Ess using grid not mppt power

I have a system that is pulling half the available PV for AC loads and is preferring to use grid when in either optimised modes.

Batteries are charged, no limits hit.

If i change to keep batteries charged then all the power needed for ac loads comes from PV.

Swapping between modes shows the change consistently.

The ESS inverter limit was set which doesn’t just limit the battery discharge power but also how much PV will be used for AC loads during the scheduled charge window.

These two limits really should be separate, will log a feature request.

As I understand it the DVCC DCL discharge current limit is the current limit from the battery which is separate to the inverter power limit which is separate to the overall current on AC limit on the control panel.
