Just happened to notice this. Sunny day, topped off early, got a little cloudy and started using battery for a little while. Clouds cleared and the batteries appear to be charging again but the BMS charge is still showing forbidden?
Anything to be worried about?
Is that a screen shot from the front of your controller? If yes, perhaps since your batteries are at 100% your (BMS?) required charge is not needed?
@frugal-farmer It is a snip from the web monitor. Maybe just a time lag issue or something.
Typically, when the batteries reach 100%, you will see "BMS Charge Forbidden," indicating that the battery is no longer accepting a charge.
Do you recall if the battery was at 100% when this message appeared? It looks like the batteries are full on the screenshot. This is normal.
@eric The batteries did reach 100%, but the arrow direction shows from inverter to battery and 90W going into battery while forbidden is set.
@joel-brodeur I believe this is normal. Since the battery is already at 100%, it likely wouldn’t be considered charging. Instead, it’s more of a maintenance state to keep the battery fully charged, which is why it’s only drawing a small amount of power. However, I will double check on this.
@eric Sounds good, thank you sir. That is what I was thinking but wanted to make sure nothing broke.
Thanks again.
