Hello, I have a problem with the values on the VRM
old configuration:
Octo GX
3-phase MPII 3000/48
Battery, 12kwh lifepo4
MPPT 150/60 2.4kwp
MPPT 150/45 2.6kwp
MPPT150/35 2.1kwp
SYMO 4.5 at output; 4.5kwp communication sunspec ok
SYMO 6 at input; 7.36kwp communication sunpsec ok
Measurement by external current transformers to MPII on the supply from the grid.
Everything works ok, measurements ok, values on VRM ok.
New configuration.
Octo GX
3-phase MPII 3000/48
energy meter VM3P-75CT on the supply from the grid
Battery, 12kwh lifepo4
MPPT 150/60 2.4kwp
SYMO 4.5 at output; 4.5kwp communication sunspec ok
SYMO 6 at input; 7.36kwp communication sunspec ok
SUN200-12KTL-M2 + ET340 at input; 12.9kWp
In the ESS, the "external meter" measurement, the position (input, output) of the PV inverters are set correctly, and the electrical connections are also correct.
It works fine in the remote console. on VRM "realtime" values OK.
But total production and consumption are absolute nonsense.
in the picture the production is 107kwh, but the real production is 74kwh at that time. Consumption is also bad. During production, it shows a consumption of around 5kwh per hour, which is also nonsense. I sit with it all day, looking at the consumption. For an hour the consumption is 700W+-200W, everything looks ok and in that hour the VRM shows me a consumption of 5kwh.
Since the configuration change it shows this nonsense and destroys my data. Tried factory reset OCTO GX, reload ESS.
I'm constantly checking everything, but I'm running out of ideas on what to do with it.
Can anyone advise?
thank you very much
Pavel
