Review: Ran everything on my transfer switch easily - Charged it up. Took 2 hours from 29%. Hooked it up and it runs flawlessly. Powers my well and barely breaks a sweat. This will be for our short power outages we have every couple months for around 4 hours at a time. Anything longer and I’ll charge them with a small inverter generator. So far I really like them. Haven’t hooked solar panels to them but I think they’ll do well.
Review: Producto excelente. El mejor todo en uno del mercado.
