I'm considering a pair of these. They come with shunts and are 12/24v and they are relatively inexpensive. One for each side of the 260A alternator. My main need beyond monitoring the draw on the stupidly expensive alternator is to ascertain how much overhead I have to work with on the 24v side to choose appropriate size and quantity of Victron Orion-Tr DC/DC Converters for charging my habitat solar bank.
My only concern is that the specs given by Niehoff do say the alt can produce "28 V 260 A/14 V 140 A" which the 14v side is well within the capability of the gauge.... but if the 24v side can actually push 260A...... of course the LBCD would shut the truck batteries down if it senses more than 200A going through it..... the gauge could easily max out though I'm not sure that would be all that big of a deal since I probably want to keep the output below 150a even with the DC/DC converters in play. The ones I'm looking at can supply 17a each to the habitat batteries and I'm thinking of 2 or 3 of these in parallel.....
Anyone know what the 24v side on these trucks is nominally pushing for amperage on a C7 truck with fully charged truck batteries? My 1079 does have a bunch of 24v lighting around the outside (it's not 12v like the truck lighting) of the habitat but it's all LED. I know the older trucks even some with C7's had the 100a alt so I can't imagine I don't have the overhead needed to run a couple converters at 34a to charge the solar bank while driving.
Or if anyone has suggestions for better gauges......
