I am just a noob, but I think you need a charge controller and an inverter.

Looks like it might be time to actually pull the trigger on one of these. I can't see them getting much cheaper.

I have two but only one works with Overkill app. I think the newer batteries come with the BMS from another brand which does not work with the Overkill app, and I'll have to stop discharging around 5% left because the BMS presets the under voltage protection too low @ 2.4v which may permanently damage the battery cells.
