    Hi all

    On my current van I have a solar panel with a dual battery regulator. One output charges the leisure batteries and one charges the vehicle battery - this keeps both topped up and works really well.

    On my new van (getting it on Tuesday) the solar panel regulator only has a single output to the leisure battery so doesn’t keep the van battery topped up.

    Instead of buying a new regulator with a dual output and wiring it to the vehicle battery, am I correct in thinking that installing a Battery Master would do exactly the same thing, plus give me a bonus of keeping the vehicle battery topped up whilst on EHU when there is no sun as we alway keep the van plugged in at home.

    Richard

    I never bother plugging in at home now. My dual battery solar regulator and panels keeps every thing fully topped up nicely, even in winter.
    Hopefully this scheme should be all you need.

    I have a 170w panel on my caravan and also remain plugged in at home.
    For reasons unknown the garage supply, which feeds the hook up, tripped.
    It was a few weeks (mid winter) before I realised it was on solar only and the battery had fully discharged....not enough sun for long enough..
    The only item running constantly on the battery is the tracker unit.

    As my van is just by the front door I do tend to look in on it at least once a week.
    But I am surprised it went flat with 170W of solar. I have 250W but it if its covered in snow for weeks no doubt it might be a problem. Although I leave nothing on, not even the alarm. You would have to be highly motivated to nick from where it is.

    Ah, snow.....I remember that stuff, white and cold but I haven't seen any worth speaking of for the last 3 winters.

    Ok, my battery may have seen better days but it has plenty of reserve to run the motormover when needed for 10 mins at a time.
    the solar just didn't cut the mustard this winter.

    Yes you are right. Not done it myself, but I believe it is easy to install, as long as you have easy access to Vehicle and Hab battery positive feeds.

    It can be any permanently live feeds.

    The split charge relay is usually a good place because you have all the feeds you need all in the same place.
