Like microinverters power optimizers are located on the roof next to or integrated with individual solar panels.
Distance between solar panels and inverter.
The shorter the better.
We use a solar cable with 4mm cable cross section area.
Power optimizers can be thought of as a compromise between string inverters and microinverters.
The ohmic resistance is.
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.
The distance between the solar pv panels and the solar power inverter is 15 meters.
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.
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.
A panel located option to pair with a string inverter.
