iv been charging my battery up via solar for a few years iv got a mppt charge controller. but iv got a inline inverter so i can just plug the normal charger into the inverter. Works perfect and free power. I love messing about with solar and the bonus part is i got 8 100w panels free and charge controller came on my boat as a spare . my workshop is powered via solar all garden lights are and all my tools get powered buy solar.
This video helped me so much! I have a camper van with 2x320w panels and i wanted to charge my Super73 battery. I bought a separate Victron 100/20 48V charge controller and put the solar panels on a change over switch. I can now put the solar power to my house batteries at 12v 60A or to charge the bike battery with 5A 56v and more importantly, i can control the charging amps, which is something i couldnt do with the existing charge controller. I was thinking of using my inverter before but thats so inefficient.
Definitely achieving the dream of what everyone who has an electric vehicle thinks about... charging it completely for free... without going through the mains! Good job. Glad you didn't push the amps too high!
I have a small solar system and was wanting to distribute the wattage from the panels to both a MPPT charge controller for my battery bank and to auto switch over to a grid tie inverter when battery is full. Was having a problem knowing how to do this until I watched your video on the subject. I bought the right relay and now have a system that does all this automatically thanks to you! 👍🏻👍🏻
Thanks for this. 7:10.. Max Amps setting! wonder how rare to find that feature in charge controllers. How brilliant would it be if these ebikes had a built in DC charge controller that could handle 300watts and a USB out port.
6:17 or you can supply a controller with current directly as long as you’re not getting too close to the max amp rating as it will be rather taxing on the unit. Depending on efficiencies, you could potentially turn a larger voltage pack (100v in this case) with only a few parallel cells (in comparison) to give the power needed.
I watched this video while my eGolf charges off my off grid solar system on my garage. I use a 600ah battery which charges off 6 solar panels and a very large low frequency inverter that can give a constant output of 6kw. It’s a great feeling to drive from sunshine.
I use a Vic 100/30 in my garage on 12V batteries and a victon 375 inverter to charge my ebike and can confirm the bluetooth range is amazingly good, through garage wall through house wall into front room 50 metres away. Its an interesting concept using the victron straight to the E-BIKE Battery, however will you not have to isolate the Pv array during battery disconnect to protect the Victron? The 150/70 is overkill for a 4a charge output, however for the Twizzy it's going to be perfect (You may need a few more Hit 330's :) ) Thanks for this video, your Solar Shed videos helped me decide what I needed for my system.
This looks cool, BUT does it remember all the settings when you change the battery or do you have to go through the setup every time??? Might seem like a daft questions but these things are pretty expensive...
Have you ever been tempted to get hold of any electric vehicles from the past? I'd love to try an Sinclair Zike sometime, and been after a C5 for years, but they go for silly money now, and that's if you're lucky enough to find a complete one.
Yeah absolutely, I’m always looking for interesting vehicles. I did see a good C5 the other day. They run on 24V I think. I should have got it😅 if I’m not careful I would end up with way too much stuff though!
@@andykirby If it's fully working for less than £500 absolutely get it without a second thought. But they are super easy to repair, you just need to keep a eye on the plastic as they go a bit "chalky" feeling with age, like old white plastic garden furniture.
That's nice and simple so I would look at doing that but I was also thinking of being able to use my ebike battery as an emergency power bank at home in case of a power cut so I guess I would just need to convert the battery output voltage to usable home voltage levels such as USB or whatever. Fun stuff.
You should look into a system of moving the solar panels so that you can aim them at the sun then being able to lock them flat afterwards..... That would be really convenient.
Just what I was looking for. Hey, could you use this system while riding? As in, if you had a bike trailer, could you ride and charge from your solar trailer?
What panel are you using? Does it output voltage matter, or if their output voltage is lower, can one just string a bunch in series till you reach over the minimum charge voltage for the battery?
Cool video and good information. I was wondering if I could put use to my folding 50watt solar panel that is just sitting in my storage. The panel specs is something like 18-24 volts I don't remember exactly. My electric kick scooter has a 48 volt battery. And riding my scooter, I like to stop by the lake a couple times a week and cook something using my micro propane stove. Some times I have to charge my scooter at work, or the plug-in at lake (if no one is using the park BBQ grill), or at my storage (very boring).
