Topsolar 20W 12V Solar Panel kit Battery Charger Maintainer + 10A PWM Solar Charge Controller +Solar Cable for Car RV Marine Boat 12 Volt Battery Off Grid

I bought this solar panel to trickle charge a car battery in the shed. I use the battery for a 12v lighting system and a small inverter as I have no mains power in there. Its May at the moment and we do have a reasonable amount of sun but I have to say the panel is doing an excellent job of keeping the battery topped up. The panel doesn't have much in the way of mounting brackets, there are simply four holes in the inner surround of metal. It was a bit fiddly but with use of some suitable nuts and bolts I fed the bolts through the holes in the surround, through the wall of the wooded shed and put washers and nuts on the inside. I then put a bead of sealant around the panel to stop the rain dripping down the back. Although fairly generous the leads from the panel to the power controller were not long enough for me so I ended up extending them which is straightforward enough just ensure you get the polarity right. Its worth using good quality wire as thick as that supplied (at least) so you don't get too much of a voltage drop. The power controller isn't the best or the most complex but I found the default settings work fine for my purpose, just follow the instructions to connect everything in the correct order. You can alter the charge voltage and cutout voltage if you wish. The screw fittings for wires on the controller are a little unconvincing but seem OK in practice. At the price point I'm pleased with this panel and I now have exactly the setup I wanted in my shed.

Bought this to set up some lighting in my shed. Fairly straightforward to fit it all together although the instructions are tiny and I had to look up most of the terms. Had to replace the batteries on the wife’s mobility scooter so the old ones will be useful just for lights. So far so good, it all seems to be working OK after a couple of weeks, battery staying charged enough for lights. Made a wooden frame to attach the quite sturdy panel to the side of the shed (not much direct sunlight this time of year but will be in a few weeks time) and put the controller inside. The lead was a bit short so extended it using some 13 amp twin and earth electrical cable which seems to work alright. Overall a good buy for the price and useful as my first foray into a solar power project and my led light strips work fine, who knows I may be expanding it soon!

A good little solar panel, that does what it said it would. I have it charging a 12v car battery for electric fencing for my pony, to save me lugging it across the field and home to charge up. So far so good, keeping the battery charged. The instructions for its use are a bit nondescript, I went on to you-tube to work out how the wee wires went in and how the controller works.

Arrived promptly. Easy to set up (if you spend enough time studying the disorganised user manual, in v small print. To be fair everything you need is in the manual, just not in an oder a new user needs). Smeone asked for a copy of the manual, so attached here.

Bought this kit to power a few simple 12 volt led strips to light a small garage without mains power. They panel is quite small but it seems enough to top the battery up with my useage being fairly light. I used an old car battery which slowly looses charge but the solar kit seems to keep it topped up. Quite easy to install and the control panel is a nice small size. I haven't tried the usb outputs but I can't see why they won't work. I use the lighting circuit on the control panel so you use that to switch the lights on and off.

This product is in perfect condition but has stopped working. I would like it replaced as this is an electrical product that carries a UK 1 year guarantee. However I cannot find any links to return this product, therefore I have found myself writing a review to get a conversation going

Fitted to an older yacht. I’ve bought a second one as the performance of the first supplying the starter battery has been superb. The second is for the leisure battery and the plan is to mount them back to back over a cable rail which will reduce efficiency but they have loads of output and aesthetically much better. The solar regulator allows me to check battery status on arrival at boat and the solar panel has kept the battery in tip top condition. USB works perfectly on navionics and phone. All very easy to fit and appears to be weatherproof after several months. Recommend.

Bought a second unit and this seems to be working so far. I tried another because I couldn't see a decent competitor at this price point and most people were pleased with it. I do wish someone would make a unit with two output circuits to charge dual leisure batteries. It is really not a good idea to parallel up dissimilar batteries and try to trickle charge them with a single unit The first one of these that I bought failed after 2 week - not charging. Tried it an another battery at 12.3V - ie about 50% discharged - unit still not charging. suspect it was actually discharging ( slowly ) the leisure battery which I had it connected to. checked all contacts etc etc . Solar volts and battery volts correct on pin ins to controller. Returned it to Amazon. The cable from the panel to the control box is too short and can’t be changed. I would like to see 2m at least of heavier gauge cabling to keep the voltage drop the same. On the output side of the control box, again the cables provided are too short but you can use heavier gauge into the screw terminals.

Très bien, cependant prévoir un stockage (batterie) il est depuis 2 ans dehors (été comme hiver) et pas de PB

Bien funciona bien

Works as described little on flimsy side would recommend and purchase again no complaints as it does what it says and reasonable priced prompt delivery

Es funcional, de regular a buena la calidad.

Ottimo
