Hi, we set up a MultiPlus II and Cerbo GX recently, and so far it works like a charm. The Victron components really make a professional impression.
Our setup:
- 3-phase from grid
- ictron MultiPlus II 12/3000, AC Input connected to sub-distribution L1 (single phase)
- 12x CALB CA180F 180 Ah LiFePO4 cells (from a stripped SolarWorld battery)
- 3x Daly SmartBMS
- Victron Cerbo GX
- Energy meter ET340 as grid meter, input connected to grid only and output connected to sub-distribution
- Kostal Piko 7.5, connected to sub-distribution L1, L2, L3 (SolarWorld-branded)
- Connected to Cerbo GX via plugin (https://github.com/schenlap/venus_kostal_pico - this was really easy to set up!)
So basically we replaced out-of-support components from SolarWorld OEMs by Victron components.
...did all the configuration and stuff, and that's how the topology looks like in VRM:
This is correct and all the numbers show up correctly, the system regulates like a charm (not discharging here because ESS minimum SOC is set to 35 % at the moment for safety reasons).
But, of course not everything is perfect yet :-) The VRM portal history data does not really make sense:
In the highlighted area for example, there was almost no consumption from grid, it was all covered by the MultiPlus. But most of the consumption shows up as grid consumption and only a few as battery consumption?!
The advanced statistics look all correct though:
It seems like just the historical data is miscalculated. How can we fix that?
Thanks very much for any hints and ideas!