Did you buy that victron Andy or was it a freebie.must have cost a bomb? Cheaper to use inverter in campervan when sun out and driving with my dc to dc charger .ebay 105£ for charger.had it 4 years on different cars.been on my vw t4 2.5tdi 2 years now.helps charge leisure batteries with waeco fridge that is left on all time .i have one 100 watt panel on van roof plus 3 x 30 watt panels in parallel Also .i use a separate mppt controller for front and back of van .
Hi mate. Do you know how you might be able to charge the 48/52V lithium battery from a 12V deep cycle leisure battery. I'm often wanting to charge my bike battery overnight when the sun isn't out and don't really want to have to use and inverter.
The specs for that controller say 12/24/36/48 Volt. Does that mean you can't use it to charge batteries whose nominal voltage is higher than that, like 72V?
I don’t understand any of that electric stuff but would love to be able to charge my ebike with some form of solar charger while tent camping. I have no idea where to start.
Good video. Interesting concept. I have idea’s of a garage type shed for the Twizy that you drive into. Plug up the Twizy and charge from overhead solar panels (that make the roof). Hmm. Even have a battery bank that the solar shed charges so even on a cloudy day, the Twizy can charge. Hmm. On another note, my work went into lock down today. I am now working from home. How does this lock down effect you and your other half’s work ?
Yeah I’ve seen someone in Germany do this, I think they actually used the same charge controller, very cool. I kind of already do it in an indirect way with my few panels on the house and grid ties. Im going to do some more videos this week and Sarah is doing daily vlogs on her channel during this crazy period so go check them out if you want to see what we are up to! We both work for ourselves so we are mostly at home anyway. Everything is shipping as normal from my online store so hopefully it’ll stay that way. Stay safe mate.
Great job been looking forward to a solar project and this one's really nice charging the e-bike and like you said setup a Twizzy battery charge station from solar what's not to like so many possibilities from solar with the price of electricity going up all the time it's the future. Thanks for sharing your knowledge stay safe and see you in the next.
SUNYIMA 24V 48V 72V 300W MPPT Boost Solar Charge Controller. It also has " user " settings, I use it for a 36v ebike set up, as long as your panels are a lower voltage than the output, it works fine, no bluetooth but its a nice small unit and cheap, if your building a bike trailer mounted unit using 12-18 v panels, I have 7 panels of various sizes mounted on the trailer. 2.5w to 40w.

PS DO NOT load your trailer with 300 .lbs and expect to stop with only bike brakes.... been there done that, almost a hood ornament for a city bus....learn from my mistakes or the hospital bill is on you :) hence the reason for spending $500 to put motors in trailer.... regen braking and disc brake mount for " surge " type braking system to be added later... when my wife gives me the rest of my allowance...
30,000 Euro fine in France for E-bikes going over 28 mph or motor tested over 250w. If you can't pay the fine you can go to jail for one year. No speed limit on regular push bikes. Worth remembering if anyone brings a bike on holiday.
@andy kirby Oi! had this strange idea of doing solar charging m'self. Thinking of using portable folding panels to do 'on the go' charging! Would a 250w Folding panel suffice?. ( the ones you fold up and put in your backpack ) or even a smaller P.V on the bike to charge on the go?. Great video and musik! Greetz from Australia. Mick
Using a solar panel for charging ebikes is great if you aren't on the bike all the time. You carry a big rigid panel and whatever other gear necessary to recharge in your truck or trailer easily enough. But I wanted to be able to do extended duration un-supported bike touring so I finally settled on a 300W folding panel. It's hard enough to move a few hundred pounds around by bike without the wind shoving and pulling a rigid panel attached to a bike and/or trailer all over the place. The panel, MPPT controller, cables, and a dc/dc adjustable converter weigh under 20 lbs. and will charge every piece of electronics I carry which is more than I like to admit. - photos.app.goo.gl/rFim5rPsajmDt8NJ6
@@andykirby Here's mine, which I think you've seen before... twitter.com/ahaveland/status/1057715731297648640 4 x 120 W foamboard panels, sunpower cells, about 1kg each. Using Turnigy Reaktor lipo charger with DC input low limit set to roughly MPP voltage. Current battery 12S 5P 5200mAh multistar lipos, still going after over 4 years use! Currently making yet another panel, and a portable automatic 2D solar tracker to mount them all on.
