Nice video! Hmmm, I love that this system has an easily movable control panel (the whole thing could easily be re-cased in a larger box) but not sure about how it is powered by the solar side. I suppose one could wire in an independent rechargeable battery to power the display. So unlike other systems do you not run the risk of frying the controller if you plug the panels in first?
Also the boost conversion vs buck is strange to me. Isn’t boost conversion less efficient than buck conversion (does boost generate more heat)?
Also do most mppt controllers use fans (I only have a few Renogy PWM controllers but am doing research before buying an MPPT)?
So many questions on this one! 😂
is it real mppt or not? does it work well? I can not find a cheaper mppt charger exept this
What do you think of those instructions?
"Display devices are easy to pollution easily broken, the installation process and avoid touching the collision force, use screws to secure the controller firmly, avoid installation in order to avoid irreparable damage to the internal circuitry in severe vibration device."
translation; "don't break the cheap screen". lol.
I have a problem with mine I follow the instructions but it will not stop at the battery charging voltage. But goes well above. Any tips ?
The technical specs are the same as my charger MPPT CTK 300 has. It has less options, only a simple "display", only one button, 3 LEDs … but NO FAN, what means NO NOISE! 🙂 Outdoor usage is better possible than the device in this video. The user can setup the voltage (24, 36, 48, 60, 72 and user-defined), no more options, but for me it is enough. Price between 25 – 35 Euro.

I just got this thing and ran into the same suprise as you lol
Hi Julian you think I can charge my ebike batteries from 36 to 52 volts from my campervan solar panels?will have 100 watt x2 plus 3 x30watt panels on roof soon.I have 2 mppt controllers .a renogy rover 20 amp and 2 epever 10 amp mppt s available.of course I can use my Krieger 1100 watt inverter with ebike chargers also but if plenty of sun can hopefully charge ebike batteries.I do normally connect 2 x 110ah leisure’s batteries in parallel .my 12v compressor fridge is on all time.I do have a dc to dc. Charger also that runs off vw t4 2.5tdi engine .cheers .steve
Is that real MPPT
It lights up when you from the solar pannel not the battery
Is it possible to feed a auxiliary battery via a cigarette lighter socket with this device? Smart alternator 12V –> auxillary 14,8V
I think I may have found it's niche. I charged my 48v 10Ah with a 36v 4.4 Ah hoverboard battery. It was awesome!
I've ordered an ebike and I'm hoping to charge the battery with a solar panel together with a minghe mpt7210A. The ebike battery is rated at 500watt hrs. If watts =volts x amps and I attempt to charge the battery with 2amps, then volts=500 devided by 2=250v. Since the mpt72A is boost converter which has a limit of 72v, am I right in saying it will keep on charging the ebike battery at 72v at constant current, but will simply take a longer period of time for the solar panel to fully charge the ebike battery? If this is a stupid question, please disregard it. Not only but also, can you remember how much customs charges you paid to have the mpt7210A imported from China into the uk?

I would avoid bang good..
Oof..
