Portable solar storage
(Preview)
I have a 160 w folding solar panel and was wondering where and how is the best storage position. It is approx 750 mm x 750 mm and about 15 kg, not something you want flying around the van while you are driving. Is it best to store upright or flat? On the bed or under? or beside with a pillow or similar wedged upr...

Gross solar feed-in for residential solar installation
(Preview)
Our house has a 1.5kW solar system wired up as a gross feed-in installation. That is, we have 3 meters -- one meter for peak power, a second for off-peak, and a third for solar. The solar output connects to the grid side of the peak and off-peak meters, meaning that we have a gross metering system. However...

Solarking SD2430S Anyone using one of these?
(Preview)
I have a Coromal caravan at the workshop with one of these Solarking SD2430S controllers fitted. Looking on the web it suggests they are an MPPT controller, but I can't find the exact part number to get the specs, just Solarking products with similar part numbers. I have found a reference relating to t...

Some of you may remember sometime back that I did a considerable amount of work re-doing our solar system. Replacing the two hose batteries from Gel to AGM, and then, having three 150w panels on the roof began a re hash. I replaced two solar controllers with one big one, ran new wiring to the controller t...

Two controllers (again)

I read the post just below a number of times but it ended up way above my ability to comprehend. I often have two controllers working at the same time. A morningstar 30a PWM looking after my roof mounted panels (400w) and a DC DC charger with solar input that I connect a 140 watt portable panel to. I keep rea...

I removed the solar that was fitted up around 7 yrs ago and ran 2 lengths of house rooftop solar panel raling from the front to the ba...

pop top solar panel install (video included)
(Preview)
Hi All, I finally got around to installing my solar panels on the caravan. I'd always had an idea of how I wanted to do it and got my chance to try it out. Since I have the pop top the center of the roof is a very light tin and is not capable of supporting the weight of the panels outright. Luckily the outside of t...

Just wondering if anyone has used these in their van? We do have a basic controller coming with our van (standard base offering) which I thought of upgrading. I've read about PWM and MPPT (and don't want to start any arguments) but the existing unit I believe does not have a specific calcium battery set...

Solar regulator position.
(

)
(Preview)
Its my understanding that the regulator for solar panels to battery is placed as close to the battery as possible to avoid voltage drop, thus allowing the batteries to reach full charge. The problem I have is, I have noticed that all portable panels on sale have the charger fastened to the back of the pa...

It was a BP solar 150W, made in USA, polly panel with the usual cheap PWM regulator stuck on the back and a longish cable with an anderson style plug. Quite a lot of lookers while I was there. A bargain at $50 re...

Not really RV solar but.....

Gday... This is a proposal being considered at the moment. The size of solar panel or wiring is not the question, just where would one suggest the positioning of solar regulator/s? Cheers - John

Coaster. start batteries 24v. House batteries 12v. While sitting at home I have it connected to power.

Hi all .( Gurus') I was reading on another site of a fellow who had 2_lots of 250 watts of solar being fed into his battery bank with 2 20 amp controllers. I am wondering as to the efficiency of this setup or whether it would work better with the 500 watts of solar feeding in to a one larger amp controller....
