Modern tech for eAPUs.

Ive parked next to a couple guys with the opti idle or whatever it is.. Seems kind of annoying to have the truck shake every time it starts then rev up rpms then shut down again..

Me personally I enjoyed my apu when I had one, although I found it quite difficult to sleep in the summer with the A/c because the apu is so loud... and it would bog down every time. The a/c clutch would kick in..

Ive enjoyed reading about a couple members on here that have the electric setup with batteries, I think it was @Siinman and I forget who else. They seemed to like it so far

 

Love my set up for what it is. I still need to change the EPU batteries at some point because they are still the original batteries. Once they die out I will put lithium in them or buy two more starting batteries like I have now that are lithium. This system works great unless out in the desert and over 100 with sun beating down. It cannot keep up in that kind of heat to my liking. I like to be around 68 degrees when I sleep or colder if I can.

 

I drove freighter with their electric a/c it was ok. The problem was it could only go about 10 hours. Plus it only cooled the sleep and doing that in summer daylight it not big enough. The way it was wired the low voltage cutoff for the A/C could cut off before the computer monitoring the batteries would auto the engine to recharge them.

The new Volvo truck system that seems to have electric fans by radiator and can cool the sleeper and front of cab using the same system as driving plus it 24 volts truck. Sounds like a better setup.

 

I think you meant me. And its alright. But im reserveing judgment till i get the solar pannels on. Right now with it being 100+ out it mercs the battery dead in about 6 to 7 hours then i gotta idle 6 to 8 to charge it for another go and thats at 76 degrees. I mean i at best get 3 to 4 hours of charge if i watch a movie on my laptop or something in addition to cooling or 4 to 5 if i drop the temp to 72ish. So far i am actully idleing almost as much as before i got the system especially on my 34. I am sleeping better so there is that, but im likely going to either need to double the 400AH to 800AH or get a gas generator for extreme temps which is fine. But as is...im not impressed.

 

@Arctic_fox just put a nice apu in , maybe he'll stop in post a picture or two. Oops oxbowed , nvrmind lol.

 

Lol ask and ye shall recieve. Like i said though i only have half the system so until i have the whole thing i am reserveing final judgment. But just batterys....i am not impressed. The whole point of an APU is less idleing. Not as much or more. And if the solar means i only run need to run a genny in extreme heat or a couple of hours of idle that is acceptable. But im going from 100% to 0% in like i said 6 hours MAX ive been averageing around 4 and a half to 5 since 76 is too hot to sleep well even with a fan though i can relax in it and be alright. 72 is about the max i can tolerate for good sleep and 70ish is my ideal.

 

I wonder if a couple small vertical wind turbines would help 150 watt each . Mount a pole with a lockslide put it up when stopped and lower n lock when moving , just a thought .
