I recently got my hands on an EG4 12000XP and EG4 48v 100AH LL-S 5kWh setup. I am planning to build out 2kw of solar initially and eventually ~8kw over the year as I can source second hand panels. Currently I am charging my EV with L2 240v 50a socket drawing from the grid, but my charger lets me set different charge speeds which I have set to 7.6kw atm. What I would like to accomplish is this behavior:
- EV charging during the night is just AC line power from the grid (doesnt discharge the LL-S deeply)
- During the day it uses as much wattage as the solar is putting out without drawing any from AC line power.
- OR
- During the day it uses max wattage from solar and then augments AC line power to meet load demand
Given the 5kWh battery is barely only a couple % of the EVs total capacity I have it here more just to make the system stable as a buffer between the solar and EV but I dont want to deeply discharge the LL-S several times a day to charge the EV and murder its lifespan. Is there a config on the 12000XP that gets me close to any of this? Would a smarter L2 charger be able to dynamically adjust its load to match the solar performance in scheduled windows or is this all impossible with off the shelf stuffs and I need to build something rather DIY? Can I use the "smart" load channel and an ATS maybe?
