Because thousands of people bought B Grade panels are premium rates as Tier 1 brands. So when they fail, burn down and cause havoc. There's no recourse.
Tesla and enphase is the best combination in terms of life span of a system. Tesla for me, doesn't have any issues as far as battery/inverter faults, a simple sliding bar in the settings tab in your app will adjust your battery reserve and your on your way.
I have personally seen the new...
Powerwalls are liquid cooled units, hence why they offer 80% guaranteed life, unlimited discharge cycles, 100% to 0% depth of discharge unlimited times a day. Most other batteries have DOD 80 or 90 % with a single cycle a day and then the warranty fine print.
Also the tesla app is years ahead...
