Sometimes you are such a wanker!
I'm surprised it does anything with only a 20w panel on it.
does it convert western democratic sun light into Chinese communist power .
Thumbs and thanks for your Brit humor.
Thats why there is no load connection
Hello there, did you ever figure out how to automatically keep charging – when the sun goes back up again? In order to do that you need to press and hold (setting button) next go to (AMP section) then press and hold the setting button for 5 seconds then and let go. After that keep pressing (setting button) to get to (OFF setting) then change to (ON) with arrow button – this will allow it to auto start charging when the sun goes back up again.
Hi, the Solar panel input have to be higher voltage than output, otherwise it will not charging the battery. Ok
Question please: I have this device powered by a 20 watt solar panel from which I can get 22 watts in the sunshine. From there I am charging a 48V 17.5Ah li-ion battery. Problem is that I can barely get much amperage flow. During charging it's showing a amp rate of .18, not even 1 amp. Is that because the battery is already near fully charged state? Do I need more power from the panel? Perhaps boost up the amps allowed while programming? I would love to get at least 2 amps, Any ideas?
I wonder why the fan is blowing full speed all time when there is no current going out or only very little. So this seems not to be very efficient or well designed, is it?
Seems like it should ramp-up the boost converter, but is starting from too long a duty cycle in the converter. You can still get power on an overcast day (about 10% of max I believe).
it seems very noisy !
Great video I have the same mppt I'm using 200w panels each at 20v and I can get the current to hold
