two solar regulators

You need to bypass one regulator and connect this one to the regulator on the other otherwise one will sense the other and shut themselves down so to speak.

It really depends on the design of the regulators.

If the regulator is designed to handle more than 10 amps, then connect the two solar panels in parallel to the input.

As said above use only one (1) regulator.

What brand or type of regulators are they ??

as one would probably be more efficient than the other.
(surely they are not identical ?? )

Hi da

What make are the bi-folds ?

It may pay to bypass both the regulators with a simple switch fitted to the back of each panel and then use a decent regulator mounted to your vehicle that shows amps / voltage etc.

It's a real worry when a solar supplier can't even understand basic electrical units.

From the Suntech website for the 80 watt kit -
"Almost 5amps per hour back into your battery"

da 76,
so you now say you have a solar system and a battery now in the van, are you going to set-up a totally new and different power system or add to the existing system ??

da76,
Why not simply just ask Derek which regulator he would actually recommend for your Solar system, the 'STECA' or the 'SK-12'

He sells both products, so he's not going to loose a sale :-))

I've never installed an SK-12 so I can't coment, but the Steca (lost count) Just ask anyone using them if they would change to anything else, just about guarantee the answer is - no way!!

Originally Derek did recommend the (~$185) Steca-> ""use a decent regulator mounted to your vehicle that shows amps/voltage etc""
he then recommended the cheaper SK-12 panel mounted reg, however your system information had not changed ?

Remember, for best performance, as Derek has said you MUST mount the Solar Regulator at or near the battery, not at the far end of the extension cable at the Suitcase Solar panels.

With a Steca you get to see what Amps are going into & also out of your battery, so you know where to position the Solar panels, and you always know the State of Charge of your battery system, with the cheaper SK-12 you don't have those options.

PWM is a complex system, just because it says it has it, does not mean it's the same % as other brands.

The Steca Features
*BOOST charge (~15+ amp)
*EQUALIZING charge
*FLOAT charge
*Built-in Amp Hour counter
*Automatic load re-connection
*Manual load/un-load switch
*PWM shunt battery charging
*State of Charge battery regulation
*Temperature compensation
*Adjustable settings by two buttons
