in thinking that the difference between AC and DC is quite small?
There is a mild preference for housing the equipment in the cabin for security reasons. Under this setup, I’d have an 80’ burried DC run.
It seems to me that I can plan my panel layout to accommodate a wide range of DC voltages (to include anticipated voltage drop) with no concerns because controllers and chargers seem to be able to accept a wide range of DC. This would allow smaller conductors if they have the correct ampacity.
If I use AC, the conductor size would be more stringently dictated (I think).
Am I on the right track? Or is there a general preference or custom for this type of run between panels and the ultimate loads? Or a preference between AC and DC in this application?
Thanks
