  • 12v System

    Hello Prado People

    I'm looking at putting in a 12v system into my 150 GXL and wanted your thoughts on the RedArc Manager30 system and display unit. Are these any good and can someone recommend another system to use??

    I am wanting to run the following
    69L Coolman fridge
    External side lights (for when camping)
    USB Charging
    Laptop charging
    Air Compressor

    and wanted Solar input and maybe AC-DC charging when not in use

    Thoughts on what's good??

    Thanks

    Jeff

    Hi Jeff. Now on my second 150 series GXL and have gone about Aux battery differently this time. First time was in 2012 model using AGM under the bonnet and monitoring of that was via simple voltmeter, one in the overhead console and another in the cargo bay. Easy enough to see battery level based on voltage. If we got down to 12v it was time to ensure charging soon, via solar or running the car.

    In the new car (2021) I have set it up differently due to going with LiFePO4 battery for the Aux. Mounting the battery was the first big challenge. Now that is sorted I have this week added Victron BMV-712 monitor. While I managed to get a relatively cheap battery and DCDC charger, I went the other way with the monitor. Figured we’ll have the car for many years and if we look after the Aux battery maybe it will last. Thus far the BMV-712 seems brilliant. I like that you can see how many Ah you have used via bluetooth, and the app is simple yet highly functional.

    Fridge has been on since mid-morning yesterday, battery now at 85%

    What was it about the Redarc system that grabbed your attention?

      Hi Wazza2, I'd be very intersted to hear more details about your setup and in particular the battery location as I'm planning a cargo mounted battery at the moment (primarily for a fridge).

        I have a 2016 with a plain old deep cycle battery under the bonnet with heavy cable to rear for battery, all accessories and power to camper trailer. All controlled by a simple VSR. Has worked well for nearly 6 years BUT if I was setting up a new car for long term ownership I would certainly go down the lithium pathway with a removeable battery in the rear. Much lighter, smaller and probably similar price over the longer term with longer lasting more powerful batteries. Worth investigating as the technology is changing rapidly.

          Hi Jeff. I have the Redarc Manager 30 in my prado and it works fine. The one advantage I can see over a Redarc BCDC (solar capable) charger is that it can connect to 240v shore power. The downside is the extra space and cost. My partner likes the idea of hooking up to a powered site when we are in the occasional caravan park so I stumped up the extra $$$. Once the cables are connected it is about 450mm long, so you need to plan where to put it in your vehicle. We could have gotten away with a Redarc BCDC25 or 40D unit if we only wanted to charge the battery using the engine or solar blanket and saved some space. I have the BMS hooked up to an Amptron 150kwh lithium battery via the Egon DC Hub (another pricy option, but I'm no auto sparky and it made my life very easy).

          The DC hub connects the BMS 30 to the fridge, USB ports, 12v cigi ports, and the Redarc 350W inverter. I haven't hooked up my compressor to the system as I use the crank battery under the hood, although I probably could easily enough. The BMS 30 is quality gear and I expect many hundreds of thousands of km out of it. The lithium charges quickly and runs a single Engel 40L fridge for at least three days without solar or engine input. We'll be adding a second fridge for our upcoming Top End/Kimberly/Pilbara trip and I'm sure the BMS 30 will cope no problem. The display is old school, but it works fine and is all you need. You can see your state of charge within a few button presses, the Redvision display is just overkill. I've read good things about the Victron gear, but I had a preference for Redarc. Cheers
