Mack Pinnacle Wall outlets?

Might need to check under the bunk, or in a sidebox, for the inverter itself. On my Cascadia (I know, different animal altogether), I have to manually turn on the inverter every time I want to use it. Stupid part is, the truck won't idle more than 5mins. Useless feature.

 

On my Freightliner I have to run the APU to get any 110 power....No inverter,just a generator.
It has a Carrier APU on it..

It does run my 900 watt microwave,32 inch TV,laptop and everything else I have tried so far.

My last truck I had AC power with either the truck or the apu running...

 

It sounds similar to the Phillips setup that we have in our Volvo. I think the junction box had a 15 amp breaker in it, so you're looking at around 1800w for that if it's the same. It will more than likely be shared between all of them. If the cables they use are 14 gauge, you should be able to use all 1800 watts safely on one outlet if you needed to.

If your inverter is rated lower than that, use only that much total. Ours was broken when we got it, so we had a 2000 watt/4000 surge pure sine wave inverter that we rigged into it. We disconnected the old inverter and connected the new one to the battery. We then took an extension cord and replaced the female end with a male connector, creating a double male cord. This cord goes from the inverter, into the wall outlet that's connected to the breaker box. When we want to use shore power, we simply disconnect the end from the inverter and hook it into the cord that supplies power.

Our breaker box was under the seat in the bunk on the driver's side. The inverter was outside the truck underneath that area.

 

Being as Mack & Volvo are intertwined now, if you look under the bunk, or in the storage compartment access from the drivers side, you should see a factory installed inverter, a big one. Like 1800 watts. The on & off switch is probably under the bunk on the drivers side as well. They work great.

 

Ethos, I know this is off topic but how do you like the 2014 Mack Pinnacle?? I am considering buying a 2011 and I was hoping you give me your overall opinion. I really like the truck but I keep reading about DPF issues and how difficult it can be to manage. I will be doing short hauls. Thanks in advance.

 

If you are talking house power, at 120 volts and 15 amps.. this is very serious power. There should be a manual with your truck, check up on it's electrical section. Try to find out what it is you are dealing with exactly. Im going out on a limb and assuming that it has a APU big enough to feed it house power into the cab and sleeper. I hope it does.

This is a brave new world as far as Im concerned, Ive had a nice quality beef amp with lots of power on two outlets provided I can feed it plus the 4 batteries it was tied to and a monster alternator under the hood back in my day.

I had a portable 300 watt 120 volt inverter for up front to feed the laptop computer for GPS work etc. It never failed us. About 10 years later it finally burned through it's circut boards in our vehicle and burned, requiring disposal. It was a nice little inverter.

If at all possible have a protective strip or device on that 110 volt 15 amp outlets inside that sleeper. You never know if it's winter, you got wet pants or something trying to sleep rolling up against that thing. Short something out right quick. (That would not be good.)
