Dead space behind oven? larger converter wires to Batt?

1. I am installing an inverter and I've been looking behind the cabinets etc to find someplace to put it. I've discovered a large area behind the battery box (from the outside) and behind the oven (from the inside). In a truck camper this seems like a lot of wasted space, seems they could have made a bigger battery box so I could fit larger batteries or put in a second outside door to use this space.

Is this dead space required behind the oven for heat dissipation?

2. As part of the install I am running large wire to the inverter, I've noticed that the factory wire between the converter and the batteries is quite small, looks to be 10 gauge.

Would I gain anything by upgrading this to larger wire? Don't seem to be having any problems with it charging the batteries. It's a Progressive Dynamics 4000 series with built in charge wizard.

    Probably a voltage drop calculator would be more appropriate.
  • I installed my 1750W inverter under the countertop on the side of the sink.
    My camper with big countertop has a space under that could fit small person, what manufacturer used for making 3 foot dia wire loops.
    Space behind the oven might be good if you are not using the oven, but inverters under the load need really good cooling.
    10ga wire in household application can carry 30 amp, but 10ga standard jump cables are rated for 200 amp.
    All depends on application, but for inverter you want to minimize the voltage drop.
  • My questions have nothing to do with the inverter, just a couple things I found while installing it.

    Just seemed like the 10gauge wire was pretty small to go between the converter and the batteries.

    Inverter size/power?


    It's a 1000w but I'll be running dedicated 2 gauge cables to the inverter.

    I was just considering upgrading the wires to the converter at the same time.
  • On same subject I just installed a 350w inverter I had laying around until I get a better one.
    I used 40" of #6 wire. How big of an inverter can I run on this wire?

    Yep.
  • I would turn the oven on and check the temperature in that area before installing something. See how warm it gets there.
