I have a backup system consisting of:
- MultiPlus II 48/5000/70-50
- Cerbo GX
- BSL Battery (B-LFP48-135E) - connected to GX
System is up and running.
My experience is limited, but I have a concern - the MultiPlus stays on "Absorption" even though the battery is charged to 100%. Been like this for several days now. Is this normal? To confirm, grid is on and load is less than 1KVA.
Also seeing the Inverter LED on the MultiPlus come on from time to time.
I'll try to upload video soon.
