I have a Multiplus II 48/5000/70-50 and a Cerbo GX amongst other stuff.
I have set the AC input current limit to 4 Amps.
And so if it is charging easily, it sticks to the 4 amps.
But when there is a load on the system, which is greater than 4 amps, it just almost takes 6 Amps (5.6 Amps). Viewing the Multiplus through the Cerbo GX shows an input current limit that cannot be set lower than 6 amps. The loads can be much greater than the 6 amps, and the battery can easily deliver all the power, so the system and its power assist function work fine. But why does it exceed the 4 amps?
I also tried disabling the "overruled by remote" in VEConfigure3 on the multiplus file. This should block the Cerbo GX from messing with it.
I didn't do any ESS configuration on it, which I will at some point in near future.
However, for now it is just a semi-offgrid system which needs to stick to the 4 amps if grid power is available. And if the grid power is available it works in power assisting mode.