I was wondering how much current was the maximum suitable. I have a 7s 13p Hailong battery (17.5 Ah) and I have a 2 amp charger and ordered a 4 amp. I was wondering about the 7 amp on the cycle satiator but the charger was too expensive for me to justify getting it anyway for only a single battery. I was thinking about paralleling it with my 2 amp charger for 6 amp using a dual female to single male XLR cable (checking the wiring to make sure it's on the correct pins) but you are saying going over 4 amps may cook the battery? What about a brief partial charge? I mean they can take 25 amps out so why only 4 in?
I d like to do this on my 500W 36 V Powerpack from Bosch but I can t figure out the wiring to connect the three poles the Akku needs to be fed properly
Every try carrying a jackery 240 with you and plugged into the bikes charger, cheaper than buying another battery and lighter in weight. USED while ridding?
Another great video, I finished my scooter build, I struggling to find someone to stamp and sign for the vin plate, based in london what did you do here?
I went to an MOT garage, try and find an oldskool one they should have a stamp set. I reckon You’ll need to take a document with you just to prove your not doing something dodgy.
@@andykirby Legend, garages are just saying no, also here the project i few thing to go but fingers crossed www.reddit.com/r/dualtron/comments/fjklfu/uk_dualtron_thunder_moped/
Maybe try some garages outside London. Scooter looks great, I think the headlight might need to be motorcycle type and e-marked for MSVA... it’ll be interesting if you can get it through though keep me posted!
@@andykirby thanks its e marked and motorbike brightness supernova m99 pro it's the only legal headlight for s pedalics, dip able and has a tell tell light for low and high beam pricey but worth it.
I’m yet to find out... I never actually leave the panel connected without a battery but I’m also aware that when the battery is fully charged no current is flowing so I would presume it’s safe... not sure about that though.
Victron is making a killing with this 800 Euro charger. How long will it take to break even with the cost of the panel & charge unit compared to buying the electricity from the grid?
So your using a 12v solar panel to charge 52v battery. I have the victron as well I'm going to try that. I thought you would have needed to wire 4 12v panels together to get the same result. Cheers.
No actually it’s a 60-70 ocv (open circuit voltage) panel 😁 you can’t do it with a 12V panel unless you had some kind of crazy DC-DC boost converter. The panel voltage needs to be close to the battery voltage for it to work.
Best thing to do is measure your panel voltage when it’s not connected to anything and see what the voltage is. You could series multiple panels up... but you’d still probably need a charge controller to regulate the current unless it’s very low power.
Most Ebike battery BMS are damaged, along with the cells if you charge with more than 4 amps current. (you can charge an ebike battery with upto 8A. but doing that all the time is bad for your battery) That is why you always want a controller.
Aren't you at all concerned the charge structure is that of lead acid. Constant current and Float are old lead acid charge strategies that can be dangerous with lithium.
Float doesn’t have an effect with the lithium profile. CC-CV is how you charge a lithium battery. At the end of the CV phase no current is flowing so if you set your absorption voltage to safe limits for the pack (not above 4.2V per cell) then it won’t be a problem. If you did make a mistake most batteries have a BMS good enough to remove the entire battery from the circuit if the voltage went too high.
@@andykirby Stage One Voltage rises at specified current rating (usually .5-1C). Stage Two, as voltage peaks current decreases. Lastly, CHARGE TERMINATES. Full charge is reached when the current decreases to between 3 and 5 percent of the Ah rating.
Question? How much does it cost to charge the bike with regular power? How much was the panel, charge controller, etc? How long would it take to recoup your cost? Also instead of charging the bike directly during the day (which you would probably be using the bike) The bike needs to be charged at night. So you would need to add batteries to your setup. Charge those batteries during the day while you use your bike and at night plug your bike into those batteries to charge the bike at night. So I really, I don't think this is worth it unless the world shut down and you can not get power off the grid. In which case you have bigger problems then charging your bike at that point! Just a realistic assessment here.
Valid assessment, this is really meant to show an off grid proof of concept. Of course the outlay outweighs the electricity cost. The camping trailer with the panel on the top is also an off grid concept and can run for days with one solar panel and it’s 3KWh battery.
