It’s a great unit. Used it to charge my 72V eScooter from 48V battery system. It ran at 260W 51V in and out 84V 3amps. I’ve charged it 3 times... now 3 days later output voltage equals input voltage. It’s not the fuse. Something else broke, probably a mosfet, I’ll check... too bad. Otherwise 5 Stars but now I h as be to fix it...
Impressive how well it’s working. I’ve got a 48V solar System (battery) and charged my 72V e-motorbike 84V/3a drawing 260W in input. Didn’t seem to get hot even.
I’ve figured out that 48V battery system exceeds the maximum input voltage. At 47.5V it works well. Not broken. My wrong sorry!
