Hi all,
Just need a little advice.
I have dual Oddysey batteries in my Jeep which are controlled by an ARB smart solenoid and two 90amp wet batteries in my camper trailer which I would like to charge while driving to and from camping destinations. My camper trailer has a pl20 solar regulator which i would like to use to charge my wet batteries.
In order to use the pl20 I would have to reduce the amperage to the unit somehow?? Can this be done to provide 5 to 10 amps to the pl20?
Otherwise I am considering buying an inverter to run a 7 amp three stage charger.
Any ideas or thoughts would be greatly appreciated.
Thanks in advance.
Cobes.

Cobes,
I looked into using a PL20 recently for a similar application, but decided against it - only cause i couldn't justify the cost & complexity. I also didn't like the idea of having high current "Live" wires running through the vehicle. Instead i have bought a great (& cheap iePL20 caravan setup with solar
I believe it is neither elegant nor efficient to run an inverter to run a charger to charge the batteries.
There are numerous posts here & also on the overlander forums discussing how to wire in 3rd batteries & also batteries in trailers. use the search options on each site & you will find heaps of info - beware there is a lot of confusion re wire size. Read Colin Rivers excellent books, posts & web site for clear info on 12v electrics.
Also have a look at alternative power sites like
rainbow power company & marine shops such as whitworths. They are also a
mine of good info / products.
FYI, I bought Anderson Plugs cheaply online from FARNELL
Part no's
397-4017 red
397-4029
grey
both of which are $6.98 + GST per connector including terminals.
Order two of either part no to get a pair for about $16

Cobes,
In my haste to send my response I stuffed up some HTML coding of a link which meant that the first bit of my reply doesn't make much sense. Sorry for that.
Have a look at this site for something similar using a PL20
The charger I bought is a 7.2A switchmode charger made by "MeanWell", model PB120p-13c from Computronics in WA. It doesn't do an equalisation charge, but does have a "soft start" for flat batteries as
well as 13.8v float & 14.4 v boost.
Also find out the specs / info on your batteries from the manufacturer or distributor so you can program the PL20 accordingly. The PL20 manual can be found here, while the technical manual, is here.
Cheers
Crozdog
