Having a strange issue on a new install, which is identical to a couple of others.
With ESS optimised mode the solar yield was terrible, the inverter was pulling most power from the grid. I changed the modes to "keep batteries charged" and immediately the MPPT started delivering power. Change it back and the power drops significantly and reverts back to mainly grid.
I have compared settings and can't find a difference.
475 firmware on a 3kva multi and 2.57 Venus OS, mppt is on 1.50.