Thats a bit of alot of panels to charge your lil 48 volt ....I guess you couldn't pull that behind on your bike/trailor? you would just use for a base station/chargining station....I would like to see enough power to charge your bike as you go free unlimited power without havining to pull a traier with so many solar panels ? probably weighs as much as a boat ? not very portable? thats the answer / the ticket
Dude your rambling on I'm learning nothing, can I use this to charge me fiido L2 48v 20ah 350 watt motor, if I use 18 v 100watt folding panel on trailer of ebike will this charge? Could I charge battery with system while ruding?

Exactly, for portability it’s not really viable unless you have a very small battery and a foldout panel that you could stow in a back pack.
Could your wind turbine do it?
@@andykirby Here's mine, which I think you've seen before...
twitter.com/ahaveland/status/1057715731297648640
4 x 120 W foamboard panels, sunpower cells, about 1kg each. Using Turnigy Reaktor lipo charger with DC input low limit set to roughly MPP voltage. Current battery 12S 5P 5200mAh multistar lipos, still going after over 4 years use!
Currently making yet another panel, and a portable automatic 2D solar tracker to mount them all on.
I was wondering how much current was the maximum suitable. I have a 7s 13p Hailong battery (17.5 Ah) and I have a 2 amp charger and ordered a 4 amp. I was wondering about the 7 amp on the cycle satiator but the charger was too expensive for me to justify getting it anyway for only a single battery. I was thinking about paralleling it with my 2 amp charger for 6 amp using a dual female to single male XLR cable (checking the wiring to make sure it's on the correct pins) but you are saying going over 4 amps may cook the battery? What about a brief partial charge? I mean they can take 25 amps out so why only 4 in?
I d like to do this on my 500W 36 V Powerpack from Bosch but I can t figure out the wiring to connect the three poles the Akku needs to be fed properly
I read somewhere one of thier three wires were power ground and sensor, they jusleft out. Connecting that one...
Mine has only 2wires
Every try carrying a jackery 240 with you and plugged into the bikes charger, cheaper than buying another battery and lighter in weight. USED while ridding?
That’s more like it Andy, have you done a Solar Panels for idiots series? Considering going down this road but no idea where to start 😁
Mark that positive wire so you don't have to keep getting out your tester.
Another great video, I finished my scooter build, I struggling to find someone to stamp and sign for the vin plate, based in london what did you do here?
I went to an MOT garage, try and find an oldskool one they should have a stamp set. I reckon You’ll need to take a document with you just to prove your not doing something dodgy.
@@andykirby Legend, garages are just saying no, also here the project i few thing to go but fingers crossed
www.reddit.com/r/dualtron/comments/fjklfu/uk_dualtron_thunder_moped/
Maybe try some garages outside London. Scooter looks great, I think the headlight might need to be motorcycle type and e-marked for MSVA... it’ll be interesting if you can get it through though keep me posted!
@@andykirby thanks its e marked and motorbike brightness supernova m99 pro it's the only legal headlight for s pedalics, dip able and has a tell tell light for low and high beam pricey but worth it.
Freopa ah awesome😁 I didn’t realise it was a supernova, they look great!
Is that a tickner trailer? I’ve come her to do exactly the same to mine haha, great video, cheers
What type of panasonic solar panel is that? I can't make out what you said there.
HIT 330 if I remember rightly!
Hooray finally more solar video
Yep it’s been a bit hard up until now as there’s been no sun!
Will it do/auto detect 36v batteries
Isn't there an issue with having solar connected with no battery. I heard it can damage the charge controller
I’m yet to find out... I never actually leave the panel connected without a battery but I’m also aware that when the battery is fully charged no current is flowing so I would presume it’s safe... not sure about that though.
That's the case with cheap PWM controllers. The Victron's MPPT controllers can just disconnect the solar when it's not charging anything.
Victron is making a killing with this 800 Euro charger. How long will it take to break even with the cost of the panel & charge unit compared to buying the electricity from the grid?
The idea behind this charger is that it’s used off grid to charge batteries.
What is the part number for this controller and were to buy one the same? Links anyone please
Do you have a Link to buy All you need?
So your using a 12v solar panel to charge 52v battery. I have the victron as well I'm going to try that. I thought you would have needed to wire 4 12v panels together to get the same result. Cheers.
