Power hungry vans (1 Viewer)

[Ivory55]

with the vans becoming more power hungry do any of the big vans have double alternators fitted yet. I know they fit them on ice cream vans etc just wondered if they were used at all.

I was of the impression that vans were becoming less power hungry.
LED lights alone have led to power savings that were unimaginable just a few years ago.

Well there seems to be a lot of talk of generator and mega watt solar panels it must be powering something.

Never seen that but a lot of German vans Hymer, Carthago etc., fit uprated alternators 160/180 amp.

Most vans on truck chassis will have two alternators as the chassis runs at 24v and the habitation side runs 12v, some other vans with big battery banks or inverter driven habitation air con for use while travelling just make do with one bigger alternator and a booster to make it work hard and I guess get around smart alternator problems.

Some manufacturers are now fitting compressor fridges and only one leisure battery. My van as the same so I fitted extra battery and 200 watt of solar I also need power for my CPAP machine and humidifier.

That’s a lot , I thought 18amp was the normal for most fiat’s

My RV has 180amp alt . that seems to cope with 2x 170 ah chassis batteries and 4x 6v 225amp hab batteries .

Big output alternators are used no stop - start vehicles and those with regenerative braking. Certainly on current VW T6 and New Crafter and I suspect that Mercedes Sprinter and probably PSA Peugeot Citroën and Fiat variants are similar.

Ok I can see how a larger output Alternator is useful for mohos, maybe even two, one for cab batts, one for leisure batts, but at what cost in terms of engine drag and fuel economy?, and hopefully even with two alternators they will be the "Smart" variety that know when there is no charging current demand, but even ordinary ones know that AFIA, wish I knew what was smart about alternators on a moho with no stop start etc.
I am still trying to find that elusive Fiat DRS switch,for the rear wing/spoiler, I know its there somewhere as the sales rep at The NEC told me so.
