Why does "Limit Inverter Power" work, but "Limit Charge Power" does not in ESS?

I am running a MultiPlus with ESS Assistant installed. I had charge current set to max in VEConfigure, but had Limit Charge Power turned on in ESS, along with Limit Inverter Power.


This had been working just fine until I had to remove the BMV-712 temporarily. When I did this, I turned on the Battery Monitor option in VEConfig for the MultiPlus. I set the Battery Monitor in Venus OS in System Setup to the MultiPlus. However, now whenever charging occurs, it is at the maximum current, not what I have set Limit Charge Power to. Can anyone explain why this does not work with the MultiPlus Battery Monitor, but Limit Inverter Power does?

Hi @ee21

Do you have 'feed-in excess solar power' enabled?

if so: this sets the MPPT's to produce full power, and the inverter(s) will only feed-in when charge voltage is reached.
