Hi all
Can some tell me if you can fit a 235w solar panel used on domestic property's on to a caravan. Just need it to charge the battery or two. As I've been given a couple for free.
charge the bats mate, the power on them panels you have will run the caravan electrics lol.
Joking aside, A BIG YES 2 your question.
But get a regulator and connect the panel to that and from that to leasure battery.
we used a 13w folding panel, kept a trickle going for a week, and no EHU used.
We now have a 80w folding panel jest delivered yesterday, not tried it yet.
But most of my friends on rallies use 60w and that runs 12v tv and other items, for a week or even longer.
Hi that's what I'd like to do. The plan was solar panel to a Dc step down or a solar controller that can handle the panel to 12v then connect to the battery, then use a dc to ac inverter with a 3 pin to round to ac adapter for the caravan.
Can this be done.
Your panels kick out 30v each. If you wire them in series, then your charge controller must be capable of 60v input and 12v output. That is not a standard controller. Most charge controllers are designed for 12v or 24v panels, not domestic ones. Speak to sunshine solar on 01508 488188 and hey will advise you on a suitable charge controller. It will probably be around the £200 mark though.
You could then invert to AC, put depending on what you are running, it could empty your batteries faster than the solar can replace! Go for low wattage items such as LED lights, low wattage TV 35-50W is pretty common nowadays. Avoid the microwave or electric heating.
Again sunshine solar do a range of pure sine wave inverters that will run off your batteries, and they'll advise you of the most suitable for what you are trying to do. £400 should get you everything you need with quality items. Avoid the rubbish on eBay, especially the charge controllers. They will all burn out, trust me I've been through a few!
Hi that's great. Ill give them a call. Would you just use one of the panels as they are quite powerful or use the two of them if there is enough room.
Cheers
Dave.
No, don't go for grid tie otherwise as you rightly point out it will need to be connected to the mains in order to work. They don't have to go into the consumer unit, they can just plug into a socket with a three pin plug, but into the consumer unit is the correct G83 way to do things!
You can use an off grid inverter straight off your battery.
I'm a bit confused in what to do now. You have got me thinking about this. What would you go for. I'd like to store power as well using the sockets in the day. I want the caravan as like useing an ehu but using solar. I want 240v at night that's why I thought a dc to ac inverter that fits on the battery then just plug it in to the ehu point.
Cheers Dave
It all comes down to what you want to run on AC. A fridge will take about 120W, a TV anywhere from 35W to 150W, lights around 35W per bulb unless you convert to LED.
Battery storage here is key so that your AC lasts. You need as many Ah as you can get.
Forget anything that consumes high amounts of power such as the microwave or the fan heater.
