A roof-mounted solar array can provide 10-25% or possibly even more of the energy needed to power an electric vehicle. The Real Solar Cars PCDB2105 Step-up DC-DC charger adds solar charging in the most efficient way possible.

Specifications:
Input: 30-43vdc, MPPT intended for 72 cell solar array, should work with 60 cell panels but may not reach maximum power point at high output voltages.

Main Output: 300vdc-400vdc 1A, maximum continuous power about 300w, CV/CC modes, isolated
Aux Output: 13.8vdc 3A, CV/CC modes

Efficiency: 90-95%

Dimensions: 192×159.8mm (7.559×6.291 inches)
Fits BUD EXN-23366 enclosure (not included)
Should also fit Polycase EX-66 and Hammond 1457T2202BK

Powerful Parallax P2 microcontroller, 8 cores, 720 MIPS total
microUSB programming connector, isolated to protect your computer from ground loops

7x general purpose analog input pins

3x 12v half bridge general purpose outputs
2x 12v high side control outputs
5x 12v high side contactor control outputs with coil suppression, 1a max per pin, 2a max total
3 contactor outputs have 0-5v economizer mode
4 wire PWM fan connector, fan NOT required 😎

Dual CAN bus interfaces
