Solar Charge Controller, Topcloud 10A Solar Panel Controller 12V/24V PWM Auto Parameter Adjustable LCD Display Solar Panel Battery Regulator with Dual USB Port

Absolutely perfect for maintaining a leisure battery or a car battery, but don't try charging both at the same time.Ideal for caravan use.

Really happy fixed to my solar panel easily and working fine would recommend

I'd only expected a unit that would allow me to charge a battery with a bare solar panel; however, there are features I did not expect. 1. to be able to take power from the panel-battery combination while it is running. 2. to limit the power drawn from the battery so that the battery level does not drop below a set voltage. 3. a timer to control the power output, to day hours of daylight for use with for example a solar fountain (with battery backup).

I’m correcting my poor review! The output of the controller shut down, but now I realise that it’s because the battery had been disconnected! So to get the output back on, you have to disconnect the solar panel’s input, reconnect the battery and then reconnect the panels. Works fine then. It has to be in that order.

It does exactly as it supposed to do

Doesn't stop over charging but good if there will be a regular load. Slightly confusing instructions.

Easy to set up and charges a small lead acid battery for solar lights in the garden, even on fairly cloudy days.4.5 ah batt with 25w ecoworthy panel, feeding a 3w 12v string of led lights.

You have to buy separate leads for the controller to the battery. They are around £25.00. Why do you not outline this in the description??
