Hi Ya, I have purchased a solar panel to charge a car battery so I can run a 12volt water pump to run water around the plot. I had help from a friend who advised me to use a control box to stop overloading and also install a plug socket as the battery, I used to carry it about, stays where it is. I tried the pump using an extension lead and it works brilliantly. I am please with the system. I am now getting a light for the back of the shed. Has anyone else done or doing similar?
