I have a similar set up for charging my recumbent trike. I started out using the same 7210 mppt controller but I found it inefficient when shadows or even a slight cloud went across the panel the controller would shut down for about 10 seconds. I now use a different boost controller that is not affected by shadows and it has no fan so it's silent. I have been using it now for about 12 months and it has worked flawlessly. It costs about the same as the 7210 but it's heaps better. My panel lives on my trike so I never have to plug in to mains power.
Steven Raftis, yes it will charge a 48v battery pack. I will be putting up a video on UA-cam sometime this week with my whole set up and how it is configured. I ride a recumbent trike and use a 200w panel as a shade roof that keeps my trike charged. I have never had to use mains power since.
Very nice work! We are looking forward to charging our battery from Sunlight as well, we just recently purchased a Genasun MPPT Boost Charger to charge our 36Volt nominal battery. This model Genasun charges up to 41.7 volts which is full charge for this lithium battery we are using. It’s really great to be able to charge batteries from sunlight, truly interesting. Great video!
I have just bought one of these to charge my ebike battery- what awg is the cable from the mppt to the battery? Is it 18? And are those xt60 connectors? I am planning to use 2 flexible 100w panels in parallel- I have a 36v battery. I would like to use it on the move- like the Sun Trip riders- not sure this charger will be too good at that- but I can’t afford a genasun!! Thanks for this video- very helpful.
Hello angryguy I’ve ordered a Minghe mppt7210A solar charge controller from a Chinese seller on amazonuk and I’m wanting to charge my 500 watt, 36volt ebike battery with solar power. I'm completely new all this stuff. When I plug into the wall socket, the cable runs through a transformer and lights on the ebike battery light up to show that it is being charged. But when I tested the minghe in bright sunshine, the lights indicating charging did not come on. My question to you nyangeryguy is,to charge my battery with the minghe controller, do I simply have to jam the ends of the solar panel cables coming from the minghe, into the socket of the of the battery, differentiating between the(+) and (-)? It wont be a firm connection, but is that you actually do Regards Rob T
I find the charge controllers go over voltage especially with cloud because they don't react fast enough to solar power levels. Maybe the bms will cope with this but I would have a second buffer battery for safety.

Nice vid and nice setup!
what parts did you use to make the cable that plugs in to the battery ??

What wattage size panel can I use for 60v battery. My charger says 67.2 amps
Will it charge a 36v batter from a 140w 36v panel with max 44v?

What is the rated power for the solar panels?
150w each these are HQST panels. I have seen 240w on the controller in decent sun.
Hi. I am trying to charge my battery. But it doesn't. Can you help me?
you only added just over 1aH to it, no wonder it only took 30 minutes, it was basically full already
