Looking for someone who could recommend what I'd need for a solar panel to power my 52V battery and 1500W rear ebikeling motor. I've seen several people online who have done so and want to do the same. I'm going to start my own channel as I travel through the Philippines as soon as they lift this pandemic hold. I want it to charge my e-bike and run a small travel fridge and freezer, plus I want to have a solar powered generator and battery in the trailer as well. Any advise would be great and appreciated!!!

Sounds like an awesome trip idea!

Checkout this guys rig over here for some ideas:


How many Watts or Amp Hours is your 52V ebike battery?

Your best option would be getting a nifty little device called an MPPT solar charge controller.


You then have a couple of options:

1. You could wire a 12V solar panel straight to the input of the MPPT charge controller, and then the output to your 52Volt ebike battery.
2. A better option is to use the extra battery in your trailer (eg. a 12V deep cycle battery) to charge your ebike battery using the same MPPT charge controller. Just wire the 12V battery to the input of the MPPT charge controller, and then the output of the MPPT to your 52Volt ebike battery.

Option 2 means you can can run your fridge and charge your ebike battery from the 12V battery in your trailer. You then run your 12V solar panel to charge the 12V battery in your trailer. The solar panel will also need another normal solar charge controller to charge the 12V battery, but these are much cheaper since they don't need to increase voltage. Here is one here which will do the job:


Your 52V Li-ion battery will need to be charged up to 58.8V. I believe the MPPT controller can be dialed in to whatever voltage and amperage your battery requires to be charged at. Although it doesn't specify a 52V battery on the listing, I believe you can set the output voltage and current according to the actual requirements of your battery.

Hope this helps!

Also because you'll be in the Philippines accommodation is very cheap ($6/night at a hostel or $12/night for your own room) and you'll be eating out at restaurants a lot. So bring along your normal mains ebike battery charger and plug it when you stay somewhere overnight or wherever you see a socket in a restaurant.

Also bring a small 12V battery charger that runs of mains power to charge your deep cycle battery. Here's a nice compact lightweight one here:


If it was me, I would not bother about a fridge or cooler. I had a solar setup on my 4x4 and powering the fridge takes most of the power (although it was a medium sized fridge) and that was with a massive 200W panel and 120Amp hour battery. I would save your precious solar power for charging your ebike battery. Solar power is great, but you have to consider that they only put out their maximum amps when they are in full sunlight and angled directly at the sun.

Have you travelled in Asia before? Cold beer is $0.50 for a pint and hot meals are a $1 for a full plate if you find out where the locals eat! Slightly more expensive if you eat at places which cater to travellers. But just go where the locals eat and point at what you would like and you'll pay local prices!
