Would like to upgrade the solar panels, plus batteries and I think I will need to upgrade the regulator. Am trying to find a person to advise and fit in Perth Metro area - any suggestions?

Presently have 2 x 130w panels with a Prostar 30 regulator and 2 x 79ah batteries. Would like to change to 3 x 100 or 120AH batteries and add a 40/50amp regulator, then add  either 2 x 150W and keep 1 x 130w panel = 430w, and use remaining 130w panel on roof of canopy of the 4wd.

Or add 1 x 200w to existing 2 x 130W panels  = 460W to van and then get another solar panel for the car.

Trying to get someone out to check it out and advise us, and quote to fit has been impossible - any recommendations??

Cheers

I take it you are not keen to have a go yourself?

I suggest you pay a visit to an electrical supplier 12v, such as Alanco in Welshpool, and ask them for some names of installers. P.S. you may also like to look through the shop as well.
