I am looking for a system that is capable of the following but the installers in the area claim there is no such system. But sights like Anker seem to tout their systems as capable of doing what I want.
I am looking for a system with around 15 x 400W panels, battery system with around 10k to 15kWh of storage, a panel for auto switching for a power outage and a generator port to charge the batteries in case solar and grid are insufficient. The generator does not need to automatically kick in but I want the option to run it and change the batteries in an outage.
The system would be designed to use the solar to get the batteries up to 100% then offset the grid in normal operation. Batt
