Hi, I have a Solar Edge system installed last year. I decided to wait on batteries as I wasn't impressed with the 2 battery choices offered. Instead of running it through the SE inverter, I'm looking for a 3KWH battery solution that is bundled with an AC charger and 2000 watt inverter. What I want to do is charge off the AC from my SE inverter to use a battery back up solution during a power failure. I already have the SE Backup box installed with a critical loads panel so in a grid down scenario, if it is sunny, I have power most of the day. What I don't want are the solar generators as I don't need the solar charge controller and all the other whistles that make them so expensive. Anyone seen an "all in one" battery solution like that?
