I hope I dont come off too big an idiot - I installed a 10.8kw system 10 years ago and will be removing that and upgrading. My goal is to have seamless transfer on power outages, upgrade watts, more techy inverters. Currently I have 400 amp service (200amp x2). My current inverters(schnieder 4.5kw) each have a 60amp breaker to power each of my 2 panels when power goes out(i have to flip a ton of breakers and its a pain). They feed the grid via 1x100amp breaker. I'm looking to overhaul everything and have been deciding between solark15k x 2 and EG4 18k x2 (leaning this way). I will be installing approx 60 Canadian solar 400amp panels evenly split between 2 inverters. Battery size 30-45kwh. Here are my questions:
1. I dont want to line side tap... Can I continue to use those 60amp breakers (1 in each panel, 1 per inverter) to feed my 200amp panels during outage?
2. Can I continue to feed the grid via 100amp breaker or will I need to do lets say ~60amp breaker per panel? 1 per inverter or how do you wire this?
3. Should I install a critical loads panel or just use 1 inverter per 200amp panel. The only time I could see overloading inverter would be if my heat pump was running during a cold day. Otherwise, its unlikely I would be pulling more than 60amps at any given time.
Any other advice? I think I have the install pretty well figured out other than how to feed my main breaker panels. It's sooooo much simpler than 10 years ago.
