When I got my first ebike 4 years ago I bought Grin Technologies DC to DC converter for way cheaper than your gensun controllers less than $100. Also bought AliExpress DC to DC controller mpt 7210a for dirt cheap which also works very well. Bought four 100 watt flexible solar panels that will charge battery from empty to full in about 6 hours. My ebikes have never been plugged into a 110v outlet so I am completely powered by the SUN. I also have a trailer that can pack these panels easily wherever I go . I also have 2 300w panels at home that make charging a no brainer .
Not mentionning, a Solar system must be 48v DC to DC. Charging with a 12v bank system is a waste of energy through bottlenecking precious electrons and overheated electronics BMS can take care of charging control, no need a 200$ charge controllers, this must be payed advertisement
@nicod974 not sure what your talking about that a solar system should be 48v DC to DC. The MPT 7210a DC MPPT controller can charge 15v to 90v at 10 amp max. For 100w panels they charge at 18v and 5 amp and 4 panels in parallel gives 18v at 20 amps which works for a 48v battery. You can also connect 3 panels in series for 54v at 5 amps. For higher voltages like 72v it is probably better to run panels in series as they are closer to the voltage of the battery therefore less stress on the controller when charging to 84v. The MPPT controller is a Constant voltage Constant current and you set what voltage and what amperage you want to charge at and as it gets close to the set voltage it slows the charge down and when it hits the desired voltage it stops so it can't over charge the battery. Silly to think a bms has all those capabilities . If I want to charge batteries to 80% capacity and use say 2 amp for charging this will increase battery longevity and a bms cannot do that. The MPT 7210a can do all of this compared to most controllers and is about $50 US. My 300w panels put out 33.1v at 10 amp each so I run them in series for 66.2 v at 10 amp to charge my 72v batteries . I never use more than 3 amps for charging that extends battery longevity .
I bought a boost converter form aliexprss for $3, boosted my panel from 20v to 42 and put it in parallel with my scooter battery. ITs not mppt but you can adjust the current and voltage with a screw dial , which is basically manual mppt. Thats all an mppt controller is, its a fancey buck boost converter that automatically adjust the voltage and current for maximum power. The only difference is a microcontroller is in charge of the screw dials and changing them to get maximum power. I was hopeing this was a deep dive into all of that but its really a commercial to sell expensive solutions instead of education and informing you. Welcome to youtube, the home shopping network disguised as information.
The best part about those boosting chargers is that you can dial in the voltage. I used the 400w Elejoy unit all summer and put on several hundred miles.
I have learned so much from Kyle in the three years since I bought my Bolton ebike. He provides the best ebike information and advice on UA-cam. Go Area 13.
I run the eljoy step up MPPT charge controller. With it I can hook lower voltage panels up to my 48v and 54v bikes. The controller has adjustable voltage output. Simply look at your AC charger, and match the output volts on the step up charge controller and you are all set!
I have a solar generator for emergencies, but sometimes I do use it to top off my E-Bike batteries. They are excellent for recharging tools like an electric drill. I know QUIETKAT makes a foldable solar panel setup. Like you said those setups are expensive. Man, I would love to hear your take on ferro fluid.
The small high frequency inverters in those battery banks are actually very efficient... generally between 90% and 95%. it's definitely not fair to say that's a place where a "substantial" inefficiency takes place.
It's possible but not efficient unless you are outdoors and have no other option It takes a long time but it's an option.. Could be cool with the right setup
I use a $50 MPPT charge controller, and it's output can be set. So I use the same charge controller for my 36V, 52V, and 63V bikes. I just made 3 different output cables to use depending on the battery to be charged.
I've calculated it costs about 16 cents in electricity to fully charge my e-bike battery plugging the charger into the wall. So, from a financial point of view it makes absolutely no sense to do solar charging whatsoever. Of course solar charging when you don't have access to AC is an option but very expensive because of the cost of equipment.
I don’t want to teach an old dog new tricks however with a little modification, you could use the ‘regen’ side of the controller as you charge controller so long as you disconnect the motor.
You don't want your power station, bike charger, or bike in the sun while charging like that, just the solar panel, because things will over heat..You can charge directly from solar panels if you really know what your doing and are paying attention while charging, but I wouldn't recommend it..I built a bike with solar panels and a trailer, it works good, but I use a cheap charge controller..
I’ve tried this approach with slightly smaller power banks with very poor results. The initial surge of current into the charger goes over the power bank’s limit and the power bank shuts down. (One cheap one fried and won’t output AC anymore.) So I’m hesitant to plug my e-bike chargers into power banks. For my older bikes, I made my own power packs and used a 14v to 48v converter with a current limiter. My newer e-bikes use proprietary power connectors, so perhaps I need to return to the power station approach. For the “why would I do that” people, there are a lot of places where I’m far away from AC outlets and I want to get an extra hour’s riding in.
I have wondered why I haven't seen fenders and racks with built in solar on them. Maybe even a overhead shade canopy that has built in solar on top of it.
All my ebikes, power tools and yard equipment are battery operated. So I charge them all from power stations that I have been charging from solar panels I have setup in my backyard. I haven't a wall socket to charge any battery in 6 years. 😅
I just got a second battery and got a rockbros handle bar bag No need for solar as i don't go camping but i do go to the beach which is hours away... But hey we're all different
dont forget the inverter uses some power! im using a 48V gowatt all in one and days with no sun the all in 1 uses alot of energy after a few days my 100Ah battey is depleteted! i couldnt find the link for Dc to dc controllers genusun?
Using the AC power brick is too inefficient. It'd be more efficient using a adjustable to DC step up/ down converter to 54volts DC along with the panel or powerstations DC output. You can adjust the amps and volts so the bikes battery bms doesn't go into fault mode. Solar panel series connection can help reach the right voltage if they're both 20-30 volts open circuit. I direct solar charge power tool lithium batteries regularly.
Will the small gas generators charge an e-bike? Specifically this one on Amazon Portable Generator, 900 Watts Gas Powered Generator for Backup Home Use & Outdoors Camping Low Noise Ultra Lightweight EPA Ill and CARB Compliant (Black & White)
gensun controllers are much better than cheaper controllers in mobile applications. they recover from partial shade situations, which are common in a mobile applications, far faster than the cheaper ones.
I take my 110 volt tool inverter and use my power tool batteries to run my battery charger, it helps me ride faster plus I ride home at night plus I can charge other stuff too!
Funny how there's no information on here about how much it costs to plug in the free charger that comes with you e-bike and fully charge your battery. Under 10 cents. How much sense is that?