No actually it’s a 60-70 ocv (open circuit voltage) panel 😁 you can’t do it with a 12V panel unless you had some kind of crazy DC-DC boost converter. The panel voltage needs to be close to the battery voltage for it to work.
@@andykirby oh I see. That kicks that idea out of the park then. Lol
Best thing to do is measure your panel voltage when it’s not connected to anything and see what the voltage is. You could series multiple panels up... but you’d still probably need a charge controller to regulate the current unless it’s very low power.
i wonder how much power a motorized arm to move the panel into the sun would use
this real cool i got battery also 48v and charger says 54.6v 2.0A the settings bit confused about
He's got a 14s battery, you've got a 13s. Slight difference in max voltage.
Fantastic....just need to cover the whole house..what about charging the irobot vacuum cleaner..lol❤😜👍
Most Ebike battery BMS are damaged, along with the cells if you charge with more than 4 amps current. (you can charge an ebike battery with upto 8A. but doing that all the time is bad for your battery) That is why you always want a controller.
It depends on the BMS and Cells 😁
This is so relevant right now! Thanks you’re a ledge
what is VOC and VMP of solar panel please
Interesting.
I'm surprised that you didn't use this to charge some kind of " Tesla power bank " and then charge the bike from the TPB
There probably using BT5.0 or the next one. Every time they build one they should put the newest BT in items.
Yes I reckon so, I’ll ask them.
Wow what a great idea.
Lovely weather it lashing here in Ireland
Aren't you at all concerned the charge structure is that of lead acid. Constant current and Float are old lead acid charge strategies that can be dangerous with lithium.
Float doesn’t have an effect with the lithium profile. CC-CV is how you charge a lithium battery. At the end of the CV phase no current is flowing so if you set your absorption voltage to safe limits for the pack (not above 4.2V per cell) then it won’t be a problem. If you did make a mistake most batteries have a BMS good enough to remove the entire battery from the circuit if the voltage went too high.
@@andykirby Stage One Voltage rises at specified current rating (usually .5-1C).
Stage Two, as voltage peaks current decreases. Lastly, CHARGE TERMINATES.
Full charge is reached when the current decreases to between 3 and 5 percent of the Ah rating.
blob of blu tack™ is a great trick
Mark Ifi yeah i been doing for 30 years and when i saw andy do it i thought oh no .... now the secrets out !
Really need to ANGLE the panel directly at the sun and then move it to track the sun.
Love your passion!
Great video but lets face it this guy seems like a qualified electrician - need to have an off the shelf kit we can buy.
Very cool thanks.
Question? How much does it cost to charge the bike with regular power? How much was the panel, charge controller, etc? How long would it take to recoup your cost? Also instead of charging the bike directly during the day (which you would probably be using the bike) The bike needs to be charged at night. So you would need to add batteries to your setup. Charge those batteries during the day while you use your bike and at night plug your bike into those batteries to charge the bike at night. So I really, I don't think this is worth it unless the world shut down and you can not get power off the grid. In which case you have bigger problems then charging your bike at that point! Just a realistic assessment here.
Valid assessment, this is really meant to show an off grid proof of concept. Of course the outlay outweighs the electricity cost. The camping trailer with the panel on the top is also an off grid concept and can run for days with one solar panel and it’s 3KWh battery.
Nice one Dave 😁👍
Dave?
Thats a bit of alot of panels to charge your lil 48 volt ....I guess you couldn't pull that behind on your bike/trailor? you would just use for a base station/chargining station....I would like to see enough power to charge your bike as you go free unlimited power without havining to pull a traier with so many solar panels ? probably weighs as much as a boat ? not very portable? thats the answer / the ticket
Great video but, Absolutely nothing about the most important thing; how long did it take to charge and an average on a good sunny day? Come on!
Dude your rambling on I'm learning nothing, can I use this to charge me fiido L2 48v 20ah 350 watt motor, if I use 18 v 100watt folding panel on trailer of ebike will this charge? Could I charge battery with system while ruding?
I got bored after the first couple of words!
Did you see the price?....ouch!
Yes it’s overkill for an ebike 😁 but for an electric vehicle not so bad.
So in other words, there's no off the shelf way to do it and if you try to figure it out it's a total PITA...
Fake it till you make it
Not really any good if your out & about on your bike is it? Not as if your going to take all that with you lol.
I understand nothing
I ruined ugg.... holy shit.
