Battery capacity in VRM wrong while SOC and consumption correct

[juergen]

Dear community,

I have an installation with Cerbo-GX, 3 MP2, Lynx Shunt, multiple LiFePo4 batteries behind it (total approx. 1200Ah/60kWh).

While the real-time data is correct incl. the SOC, remaining battery time, comsumption, etc., the graph with the (e.g.) daily data of my installation shows on the y-axis a random battery capacity of somewhere between 5kWh and 15kWh (can change by day), while the right hand side with the battery SOC in percent is correct. See here:

I have entered the correct values of the battery capacity in Ah in the Lynx Shunt settings within the console, and the MP2 settings for each of the 3 phases as battery capacity. The Lynx Shunt is used for the battery measurement, no battery BMS connected.

What could be the reason for this behavior and how could I fix it?

Thanks! Juergen

Das “Jetzt” bringt mich einfach darauf “deutsch” zu antworten

Die linke Achse hat nichts mit deiner Batterieleistung zu tun … es stellt nur die “Energiemenge” in kwh dar … die du zb. verbraucht hast … oder Solarertrag … Generator etc.

Ah - verstanden. Danke sehr!
