I have just finished installing a PPAP Diesel heater and Im having some issues. It seams the ECU is the main cause and the seller is sending a new one. My question is about the operation of the fuel pump. When I primed the system and applied power direct to the fuel pump it clicked once then stopped. By co...

Can someone explain, in layman speak, so that I can understand it, please We are informed that 12VDC cable should be a minimum of six square millimetres area, and that larger square area is better, for less voltage loss A normal 12 volt 30 amp blade fuse has a much lower, (never measured it), square are...

Roughly how long should it take to charge one 100a.h. deep cycle LA battery using a 200 (72cell) panel if starting from a battery at 11.6v. Controller is at the battery & all wires are correct size. What is the resting voltage of a 100ah LA deep cycle battery after the surface charge has dissipate...

Anyone out there got any information on the durability of flexible solar panels ?, these are the ones with a fiberglass or plastic backing, and have 3 eyelets each side to attach. I am not asking about the ones that fold up into a small square, these can't be folded, and perhaps not even rolled up. They ar...

Anyone had one fitted aftermarket? Any recommendations or disappointments? Seems a few on the market, Dometic, plus one just labelled 5.8" caravan and another 7" motorhomes. Heard mixed opinions on wireless ones. Advice appreciated.

We are at older sons place in northern New Mexico at 8000. The temperature dropped to 9 F with 10 of snow. We put a 60 W lamp in front bay with the LFP battery suite and it kept the space above 40 F. Son ran an extension cord to fifth wheel after I whined about needing to probably run generator in morning since I...

Hi everyone. What amp controler would I need for 500 watts of solar? ie 2 x 250watt mono panels. Thanks. i looked on here but couldnt find the answer.

Okay, have got two panels up and running, with the new regulator ticking away just fine. In at Altronics yesterday, and when I asked the sales person what I wanted, he did a few calculations, and advised that the diodes (2x) for the two 160w panels (4 diodes all up) should be put into a metal enclosure, th...

Hello all, I have an electrical problem that has recently appeared. My vans power consists of 2x 110A batteries 2x 80watt solar panels. At night time whilst running power from 12volt for van, all power suddenly drops out and about 5-10 mins later all power is restored. Then 5-10 mins later it all happe...

Quick question, is there a colour code for the Anderson plug (mounted on the RV) that a portable panel will plug into.

OK I have 2x 120 AH house batteries in the caravan being charged - only by 450 watts of panels, flat mounted. When running short of power, and I should say here, we have a few electronic devices including TV and vast, as well as a 12v compressor fridge. I have the ute set up with a DC-DC charger from the motor...

Title of the thread says it all with the possible exception of saying they'll be supplying a lithium setup. I've always considered Solar4RV to be the recommended supplier but i'm seeing numerous options on evilBay for 'around' the $1 per watt (roughly) price tag. I don't want attached controllers i...

ive just bought a motorhome for the first time. Being a complete novice, I was hoping for a little advice about solar/ 240v power/ inverters/batteries.

Hello members, I did a bit of searching earlier this evening after testing today on the subject of solar panels mounted on an angle or flat on the roof.

Hi all, I'm about to install some permanent panels on the roof of the van and have now come up with a mounting plan based on research. The pop up roof offers its own challenges. The panels have an open circuit voltage of around 40v and are rated 235w. Of course I'll be using a suitably rated mtttp contr...
