## Description

Package included: 20 watt 12 V mono solar panel 10 A solar charger controller 6.5 ft extension cable with Battery Clips 6.5 ft extension cable with O-Ring Terminal

Review: Failed - Salt the controller failed after one day.
Review: 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!
