Charge Controllers
Regulate solar panel voltage to safely charge your batteries. MPPT for efficiency, PWM for budget.
MPPT vs PWM: What's the Difference?
MPPT Controllers
Maximum Power Point Tracking. Up to 30% more efficient, works better in cold weather and partial shade.
- 30% more efficient
- Better in cold weather
- Works with higher voltage panels
- Best for systems over 200W
PWM Controllers
Pulse Width Modulation. Simpler and cheaper, but less efficient. Good for small systems.
- More affordable
- Simpler technology
- Good for small systems (under 200W)
- Less efficient
