Hello. I am designing a new system for a recent build to include a backup generator, solar, battery storage, with a fully backed up main panel and non-backed up EV panel. I have a meter + single 200 amp disconnect on the exterior of the home (Siemens - MM0202B1200RJB) and I'm wondering the most cost effective method of splitting this into two feeds leaving the main disconnect box.
Any other ideas are welcome. I'd like to do this without replacing the meter box. I'm a very capable home owner (done multiple whole-house wiring projects, sub panels, overhead-to-underground service conversations, etc.) but this is a new one for me.
For context, here is what I am planning:
200 amp service into combo Meter/Disconnect (200amp)
200 amp grid service into Sol-Ark 18K
Dual 16.7kW battery storage into Sol-Ark 18K
14kW Solar into Sol-Ark 18k
10kW backup generator into Sol-Ark 18K
200 amp service from Sol-Ark to 200 amp main load center (w/200 amp main breaker)
-- Sol-Ark allows 200 amp service pass-through when grid is up
125 amp EV panel split off before Sol-Ark 18k so it is not backed up when grid is down
