MPPT Solar Panel Controller 5A DC-DC Step Down CC/CV Charging Module Display LED
A part of the review has been auto-translated.
I used a LED with the product, used it to drive a small dc engine, ran a modem and charged batteries. I can set when the LED on it goes from red to green, which is important to me when I charge the batteries. The key on it only turns off the screen, it doesn't cut the current. The current and voltage adjustment can be done quite delicately. It can supply five amps of current, but it's three amps and it's getting pretty hot on it. It's quite useful, as long as it's taken care of. I don't have a solar panel, so I can't comment on the mpt feature, but I think it'll provide enough efficiency there. It's quite handy, i like it.
Works well when you manually adjust the MPPT pot and put it on the sweet spot of the panel. Thanks ...
It's all right, as in the description.
The product is good. But i am in need of the manual or instructions to calibrate the MPPT
Work ok and can I can optimize power on my solar panel with a manual tracking. Voltage and current limitation is accurate and there is 100mA minus error on current.
I wanna ask what is the purpose of lamp regulation? and the turning of the mppt knob? when i turn the mppt knob nothing happen
haven't tried yet
This is a unique controller with several options to program. It is very small and reasonable priced.
good product
I'm still investigating where, what and how to setup the module properly - and I'm not really sure, if this can work as a replacement of an expensive pro mppt controller... (afaik now, the good ones sold here in Europe, costing a 10 times, track the moduls voltage over the day and adjusts the sweet spot itself - and retracks, depending on the seasons differing sun ray angle) I rate 3 stars for now, for the missing information, and want to provide here for other buyers, what I found ali. Please look at the pics, as well as in Q/A here regards
