Hello I just ordered from Texas a Growatt SPF 5000ES, 2 x Eg4 48v 100Amp batteries, and the transformer to balance 120volts. This is my 1st dive into solar and wish to start out as a UPS for a Well pump and a few select 120 loads. I will locate system in my unfinished basement about 30 feet away from House service panel. I want to run A/c power to Inverter and also run a 220 line back directly to the well pump which is back by house service panel. Currently the well pump runs off a 220v 20amp breaker. I will have small breaker panel next to the Growatt inverter for outbound 220/120 feeds. On the input side I believe I see in the Manual they recommend a 50amp breaker for the A/c input side, this will not be in the outbound breaker box. So I assume i'll have a 220v 20amp breaker in my solar breaker panel then run that back to well pump. Im getting confused by Romex wire sizes needed for this distance especially for the 50 amp inbound feed to the inverter, and i would assume leaving the house Service panels would need a 50amp breaker there to start? I/m looking for any good diagrams and advice to help plan this please.
I will also be running 3 370watt 120 cell panels on a ground mount to as my solar power side.
Thanks, Im excited and interested in this community and hope to some day be on the info providing side but for now, I'm a newbie.
