[Upgraded] 30A Solar Charge Controller, 12V/ 24V Solar Panel Regulator with Adjustable LCD Display Dual USB Port Timer Setting PWM Auto Parameter Solar Panel Controller

Perfect item works well

I brought 4 of these for caravan and shed installations, they are light, small and very well made. they have a metal backplate with a thermal strip on the internals to aid in heat dissapation. dispite the products vague description. i installed these with 265W solar panels with a peak of 30.5v and it has no issue charging and maintaining a 12v leisure battery. the battery charges at around 14v and will then when full will alternate between charging and standby.i have not used the load connections since this is not needed for any of my setups. make sure to follow the advice of connecting the battery before connecting the solar panels as this will set the brain to ensure it does not over charge/provide too much voltage to the battery if connected the wrong way.this has been running now for 2 weeks. i have 2 12v 105Ah batteries wired in parallel to produce 12v 210Ah and this pwm has worked flawlessly for my use. you can use the settings to reduce or increase the float coltage (max voltage used to charge a battery) you can also change the timings of the load circuit, and decide at what voltage the circuit will work on, so if the battery falls below 10v you can have it stop supplying to the load circuit.for the price, this is a fantastic bit of kit that will set you up for a small solar install!

This unit normally charges Lead Acid Batteries, it can charge other types of batteries but Extra circuitry is required to protect the battery.

Great value, does the job :)

I brought this solar charger as it was a similar design to one I had previously used. Unfortunately today I find the display is blank and despite powering the unit down and reapplying power, the unit is dead. not great for a product that is 5 months old.

This product has been working for months on end, works well with our solar lights with a lifepo4 battery, worth the price

Good quality and quick delivery thanks

first display has failednow the usb 5 volt output has failed.absolute rubbish
