I have an off-grid solar system consisting of two 550W solar panels, a SMARTSOLAR MPPT 100/30 controller, a MULTIPLUS 24/800/16-16 230 V inverter and a CERBO-S GX, and I cannot configure it so that, whenever there is enough voltage in the solar panels to power the loads, the power supply to the loads is done primarily by the generation or that the AC input of the inverter is turned off. From what I have researched, this configuration could only be done through Note-Red. Can someone help me?
When you are offgrid, there is no way to control where the solar goes really unless you are loadshedding loads based on what you have.
If you are conditional connecting to grid that is a little different. There are several ways to do that.
If you aren’t familiar with node red, then load the ess assistant and use sheduled charge in the ess menu, there you can set what pv and battery do in different time windows throughout the day. (You will remain grid connected but draw small amounts based kn whatvyou set in the charge windows)
