Long time listener, first time caller in the energy category. Last year I had Tesla install a 10 kW solar system, and it was a pretty terrible experience. One inverter was wired incorrectly, the other was configured incorrectly, so I was actually capturing less than half of what the system could produce. Then they wouldn't come out to check it because they had not heard from the utility, even though a tech had seen the door tag, so they wouldn't turn on monitoring. To top it off, they underprovisioned one of the inverters, so I'm clipping an hour or two a day in typical Florida sun, probably missing out on a kWh or 2 every day. So while my trust with Tesla is already pretty low given how inept they were with the install, after two years of waiting for a Powerwall 2 earned by referral, they're ready put one in for me. My solar setup consists of two parts: 4 kW of panels on a 4.2 kW inverter, and 6 kW of panels on a 5 kW inverter. I don't fully understand what happens between the inverters and the meter, but from the mains there are two 150 amp panels and a 40 amp circuit directly to one of my AC pumps outside (the second one is wired to one of the panels, which doesn't make a lot of sense to me). For my "free" Powerwall, which I'll have to pay them to install, they're saying that in a power outage situation, only the 5 kW inverter can feed my house, so I'll lose half of my generation while disconnected from the grid. I realize the Powerwall can only take something like 7 kW as an input, but that they can't make this work leaves me skeptical. I do realize that the Powerwall probably requires some circuit shuffling so it can power just the essentials in an extended outage (think hurricane), but the suggestion that I have to leave half the solar system idle, unless I buy a second unit of course, leaves me feeling like their system is terrible or they just don't know what they're doing. Any thoughts or suggestions?
