Sorry, don’t really know that, as I didn’t tried, as I don’t have a MPPT RS…
But I know that in the case of Multi RS, the VE.Direct is only for configuration or connecting a GlobalLink 520…
Frankly I’m not very keen on switching to VE.Direct, especially when the manual doesn’t say that one should prefer one over the other. RJ45 cables are much cheaper tham VE.Direct, so I’m guessing most people with an MPPT RS are suffering from the same issue as me.
Initially I was also somehow irritated by the lack of this information… In the initial period when I’ve kept an eye on the system.
But once the annoyance dissipated and my focus was moved to other things I’ve realized that it’s not so important.
You have the VRM where you can see those info in a more intuitive and nice way.
Just set it to 7 days or 30 days and move the mouse over the graphs and voila: all info at a glance.
I don’t really care about the history either, I’d much rather see tracker specific breakdown like in VRM. But broken histogram is less useful than an empty card, especially since my MPPT thinks the day changes at 16:15 and there’s no way to fix that.
I believe some MPPTs doesn’t have an internal clock for knowing the time and even if they had, that could be a problem with keeping the correct time considering different timezones, sunrises and sunsets, etc. In the end they are used all over the world.
So no internal clock. Therefore the day change is based on “solar day”.
Meaning, after dark - meaning PV voltage below a certain level for a certain time - the day pointer is moved to the next memory location.
In your case, because the system has a clock, on Cerbo, the system sees that transition to the next day and mark the Cerbo’s time at that moment.
Which - Cerbo’s time - can be correct set or not…
But the MPPT could be used in an environment without Cerbo and must account for different days.
So the above mechanism, in order for VictronConnect to show you different values on different days.
My Cerbo has the correct time. I wouldn’t have a problem with the MPPT deciding on its own when the day ends if it would you know, work. PV voltage drops to as low as 25 volts but it still waits until 16:15 (the time I booted the unit for the first time) to change the day.
