I have a Victron Multiplus 48/8000 (3xMultiplus in 3 phase) with a Cerbo GX.
This now runs on firmware v3.50~24 (beta). The VRM beta portal is also used.
An error occurred a few versions ago. (about 2 weeks ago??) The consumption from the grid is displayed much too high. For today 24-09-2024 the last hour (6:00 PM to 7:00 PM) this is 212.23 Kwh. According to P1 monitor this is 0.023 Kwh. What could be wrong?
It’s not just today but for a few weeks that this hasn’t been properly represented. Just given this date and time as an example. To date, it has not been good.
On the stable vrm branch there are at least 2 persons (me and another) that have absolutely wrong values in consumption. During daytime it closely follows battery charge, not power use. At night it just shows almost nothing.
However in the betavrm all the numbers seems lower.
What I think happens is that for your specific setup a “logical” point of view for your consumption is chosen. In the betavrm it has been rechosen, and it turns out to be wrong in your case.
So rather just a bug with the betavrm, I think it is a generic bug with vrm, but because of the beta, it allows other formulas/datasets to be chosen as consumption.
Hi, I have reinstalled and configured my Cerbo GX, with no results. I then use the standard VRM again and reset the CerboGX firmware from beta to standard (Firmware V3.42). Unfortunately without results. I still see values of over 250 kWh. For example, between 6:00 PM and 6:59 PM. The battery is at 30% (minimum charge status, unless the grid goes out). The deviation increases as I use more power.
The system consists of 3x Multiplus 48/8000 3 phase. The main connection is 3x 25A. So I can effectively use 17.2kWh. The battery has a capacity of 92kW. But it is not used. (at 30%, minimum charge status, unless the mains goes out)
All consumers are on AC out2 (critical load). But this has always been the case. And has always worked well in the recent past. and calculated with correct values.
