[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

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!

Great value, does the job :)

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

Perfect item works well

Installed as said wouldn't even let my solar panel charge the battery or let me turn on /off my lighting

I've had a very similar regulator for years and they do the job. This is a bit more sophisticated as you can program the various charging, switching and cutoff voltages. The rear can get quite hot when using the usb ports.Personally I would pay more and get the Bluetooth managed Victron regulators. They don't have usb ports but the management app connects via Bluetooth and provides a wealth of data and configuration control. In fact I did replace this with the Victron 10/75 Bluetooth regulator.

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
