Although if the voltage of your panels isn t a proper match to your battery or battery bank you ll need to use an m.
Distance between solar panels and inverter.
The ohmic resistance is.
But if the panels are wired in series which increases the voltage much longer wire runs can be done.
Generally it is easier to keep the solar inverter close to the solar panels and have a longer length of ac cable to the grid connection.
Power optimizers can be thought of as a compromise between string inverters and microinverters.
The shorter the better.
A panel located option to pair with a string inverter.
We use a solar cable with 4mm cable cross section area.
But 500 feet is around 160 meters so with 3 phase power and a 20 kilowatt inverter the cable from the inverter to the grid connection would need a cross section of about 50 square millimeters to keep voltage rise to under 1.
I would guess the cable distance between panels and inverter would be 15 meters.
Like microinverters power optimizers are located on the roof next to or integrated with individual solar panels.
