Solar Power

dorian · dorian

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...

Hi I was at the local tender center this weekend and spotted a good looking portable solar panel. 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...

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...

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...

Hi I received another email from the place where I have purchased some Lithium batteries some years ago. They have a stand at the Melbourne Caravan show offering advice and sales. Possibly a chance to seek them out and have a chat. There may be lots of suppliers there so go for it if money is burning a ho...

We had to make trip to WA and were concerned about the heat. We have a rather aged Hino RB145A converted to a basic motorhome, 24v 180Ah of lithium battery now around 5 yrs old. 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...

Coaster. start batteries 24v. House batteries 12v. While sitting at home I have it connected to power. A 24v charger looks after the start batteries and a dc dc charger supplies 12v to the house batteries and keeps them charged. The 24v charger is connected to 240v. I assume the dc dc charger takes what...

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

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.

My portable 80w solar panels have the controller attached to the back, permanently wired to the panels & with about 4 metres of cables to connect to a battery with aligator clips - I want that to remain even though I realise it could be made more efficient as I use them in the campervan & at home f...

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....
