- Using a 100W 20V portable solar panel, i setup my charge controller to charge my 48V battery (54V max).

At last ..!.. someone finally does a practical demonstration of something a solar panel actually may be of use some day ..Thanks!
That charge controller is a nice find... Thanks, Steven!
Welcome
@stevenc22 Looking into it further, it seems that the controller is not really MPPT, but I don't see where that really matters much for this application.
Interesting solar charger,thanks!
How long total from that pannel to charge it fully?
i have a 48v battery what should i set the volage to
That was painful to watch but not as painful as I thought it would be
Nice idea,iI just so happen to have the same 100w solat panel, but will that solat voltage converter stop charging the battery when it reaches 100%? Great video man, thank you.
Yes. It is programmed with max voltage of battery and turns off when full.
@@stevenc22 Good to know, thank you so much.
So what are you looking at to charge a 15AH battery with that solar charger? 20 hours or so?
My battery worked out to under 8 hours
Pro tip: If you use whitening stripes on your teeth, just smile at your bike. It will stay charged.
Can e-bike batteries be charged whilst riding do you know?
Yes
@@stevenc22 Bosch, Shimano, Specialized, TQ, Ebike-motion, Fazua, Panasonic, Yamaha or any safe brand ebike producer does not allow charge while riding. You have retrofitted a Chinese made motor that accepts that, it doesn't mean all e-bikes behave like that.
You understand charging the battery has nothing to do with the motor manufacturer and most BMS will take charge while discharging
Dose the solor charger stop when battery hits the set voltage?
Yes
What's about the connector to the battery? Is this a common connector?
Not if it's on my battery
Yes most e bike batteries use a barrel connection for charging
I could never stand being in that loud of a sound for hours. Not a very enjoyable camping trip.... Also I don consider that solar panel portable (in order for it to be considered portable it would ned to be 1/4 that size) and that converter thingie seemed heavy to carry in back pack and uses up a lot of space.
The inverter is incredibly light. The solar panel is kind of big.
@@stevenc22 just strap the panel on a pannier rack,maybe modify it so abit wider and longer
I asked Bard AI if the BMS and overcharge protection on most Ebike 48v batteries is reliable and it said yes. I then asked it if a 50v 430w solar panel could ever put out more than 60v with a load and it said no. I'm wondering about a controller like this one for that config: Genasun GVB-8-Li-54.2V-WP, 8 A (Input)
Yes this controller can boost up to 90v
