Dear Forum
I could see plot and history of battery-voltage in the graph under my display in the VRM-screen and valued that very much. I updated today my MPPT 70/15 to latest firmware and noticed afterwards that the voltage trendlines disappeared in the graph as of today. In yesterdays graph the voltagelines are still displayed… The actual voltages as momentary values are still presented in the overview/picture of the system. Anybody an idea? thanks in advance.
Hi @JanVer
There’s couple of things need clarifying here, so just guessing…
You say 70/15, but that’s a very old model, replaced by the 75/15.
And that chart you show is normally populated by a blue line of State Of Charge (SOC) rather than Voltage.
Can you confirm? If all is as you say, you may need to try to revert the fw to return to what you had.
Thanks John, it is the 75/15 indeed. Sorry for the misinformation. But the voltagelines are back from holiday starting today…!? I have a homebattery with Overkill BMS that is not communicating with Victron unfortunately so must import it in the system somehow over Arduino or so. But that is why I need the voltages as a minimum. Thanks again and regards
