Hello!
A friend of mine had the following installed on his home last year.
- 7.6kW array (19 x 400w Q.PEAK DUO BLK ML G10+)
- SolarEdge HD Wave Inverter SE7600H-US (240v)
- SolarEdge P401 Power Optimizers for each panel.
He's in the miserable heat that is Texas, and interested in batteries to shift some of his excess production to lessen the AC overnight, and also for a grid down situation.
I don't think he'll make much of a dent in the AC with batteries and don't think it's worth it so have written a detailed check list of things he should do to first to reduce AC demand.
- log into his utility and find out how many kWh he's burning through to set a baseline.
- smart thermostat to optimize when the AC kicks on and see the speed of temperature change when it's not running.
- use the thermostat data to consider better insulation and windows.
- look into flair smart vents as it's dumb cooling the whole house all the time.
- consider a mini split with a couple of zones to lower the work for the AC.
Only once that's dealt with do the batteries.
The options I've found for his inverter are...
- SolarEdge Home battery. Expensive, and I'm not sure if it would work with his inverter or not.
- AC coupled options (Tesla Powerwall).
- Generac (I know, boo, hiss, etc).
I don't think he wants to deal with DIY (yet here I am on a DIY forum) otherwise I'd have suggested an EG4 18k and a few 48v batteries. Still it's worth asking to see if I can change his mind.
Anyone else in the SolarEdge boat who added batteries? If so, what did you opt for? Did you go mad making your house efficient first? What did you do there?
Thanks!
