Haha. No, this is at a little holiday shack I own in the NW.
As you pointed out, there is nowhere to set the load limit from drid.
Problamatic when you run a generator even though it states max generator power.
I connected the grid supply to the generator input, limited it to 1100W, and tested.
It easily exceeded this limit on total consumption, charge plus demand.
This setting only limits the total charge energy from the generator.
The usage id not taken into account.
