    Jip, and I love the real-time status. At that moment the system was breaking even and the battery only received charging current when the fridges switched off. Wet towels over the fridges and parking in the shade helped quite a bit..

    That is seriously cool. I see those meters are sold by 4x4direct but wondered if it would not draw unnecessary power. I assume the switches you have there are to switch the meters on and off.

    Will the meter reduce the current supplied to and from the battery? I assume the meter has to be connected in line?

    Yes the switces are to switch off the meters when not required.
    The meters themselves have low consumption and I think the light in the switch itself draws more current.
    The meters all have shunts and are connected in line 'sort of'.
    It was quite a mission to safely wire up this system. The shunts are quite bulky. There may be other meters with less wiring required.

    You could also use watt meters
    really easy to setup , no shunts to fiddle with
    Pos and Neg in an out, also fairly accurate in my tests

    Name:  BATTERY SETUP.jpg
Views: 334
Size:  65.4 KB

    Ok so I have a new bakkie and need to install a new dual battery system.

    So I bought a HCDP 30amp 12v dual charger with which I want to charge 2 x 100ah deep cycle batteries.

    Above is a simple (bad) diagram of what I intend to do.

    Just a few questions.

    1. As I have read through the thread I have surmised that the distance between your dc/dc charger and aux batteries should be as short as possible. Well with one of the batteries located in the back of the caravan and one in the back of the bakkie this is not possible.
    Will 10mm2 cable between dc/dc charger and back of bakkie be thick enough?
    The caravan already has 16mm2 cable from front to back where battery is and has its own solar regulator ect.
    Is this tottaly impossible to do?

    2. On the dc/dc charger there is a port for a signal wire from ignition of bakkie which seems to be a "preferred" option. Alternatively one can short it via the positive port of main battery. What is the difference is the preferred option really necessary?

    3. Is it better to run all the appliances (fridge, lights, compressor ect.) from the load port of the dc/dc charger or straight of the aux battery? Should one split them? thus run some through regulator and some not?

    Thanks

    You can probably make it work, but I think you should have bought 2 x 12A HCDP controllers. Let's hear what the gurus say?

    Someone who knows own more than me may give more accurate advice, but I think you'll be fine.
    I do suggest that you run your fridges et al from the load port on the charger.
    It basically splits the work the charger does between the batteries and the appliances. In doing good so it can push the full 30amps into the batteries while only supplying amps as needed for the fridge and the rest of the load.
    I reckon your cable thicknesses are fine. And the 16mm valuables to the caravan is sufficient. Your charger will be in the back, so the distance between it and the caravan battery is not that long.
    That 30a charger is a monster.

    I agree with PhlippieV.
    Those 16mm˛ cables to the back should do a fine job of keeping battery #3 in shape.

    Thanks for all the feed back.

    I am planning to install this weekend.

    Just a final question on the two diagrams I got with the HCDP dc/dc charger (as mentioned) there is two ways of connecting it.

    One with a 1.5mm2 signal wire from the ignition of the bakkie (preferred) and another where you short this out by "steeling" the signal from where the positive of the main battery connects. (like a short jump wire)(alternate option)

    But on the diagrams the wire thickness of the preferred option is 10mm2 from the main bat to the dc/dc charger and for the alternate option the that wire thickness is 16mm2.
    Why is that ? Is it a mistake on the diagrams?

    I was thinking of not meddling with the bakkies own wiring so was going to take alternate option but if this means 16mm2 cables then I will probably have to get a signal wire from the ignition?

    thanks

    It is no mistake.

    The thin wire from the ignition switch is merely a signal carrier cable (very low current). The 16mm˛ line from the battery has to carry the full charging current, and it is therefore subject to significant cable losses if it not thick enough. A too thin cable here will affect the performance of the HCdP by interfering with the switch-on and switch-off points.

    Yes but why with the signal wire only 10 mm2 wire is needed and without the signal wire it needs to be 16mm2?

    Probably an error in the documentation. Also check if you have the 12A and not the 30A unit's documentation. Contact Manie at HCDP if still unsure?

    Have checked it is 30amps docs.

    It is not an error of the documentation.

    With the signal wire, the relatively small voltage losses across the 10mm˛ cable can be ignored. When you use only 1 cable to carry the high current and sense the voltage levels, the 16mm˛ is required. It helps to not affect the switching points of the HCdP too much due to the high charge current.

    The thin sensing cable from the ignition switch avoids this problem altogether - therefore it is the "preferred" solution. The 16mm˛, if fitted, will give you good results.

    The signal wire transfers the "true" battery voltage level to the HCdP.

    This is needed by the HCdP unit to accurately set the points where the unit needs to turn on or off intelligently. It allows the best situation for battery health - both the cranking battery and the utility battery.

    Thanks Eggie.

    I do not want the hassle of 16mm2 wires. So then I will just steal the signal wire from window wiper positive. Will be easiest and use 10mm2 wires.

    Wait: The connection from the ignition switch is also to signal the HCdP unit when the alternator will be active, ie engine switched on. Should you take it from the wiper, this will not provide the correct info to the HCdP.

    Mmmm: Spoke to the guys at Toyota and they said wiper positive would be best bet. As getting to the actual ignition positive is difficult because you have to open up the main trunk of wires. There is a few wires going to wiper motor but one of the positive ones is directly connected to the ignition.
    This is why when ignition is switched off the wipers goes still and when switched on the wipers goes on.
