An MFD’s source selector would wrongly list the charger as a battery. First, charger output voltage is NOT equal to the battery voltage and charger current is NOT the overall battery current. However, an MFD could correctly list the MPPT if the PGN’s type field would be “Converter” (or maybe there are newer types available by now that come even closer)
You have type (0) which is battery indeed, but, from what I’m seeing, they are also broadcasting the type (3), which is Solar Cell (or MPPT).
In my case, on 127506, I have three devices: one type (0), a battery, and two type (3), solar cells, because I have a MultiRS with 2 trackers.
All of them, of course, with different instances.
yes, the other instance with type 3 is for the solar panel side (input), that’s fine, but the battery-type instance is the problematic one. for a complete charger display, both are needed
So you don’t have both? 0 and 3?
Which are the components of your system?
And what do you have broadcasted on 127506?
I probably haven’t made my point very clear. Of course, a DIY geek with all this info can get the info out of the PGNs, but a generic MFD that should be able to display data of hundreds of different devices will fail unless it has a huge database with exceptions and particularities for half of these. That’s why there are communication standards. Unfortunately, the PGNs for DC and AC power devices are not very good, but when used consistently, they should do.
We are developing new marine MFDs with the aim to show more data than existing ones, for instance including a proper MPPT display with data of the input (solar) side and the output side. But the output side of the current VE.Can MPPTs would be falsely picked up as a battery monitor.
Are you from Victron?
I see your angle now…
Nope, just a geek.
