It has happened to me a few times that the battery is not getting charged even if the PV Generation should be more then I consume if I have the export limit enabled.
What I have noticed is that if you have set the Export Power Limit to the same value as Battery Charging Start Power and then the PV generation slowly is rising to produce more then you consume it will just not start to charge the battery as you would expect it to do but instead it just starts to limit the PV Generation to stick to the Export Power Limit.
So even if the Export Power Limit and Battery Charging Start Power both are set to 0 this might happen.
I typically have the export limit enabled always and just change the Export Power Limit to a low value if the Spot Price goes negative so that I do not have to pay for the exported energy. So if the price is low for longer period you might run in to the situation above since the export limit was low from the day before and PV Generation is starting in the morning.
I have now started to use the following values, lets see if I run in to the no charging situation again.
Export Power Limit = 20W
Battery Charging Start Power = 10W
Has anyone else had a situation like what I have described above?
