I don't know about 43kWH/5400$. But, here's the system I've been looking at:

That's 50KWH of battery, plus the 10.8KW of solar, inverters, etc., all for $17K. That system is microgrid (not grid following) capable; so, you can run it during a blackout. The switchover is pretty good, too, so you don't need a second backup system.

I would definitely get EG4 over Expert Power for the reasons posted by other commentators.

Example kit:

Add in a 15 kWh module and it's roughly the same price with better customer service, reliability, less parts, etc.

However, I would just get an EG 18k PV, 45 kWh of EG5 batteries and 11.4 kW of solar panels from signature solar and that would cost you $18.5k

If I had to recommend in all in one kit, this september 2025, I would recommend an EG4 kit from Santan Solar. At brief glance they appear to be a stronger value and is from a company with a pretty strong customer service record. This is not sponsored in anyway.
