What is "AC load" in an ESS config with 3phases with critical loads connected only?

Hi,

I am running an ESS config with 3x MP2 5k and SmartSolar 450/200 inc LiIon battery pack 22 kWh.

All running fine so far, but I don't know what means AC Loads, because all loads (whole house) are connected as critical loads, nothing before the MP2s. Any idea?ac-loads.png

That is for loads in front of/parallel to the inverter, measured via a meter. The inverter backfeeds to supply them.

If you don't have any, untick the "has AC loads" option under the meter selection in ESS settings on the GX.

thanks for your fast response, however this would be great, but I couldn`t find the „has AC loads“ option, „AC-Output enabled“ removes my „critical loads“ output and shows AC loads only.

Other option is the energy-meter options in ESS menu as shown in the screenshot, where AC meter or Netmeter ca be selected, none of the with the „has AC loads“ option

Could you send me a screenshot of this setting please?

My bad, mixed wording with DC loads. Need more coffee :)

Disable inverter AC output in use.
