Suggestion Tracking Grid Usage

Solar2025 · 2026-08-15T00:09:51Z

I have a basic setup - EG4 18KPV and 280AH battery plus some solar capacity. My Grid connected breaker panel is connected to the 18KPV Grid input and important loads are tied into a secondary breaker panel and connected to the 18KPV Load output. My CTs are connected as recommended - between my utility meter and my main grid connected panel. I am running Self consumption mode with Off-Grid mode enabled. I do NOT Sell back to my utility. My large and non-critical loads are connected to my grid connected breaker panel and always use utility/grid energy. The monitor program shows power from Solar and/or Battery going to my Backup Power(EPS) output with zero power coming from the Grid (to feed important "load" outputs). I would like the EG4 monitor program to also track energy consumed by non-important loads as fed from the grid that is occurring at the same time. The CTs are connected and could monitor this grid usage. I looked "Data Usage" hoping CT power was tracked, but it is not. Maybe it is recorded somewhere and someone can help me find it. I believe that it could track grid consumption because, when I run low on battery, my 18KPV inverter switches over to feed important loads from the grid input and during that time the monitor program records and plots ALL energy consumed as read at CTs - both important loads and grid-only connected loads. I hope I have explained this clearly. Peter

@solar2025 I am in the exact same boat as you , no sell back with PG&E. I have seen few spikes here and there on the monitor that looks like it pushes and pulls a few hundred watts now and then. I now believe that is the system misreading usage and not actually feeding the grid. The CT's are much larger than my service feed , so I chalk up these spikes here and there as inaccuracies .

You are correct though , off grid does insure that you never feed the grid.
