MPPT for Solar Bike

I don't see how that controller will work with the 3 panels.

It has a maximum amp input of 8 amps. Panels at 5.7 amps means you can not parallel them.

It has a max voltage VOC input of 60V. Panels are 21.7V VOC so you can only run 2 in series.

While it may be rated at 350 watts in 48V configuration it can only handle 200 watts if those are the panels you are going to use.

Their GVB-8-Li-14.2V-WP can handle up to 350W of solar.

I suggest using Genasun's Solar Boost for electric vehicles. https://genasun.com/products-store/m...t-controllers/

Great
very light
I forgot about waterproof. Very important
i will use lithium battery. It is a bicycle with three wheel. I will use electricity mostly on hills to help me (and my knees).

If you are charging a 48V battery bank, I suggest using Genasun's Solar Boost for electric vehicles. Especially if you are only using 3 panels, that's nominal 36V trying to charge a 48V battery. Only a boosting charge controller can do that, most need the same or higher voltage. Not sure if your battery is lithium or lead, but they make a model for each. And they are waterproof. https://genasun.com/products-store/m...t-controllers/

For my solarBike, i will probably use 3 or 4 100 watts panel like those

I will use a least one 48 volts battery (1 kWh maybe)


Now I need a MPPT
The lightest and smallest the better.


What characteristic should I be looking for
to select a MPPT for my project.
Thank you
