Battery current monitoring?

[stevemitchell]

My NMEA 2000 network has PGNs flying around on it for battery information for my various battery banks, including current draw. On the other three major MFD brands, I've configured a display item to show this while underway so I know if there is a problem - too much current flowing out because of some pump running, or the charge current coming in from the alternators, etc. It is a great safety feature.

I can't find any way in TZT2 to configure this - only battery voltage, and that seems like it might be coming from somewhere other than NMEA 2000.

Specifically, I believe it is PGN 127508 that I'm looking to display on the TZT2.

Thanks!

Page 2-11 of the installation manual, section 2.7.4 lists the input PGNs - PGN 127504 is not on there.

Thanks. I hadn't found that.

I guess now it is time to ask if this could be added both as a supported PGN, and an object/property/data that can be displayed on a dashboard. As far as I can tell with all of the other units I have on board, Furuno is the only MFD that won't display this. It would be great to have from a visibility perspective.

Product development has sent the request to Japan. Hopefully the suggestion will be accepted.

Thanks very much! I hope they do too, but just having folks like yourself, and a great company like Furuno, listen to their users, is a nice change from many other companies out there.

Are you saying the other brands do have this capability?

Ive been wondering the same thing. Companies like Victron and Blueseas have voltage/ameters for separate display but I have to imagine this would not be too tough to integrate w current MFD's as an internal function.

Def valuable data to have on hand

The relevant NMEA 2000 PGNs are 127506 and 127508 for DC voltage and current data. Neither one is on the list of supported PGNs for the Furuno MFDs or even for the FI-70 instrument display so far as I can determine.

On my old boat, which had a TZT 2 system, I had a Garmin GMI-10 instrument display. That did support the DC voltage and current PGNs.

All of the other major MFD brands support displaying battery voltage, DC system current, and some have wattage. Similar to having fuel tank & water tank values at the helm, it is very important to see current battery status especially when underway.
