The item is new and not yet been given the full usage.So far though it is working Ok.More solar panels to be connected this week as the old system is moved here.Am happy with the item and also the reply from the seller regarding a question I had.

Sola panel

After using pwm controllers for ages because of the price of Mppt . I see this and opted to buy it. Wow what a difference. I have a 50w solar panel connected to this and as you can see in the photos it still produces power when cloudy but when the sun is out it draws more than 50 watts from the solar panel . So now I have ordered another one to try it on a 100w solar panel. Im a bit mad so I have two set ups one for the led lights in the shed, also connected to an inverter to charge my cordless batterys and one for the garden to supply garden lights and a 12v water fountain.

When used with 2 panels the controller locks up. The settings are lost when the battery is disconnected. Changing the settings doesn't appear to work, i.e. max charge voltage set to 14v it still drives up to 14.5v. Manual confusing pigeon English. It's reading of the battery and solar voltage is inaccurate. I didn't check current or wattage readings but suspect similar misreadings. Cheap mppt but I'm not trusting this in my motorhome!

Well packed good delivery great price seems very well made to me and functional could not be happier
