    Just wondering if you could recommend a decent MPPT solar regulator from either Ebay or Amazon please?

    I previously had a MorningStar MPPT which was excellent. I also had a Victron MPPT previously. However when I was building my current setup the budget didn't allow for such nice toys.

    I bought a cheap Chinese one six years ago and although it does vaguely provide MPPT it is really crap. The maximum charge voltage is only 13.6V so the batteries never get a full charge when on solar.

    I am looking for a decent solar regulator that will fully charge the batteries and does MPPT properly. However budget is still restrained somewhat so don't want to go for a £100+ one if I can avoid it.

    This van goes next year one way or another so I don't want to spend sunk money if I can help it. The regulator needs to handle 3 x 80 Watt panels.

    I brought the one Andy recomends, very impressed with the output in low light levels.
    Just cross your fingers & hope you don't get caught for import duty & VAT, mine came through OK.

    The link I posted is for dispatch from Germany.
    They also list from Taiwan

    @Techno Will one of these MPPT Solar charge controllers charge more than one battery bank? I have in mind getting two or three 100 watt solar panels and using one to supplement the solar charging of the existing hab battery bank and the other two to solar charge my new battery bank. In other words does the controller have separate outputs that would feed separate battery banks or should I buy separate controllers for each battery bank?

    No
    I have a Sterling battery maintainer that transfers up to 3 amps from one to another. Similer to CBE CSB2

    Many thanks. I'll increase the budget then!

    If you have a B2B which I believe you do then the Sterling unit is mainly an insurance when in storage.
    My solars only supply my inverter battery bank before surplus goes to the hab 12 volt bank

    Mine have never taken longer than 7 or 8 working days from Taiwan. On one occasion it was only longer due to Parcelfarce dragging their feet.
    As it is now available from Germany I'm sure it will be even quicker

    Are you saying that you have a way of diverting the power from your solars once the inverter battery bank is full to your other battery bank other than just 3 amps via the Sterling maintainer? I expect something like that is beyond my skill level! I was also keeping the AutoTrail setup completely separate from my additional B2B, Battery bank and inverter so that I can rip my second bank setup out when I sell the van ready to use in the next one. That's also why I have not yet committed to more solar as its a biggish investment to make if I then sell the van. I expect we'll have a holiday to see how what I've done so far works before spending any more. The original AT Sargent setup with single solar panel and 2 125amp hour Hankook sealed wet acid batteries is still a bit iffy in terms of lasting and I suspect that they don't get enough charge to compensate for what we take out of them hence my thought to add another panel and in due course to perhaps add 2 panels to my new setup to give us a charging mechanism if we stay in one spot and don't therefore use the B2B other than running the engine at idle.

    I brought from the German listing as I have been caught before with import charges mine still came from Taiwan.
