So I have been running into issues combining my current PV system in with the new system.
I'm now contemplating getting a pair of the Sol-Ark 15k's and just offloading the microinverters. Each can take up to 20kW of input,, so I could retire my current string inverter, run the old AND new panels into the 15k's, simplify install with all of the built in pass through breaker, DC disconnect, battery backup capabilities, expandability, etc.
Is running DC that distance at 400'ish volts DC going to be an issue with that distance?
