Regulation
Charge Controllers
Sits between panels and battery in an off-grid or hybrid system. MPPT harvests roughly 20-30% more from the same array than PWM, and lets you run higher-voltage panels on thinner cable.
What to compare
- MPPT versus PWM — MPPT pays for itself above about 200W of array
- Current rating with headroom over your array's output amps
- Input voltage window must accept panel Voc at your coldest temperature
- Number of independent MPPT trackers
