I’m wondering why there is no charger output disable on the Blue smart IP22 charger Bluetooth interface? I suspect the existing hardware should support this.
I have the IP22 hard wired into a camper system with Victron smart MPPT solar and Orion XS DC-DC chargers, both of which do have charger disable control. The IP22 is on an existing shared circuit so can’t be individually powered down that easily.
I think being able to turn the IP22 output off while the rest of a system remains connected to the mains supply would a be a simple option to aid battery maintenance activities.
