    After much toing and froing, panicking and fretting and absolutely superb advice and guidance from our Techno100 (many thanks Andy) and Vlad the great impaler, all my solar kit has now landed.
    2x100w panels, 20a MPPT controller with remote screen/control, end spoiler mounting brackets, fuse boxes, 6mm cable, ends, screws, Sikaflex, activator, etc etc. I even ended up with a mini 12v solar (briefcase) charger toboot.

    Oh' I can feel myself getting all 'environmental' and 'dreadlocked' here, where's the trees to start hugging, chanting and my patchouli oil......
    :Laughing:

    Now waiting patiently (read finger tapping) for a bit of fine (but not too cold) weather. Fitting the controller and cabling tomorrow. The 2x100w panels are going to be cabled up in series to give 24v and the MPPT will bring this to 12v to charge my 2 x 110ah batteries in parallel.

    I have removed a great roof rack to fit the system - will be up for sale if anyone is after a cracking roof rack,,,, not a cheapy either.:BigGrin:

    I am REALLY, REALLY looking forward to this project. Harri Kryshna!

    I'm thinking of getting rid of my solar & replacing it with a water wheel :RollEyes:

    are you sure about conecting in series as panels give out 18volts i htought they were normal wired in paralel therefore producing 18v s at higher ampage than a single panel and the controlller drops this to the required voltage for the battery

    Sounds like a great kit, very similar to mine. But why series?
    Did the kit by any chance contain a box of sun?

    The point about MPPT controllers is that the input voltage can be much higher, some up to 150Volts.

    The popular Victron BlueSolar Charge controller MPPT 75/15 installation manual is here http://www.victronenergy.com/upload...controller MPPT 70-15 - EN_NL_FR_DE_ES_SE.pdf

    The manual states:
    12V battery and mono- or polycristalline panels
    ● Minimum number of cells in series: 36 (12V panel).
    ● Recommended number of cells for highest controller efficiency: 72
    (2x 12V panel in series or 1x 24V panel).
    ● Maximum: 108 cells (3x 12V panel in series).
    Increasing the voltage instead of the current minimises the cable loss.

    Uummmmm! What Gordon said :Laughing:

    I have been recommended to fit them in series by the suppliers, you could reduce the size of the cable cross section with the 'in series' set-up. However, all guns blazing, I'm going for the 6mm cable AND the in series set-up. As stated above, the MPPT controller will take what the panels can throw at it and give the best output to the leisure batteries.

    Regards,

    Trikeman. :Wink:

    Hi Addie,
    I went for the 20amp Tracer MPPT controller - if you have a look at the 'Trikeman's solar diary' thread I have put a photo of it there, complete with it's remote control screen.

    Hope it helps.

    Regards,

    Trikeman. :Wink:
