Received before the stated delivery date. Item is dispatched from China so might need a longer delivery window.
With a 10Amps input, the controller is cool. I left mine at default settings, works ok.
With a 4700 60V capacitor at the solar input, externally, a normal battery charger can be used as a charge source if no solar cells.
Mine was connected in this way without problems.
An Istabreeze one smelled of burning when connected to a battery with no charge source, totally useless !
This one is faultless.
I just need to do a load test now, but I do not expect any problems.
The output terminals have not been used, the controller might have been designed as a controller for off-grid lighting, nothing in the manual about this, but a load would normally be connected to a battery bank, not the controller, unless it has auto-switching for dusk-dawn.
I am very pleased with the item.

I really like the amount of info you can get from the LCD screen, it gives a very clear viewpoint of what you are using as you switch on and off appliances, as well as being able to see how much power is actually being generated by your cells(Always depressingly low compared with the manufacturers estimates), but it took almost 2 months to get here-a fact that wasn't made obvious in the description, so it loses a star for that

I have a solar system for extracting water from my bore-hole. I have gone through three different MPPT solar controllers. The first two packed up within days, the third lasted just over a year (just outside warranty) and I have decided that the notional gain in energy is not with the much higher price and lower reliability. I was impressed that this controller arrived within three days of purchase - it is now installed and working just fine. But be warned, the manual is written in translated Chinese. Here is an example - verbatim from the manual. "Please avoid the damp dusty, there is a place flammable, explosive and corrosive gases use the controller to install." The sense is just about detectable, but you would not want to rely on the manual for help with setting the unit up.
