MPPT vs PWM — Proven on the Curve

Same panel, same day: the green MPPT curve stays above the dashed PWM curve all day — the gap widens in weak morning and evening light.

Curves are illustrative simulations; actual output varies with sunlight, temperature and battery state. Hover the chart to read power values.

+30%

More energy charged versus old-style PWM controllers — up to 30% over a day.

Weak-light tracking

MPPT keeps tracking the maximum power point at dawn and dusk, when PWM falls close to zero.

Battery care

Charging is protected in cloudy weather too, extending battery service life.

How the MPPT Chip Works

From panel to bulb in one smart chain — with the widest battery compatibility in class.

Solar Panel 11–60V DC input
MPPT Tracking Chip Maximum power point tracking
Li / Lead-Acid Battery Protected charging
Lights · Fan · USB DC 12V & 5V loads
Comparison Our MPPT Old-style PWM
Charging efficiency 93–97% 65–85%
Cloudy / weak light Stable output Output drops sharply
Battery protection Protects & extends battery life Overcharge risk, shorter life
Input voltage / battery fit Wide 11–60V, Li & lead-acid Strict matching, limited

Figures reflect typical controller specifications; measured values depend on panel, temperature and battery conditions.