...fun for Louis , channel did a run on a e- bike charging solar as he went from France to Italy . Worth watching, very informative...

Thank you so much! I've been thinking about this subject for some time. I go camping ,this will help loads!😀👍👏👏

Great informative video for solar ! Mike's E Bikes maintenance an repair needs to brush up on auto maintenance and repair lol

Hey thats a cool trick, theres lots of new dogs here so thanks for sharing.

Never thought about solar charging…Interesting
I do this while road tripping. But I keep a low amp charger 2 or 4 amp in the vehicle. 8amp charger drains faster than battery bank.
I have wondered why I haven't seen fenders and racks with built in solar on them. Maybe even a overhead shade canopy that has built in solar on top of it.

i have 3000 miles on my sur ron 100% solar powered miles
dont forget the inverter uses some power! im using a 48V gowatt all in one and days with no sun the all in 1 uses alot of energy after a few days my 100Ah battey is depleteted!
i couldnt find the link for Dc to dc controllers genusun?

@@bigyaoop gensun is an MPPT controller and any MPPT controller does the same thing

Pretty much lost me at solar charging my e-bike….😳😵💫
Funny how there's no information on here about how much it costs to plug in the free charger that comes with you e-bike and fully charge your battery. Under 10 cents. How much sense is that?
more affordable ? the bank alone is 400$
2% of people may need a solar charger 4 times a year? Perhaps that is a good guess
😂😂😂 you are so late to solar charging
