Hello,
Been having some trouble with a Victron system that is Grid Connected and the batteries not wanting to discharge to the house loads. We have 6 x Fogstar Batteries, Multi RS Solar with AC connected to AC-IN, and a MPPT RS with 2 strings of PV connected to it. These all connect to a Cerbo GX and all devices are found on the CGX, we have a Meter installed which is the VM-3P75CT.
The CGX Reads Grid and AC Loads, the batteries read on the CGX and the Solar too, but the batteries and PV for whatever reason does not discharge to the house loads, the battery will force charge from the Grid when set to charge batteries fine but once turned back to Optimized with battery life it goes back to idle and doesn’t discharge to the loads.
We recently went back to do some more tests and connected a Load to the AC-Out-1 port of the RS inverter, turning on a Toaster the batteries and PV instantly started discharging to cover that load which showed on the CGX as it should do, but once we turned this off the batteries stopped discharging to that “Critical Load” section and went back to being Idle.
If anyone could help out or suggest some things that may be the issue that would be great as getting no where with this, Batteries have been checked several times and have Discharging and Charging enabled, and we have proven that the batteries will discharge with that Internal AC-OUT load. Could this be an issue with the Victron Meter we are using? DESPITE the batteries force charging from the Grid, just for whatever reason we cannot get the batteries to discharge to the AC Load.
