Is it possible to charge a GroWatt SPF 3000ES via grid power while the inverter is actively being used? So far, with any combination of settings I've tried, the only way that the inverter will charge via grid power is if it has been switched "Off"
I can't figure out if this is a settings issue, firmware/hardware limitation or user error.
Andy P on youtube with a Growatt LVM 3000 says that he's able to grid charge while using the inverter to prevent overnight battery drain. It's in the comments for the video as a response to Paul Wittman 11 months ago: Growatt LVM 3000 watt Inverter Overview

. . . you can set it to SBU so it will run on solar and battery as long as your above your set voltage and transfer voltage and then if you choose the CSO under option fourteen, it will charge from the grid under CSO once there is no solar available and your battery is not full. . . . if you set it to just enough amps to keep things from going flat . . . you would be putting just about what you draw back into the battery. . . set the utility charger amperage to just barely enough for your overnight loads and your transfer back to the grid voltage at a voltage a voltage equal to say 20-30% remaining. Set it to CSO so it starts charging from utility once the sun goes down but at a very low rate to keep things topped off. That should leave your batteries close to the transfer back to the grid voltage but still on battery overnight. And leave most of the capacity to be available for solar to charge them up come daytime.
The goal being to maximize the amount of power you draw from solar either charging your batteries or running your loads.
