<div dir="ltr">You are spot on about the 12v output form your generator not being intended to charge a lead acid battery. Just hook your trickle charger up to your 230v generator output, and you will be all set. Solar cells will work, slowly. to charge a 100amp battery from a 60w solar cell is going to require a long period of very direct sunlight.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Sep 2, 2016 at 7:50 AM, John Macartney <span dir="ltr"><<a href="mailto:john.macartney@ukpips.org.uk" target="_blank">john.macartney@ukpips.org.uk</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi, Listers<br>
<br>
There are lots of you out there with far more electrical know-how than me<br>
and I'd really appreciate your input - even though my question has nothing<br>
whatsoever to do with Triumphs, apart from getting in the name on this post.<br>
<br>
Liz and I often use our trailer home in the UK at locations where there is<br>
no mains electrical supply and so are totally dependent on the 115amp<br>
leisure battery in our caravan. As Liz has a medical condition which<br>
requires daily use of a mains operated nebuliser for prolonged periods, I<br>
recently bought an 800w inverter generator that cranks out 230v and also has<br>
a separate 12v plug and lead with crocodile clips for 'battery charging'.<br>
Nebulising probs are thankfully now a thing of the past but the thing is,<br>
even after running the genny for about 6 hours, my leisure battery was less<br>
than half charged from the 12v outlet, wouldn't take any more and stubbornly<br>
stayed stuck at 12.33 volts. Fully charged, the reading should be around<br>
14.4v. I've since decided the 12v supply isn't really suited to battery<br>
charging and is more for running a 12v TV or other trailer home accessory.<br>
<br>
As we enjoy going to 'more remote' locations than popular ones where 230v<br>
mains supplies are the norm, I'm still faced with a battery charging<br>
problem. It occurs to me that a way round this is to put my little but very<br>
trusty mains battery trickle charger (runs at about 4 amps) on the 230v<br>
outlet and see if this will work? However, I'm just a bit cautious this<br>
route might have some kind of corrupting influence inside either the<br>
generator circuitry or the charger - or both. Anyone BTDT and can advise? I<br>
carefully considered folding solar panels as an alternative re-charge source<br>
but good ones in the UK cost about $600 and that likely payback is longer<br>
than I can financially accommodate.<br>
<br>
All replies (off list) will be greatly welcomed.<br>
<br>
Cheers, Jonmac<br>
