Off grid neighborhood house. I am currently wiring (2) EG4 6500 inverters for split phase 240v. Most components purchased from Signature Solar... They are helpful but tech cannot volunteer information regarding sub panel or transfer switch types or installation advice. I will have a licensed electrician look over my work before I flip the switch.
I have (21) 445 watt solar panels mounted on the roof and (6) EG4LL batteries, about 30kw. My goal is off grid but still having grid accessible for back up only when the batteries are drained from prolonged lack of sunshine/PV input. I finally understand most of the system wiring needed but am confused when researching the transfer switch and how the sub panel is wired. I am NOT feeding into the grid and must prevent that. I just need my system to power all my existing main panel loads (not just critical loads) as already wired;
I've seen a mechanical transfer switch plate in a main box (used with a gas generator) but am thinking the EG4 must have software controls that determine the order of load service. I bought an 8 space 125 amp subpanel with a 60 amp breaker and do not intend to use it for additional circuits. Do/can I use a 100 amp breaker in the main to the subpanel that has a 60 amp breaker? Is a safety/disconnect switch necessary between the subpanel and the main?
