I am going to be adding a roof to our porch, and would like to put a solar panel on the roof so I can charge my escooter. However I am unsure where exactly to start.

I believe I need the panels and an inverter to switch it from dc to ac.

This is the charger it uses:

    To manage without an inverter, I would consider a adjustable DC/DC converter.

    1. Small step-down converter with current limit:
    Input voltage range: 6-40.00V
Output voltage range: 0V-32.00V
Output current: 0-5.1A
Output power range: 0-160W

    1. Big step-down converter with current limit:
    Input voltage: DC12-80V (can not be used for 72V battery)
Output voltage: 2.5V-50V adjustable (only buck) (maximum output voltage = input voltage * 0.8)
Output current: 20A (MAX) 25A overcurrent
Maximum power: 600W
Conversion efficiency: ≥ 93%

    1. With serious and silent cooling, dual displays (voltage and current), adaptive current limiting that considers temperature, input up to 120 V DC (be careful, this voltage level is deadly):
    Input: DC 25-120V
Output: DC 1.2-75V adjustable
Current: 20A (MAX)
Power: 600W (Reduce current based on heat dissipation when voltage difference is high)

    Note: dial in less than your full battery voltage. Your upmost level of voltage ripple + measurement error must be a bit below the full battery voltage. Of course, you must have a balancer and BMS (to stop everything in an emergency) on your battery.
