I currently have a grid tied system with a ECOFLOW EF-PCS-24 OCEAN PRO [240V], what's the cheapest way for me to upgrade so i can use my panels when the grid is down?
Not too concerned about having enough battery to run the whole house for an extended period, but if its daytime and I'm waiting on power to be restored, it would be nice if i could actually use what is being produced currently by the panels to keep my fridge/freezer/necessities up and running.
