এই এমপিপিটিতে চার্জিং ইস্যুর প্রবলেম আছে। মাঝে-মাঝে ব্যাটারি ফুল দেখায় , এসমর অটু কাট সিস্টেমের কারণে ব্যাটারি চার্জ হয় না। কিন্তু ব্যাটারি মাপলে দেখা যায় ব্যাটারিতে চার্জ কম। এটা খুবই খারাপ সমস্যা।

The first one I bought did have a fault but the vendor sent me a replacement board, its been working ok, I was so please with it that I bought another one, which looks identical but the setup options are different. have you check the batteries to see if the cells are balanced? thats the issues I seems to have alot of the time, regardless of what batteries you are using you might want to consider fitting a 5 amps active balancer on it

Actually this was a video I was making to show the seller that the controller did not work, I couldnt post the video to his country so he said to post it on youtube and send him the video link, I didnt realise it was public until someone asked a question about it. beside I'm an engineer not a content creator.

When will people ever learn... This cheap chinese devices are this cheap because there is no testing and no q/c. Usually, the engineering is great but the manufacturing sucks balls. Anything and everything between fake components to incorrect assembly. *You buy these cheap devices - you take the q/c and testing upon you.* I learned this the moment I bought my first cheap-ass electronic thing directly from China: before even contemplating connecting power to it - take it apart and check everything: Loose bolts and nuts, soldering, thermal contact between power components and heatsinks, wrong parts, wrong ratings, e v e r y t h i n g. Then comes testing, measuring, finding knock-off or underrated parts. If you can't do these you either pay the premium and enjoy the warranty of a brand name that did all that for you, you learn how to do it or just make another hole in your budget. ;)

So I'm finding out, I bought one 2 months ago, took 6 weeks to get to me (custom problems) then it didnt work, took 2 weeks on alichat, dozens of pictures and a video to get them to send a replacement board, now thats sitting at customs again, good thing I have some buck converters to use in the meantime. Unless you have a deep pocket for V....n equipments you sometimes have to take a chance with these cheap stuffs

@@dantronics1682 You know... I'm not a bank director either so I DIY everything. I do have a bit over 30 years of experience in electronics tho :)) So, because I ain't no CEO, I went low voltage, modest power. All PVs are in parallel, each panel has it's own cc/cv buck and because the panels are ~34v OC and ~28v MPP and my battery is 24v I'm already pretty close to the MPP on my panels anyhow. And the panels are 2nd hand so they can't put out the rated power, at my latitude, either. The buck converters are ~$4 a pop. You could use 10 in parallel for 100A and still not match the price of a ready-to-pop chinese noname regulator. Now imagine the redundancy in such a setup. Sonething pops? That's $4 and you'r system can still charge even with a small reduction. And you can tune each regulator to the voltage you want, matching your battery and maximum charge you want to push your pack to.
