I installed a similar EG4 inverter and battery system and had a similar experience. The big problem I ran into was that EG4 inverters are NOT compatible with my state's power grid (Hawaii) but because I had so much power, it turned out I never needed to connect to the power grid but I am loosing out on selling power. (Check with your local power company before buying!).

Another problem I had was that a week after installing, one of the TIGO units burned up and started a fire that burned a hole in a solar panel. I only noticed the problem when I saw that one of the solar arrays wasn't putting out power. Replacing the defective unit solved the problem.

Also, I had assumed I would need a generator to power through consecutive days of dark clouds but I instead opted for Ford's Pro Charger Station which has a feature that allows you to power the house; no need for a generator. However, its been over a year and not once have I needed this.

My big takeaway is this: having energy abundance is the good life when you have all electric appliances. My EV (a Ford Lightning Truck), hot tub, AC, water heaters etc have been running over a year with no problems and zero costs after the initial investment.

How many days can the truck power the house, and what's the longest stretch of overcast days you get (in Hawaii, I am gussing you get at least some sun almost every day).

Truck at 100% = 131 kwh, Minus 10% loss in transfer = 120 kwh House using 12 kwh/d = 10 days, up to 24kwh/d = 5 days

Local conditions are typically partly cloudy/rain but still system producing more than can be used.
