I saw in another older thread about state of charge. I don't know if it is a technical limitation with the EG4 inverter firmware within or a sourcing of firmware update but SOC to me a game changer.
Right now using ECOFLOW Smart Home Panel 2 with their delta pro ultra and battery. Their smart panel app is able to set a reserve of x% to hold in the event the grid power shut off to activate an emergency power of the battery. This seems like would be a no brainer feature for prolonging the life of the battery and having emergency battery.
I mention this as I'm looking to setup a EG4 inverter for another place instead of using Ecoflow.
