Fitting solar at Techenders

  1. Going to follow the perimeter of France, hopefully doing 50 miles a day for 3 months. Can't carry the laptop etc for blogging unfortunately.

  2. Thanks - already crossed swords with a sodding pothole and still got the sore ribs to show for it! See you at Techenders on the Friday.

  5. Woooo. Loads of power!
    Hopefully also if I’ve not got an appropriate tool or two, you might have them.
    Is it a relatively easy job now Si as you’ve got one there already? Just add a junction to the existing wiring and glue it all in place?
     
  6. Yep, so long as he's got a charge controller that handles 20 amps potential he's good to go.
    ( I mention this @scrooge95 coz if you get a 20 amp one now, you won't have the expense of buying another controller if you do decide to add another panel in the future...)
    A couple of MC4 branch connectors to bring both +'s and both -'s from each panel together, and on into the cables that run to the controller...
    Cables spec'd so there's no volt drop over the run (4mm should be fine)...
    Fuses rated for the cable runs...
    Glue it on and....

    No more hook-up for @1973daisey yay :thumbsup::thumbsup:

    @scrooge95 you are a top swotter! You make the rest of us (me particularly) look lackadaisical:)

  8. Rather topically we've just had a solar related conversation.
    Mrs Monkey and I have decided to stay put in the aire we arrived at yesterday as Montville is a lovely little town.
    Anyway it's a bit overcast but the 100w panel is still pulling about 1.5a.
    Not a lot but we've got the fridge running, a pure sine wave inverter for the lap top, 3 mobile devices charging, a torch on charge, plus the blue tooth speaker and the iPod:eek:
    Terminal voltage is currently 12.9 but that will drop as the solar charge going into the battery wouldn't cope with that draw all day
    It's a 140 amp leisure battery though so I guess we can always top it up when we travel south tomorrow:cheers:

    Look at you with all your travellery petrol cans! Where's Montville? :)
     
  10. Montville is just north of Rouen in Normandy.
    We got off the Newhaven to Dieppe ferry yesterday pm so just wanted a close stop.
    One gas can, 2 black water cans and the red one has got 10l of 20.50 in it for service oil changes lol.
    As you may recall, yes I was a Boy Scout;) x

  11. Ha ha , not sure about that, but thanks!
    I've got to keep motivated towards this as Clem is away being welded at the moment, and so there might not be much time between him returning to my driveway, slinging some bedding in the back, and heading for Victoria Farm!

    Have you been here Mr Bus Monkey? We stopped at a camp site here on our way back from Spain last year. Our pitch was right on the river :). I know you don't really do camp sites but the village is nice :) . It's probably near you right now!! X

  13. So as a bit of an aside, but all vaguely connected.....

    Are all leisure batteries born equal when it comes to the (hopeful) trickle charging of a solar panel?

    My leisure battery died a slow death over the course of last summer and through the winter,
    - possibly a drain on it although I can't think what: there's a zig panel that switches LED lights / pump for the tap / fridge ignition, all of which are off unless being used; plus there's the VSR from the starter battery; and the propex (again, turned off unless in use). So I can't see what would be draining it.
    - possibly buggered it when directly connecting a borrowed freestanding solar panel in the dark at a campsite, and foolishly thought that the panel fuse would be on the positive side. Wrong. Blew the fuse, but maybe wrecked the battery?
    - or maybe it just slowly died of natural causes.

    Either way, it's done for. Not a hope of getting it to hold a charge, so I've (temporarily) resorted to my old original one that came with the van and still seems to be capable of retaining 12.4V. It'll be fine to get the solar hooked up to at Techenders (I think), but as and when I get a newer better one, what should I look for with a view to it being constantly connected to the solar? Is there anything special? Should I disconnect it when not in use in the winter or is it just fine with any old leisure battery to keep it connected 365 days of the year?

  14. Have you got a ctek charger? If you have you could try a recondition cycle on it, it won't make anything any worse. If you haven't I can bring one.
    See you at Eddie's

  15. Ah no I haven’t got a ctek, just a bog standard trickle charger.... to be honest the battery is dead, c’est la vie, most likely my fault.... but if I do buy another I just wondered if any were better or worse for a solar set up, or if they’re all just basically the same and good for the job.

    See you at TE
     
  16. I think I'm just a tight git and can't throw anything away until I've tried to fix far too many times. Humph old git.:)

  17. Ha ha, no I think you are just sensible! I’m the same, but nothing I’ve tried will get it to hold any charge at all. I’m intrigued about a recondition mode on a ctek though. It’s vaguely on my list to acquire one, but a way down it. I think the charger I have is supposedly ‘smart’ (according to the friend who bought it for me) but I always think ‘smart’ is a word very open to interpretation..... and probably coming from the person who opted to connect up a solar panel in the dark, rather than wait until the morning when it might actually do something, I’m really not the best judge of ‘smart’!!!
