MPPT todays data Issue?

Hi Guys,

actually i monitored MPPT data to create some Node Red analysis. Due to this i noticed that todays data of e.g. Yield, Max Charge Power a.s.o. is only working right partially. It looks like the data is correctly showed when PV Power is active but if PV power is gone all values showing 0. Checking the same data via Victron Connect Remote shows the same result. Can someone out there confirm my observation? If yes, works it as designed or is this a bug?

Thanks for help and comments

MPPT 250/100 VE.Can firmware v3.11. I don't seem to have this issue accessing via VRM (not local, so I can't check BT):

thanks for your answer. Just noticed: the issue happens depending on day time and not on status. Have checked the values at 9:30 pm and they are all 0. Will investigate the exact behavior tomorrow.

Looks like MPPT History used wrong time/date. Yesterday's History showed values of today.

Ideas?

I wouldn't presume it has an accurate internal clock. I would expect "days" are based on PV activity: PV voltage detected = sunrise. PV voltage to near zero = sunset.


I'd like to think it possibly has an internal timer to prevent false "day" counts if PV is disconnected.


If it doesn't have some kind of timer in place, PV disconnects and restarts of a certain duration might falsely trigger a new day.


Just guessing.
