I have a question. My system has been running near perfectly the past week.. Yesterday I installed a ET112 in line with my grid feed.. Now I have some issues. I assume it is setup related...
Multiplus2, VenusGX, MPPT150/100, 2xPylontech US3000, ET112
three loads: mains in to ET112. Then after ET112 I have loads. Geyser and some plugs. Then AC goes to inverter. coming back from inverter I have more loads on the Critical load side. Before this it was set up the same without the ET112
What happened before the ET112. Excess power from MPPT would be fed back into the grid and as a result could be re-used by the geyser and plugs directly after mains.
What happens currently is that my MPPT and battery is being used to supplement power to the load on the mains. This is a big issue as my battery runs flat in no time. I want the battery only to be used for critical loads and if no MPPT is available then loads off mains must use mains and not battery power.
Can anyone help?
