Hi, I have a customer with an older LG RESU 6.4EX, they are now discontinued. This battery is brand new unopened. I have a list of compatible inverters and the 48/3000 Phoenix is one of them. I am trying to set it up as an off grid system for my customer. I want to know if anyone has any experience with this battery and its firmware, and its compatibility with the 48v Phoenix. I have no idea if this battery is able to be wired directly to an MPPT charge controller either and if that is a possibility, it believe all of the newer RESU batteries require a grid connection to function properly.
Any help/suggestions would be greatly appreciated!
