MPPT or PWM: which controller for your panel?
MPPT or PWM: what each controller actually recovers from your panel, before you buy one.
☀ Your panel and your battery
On a stand-alone 12/24/48 V setup (separate panel, controller and battery), the type of controller directly changes the power you recover. Pick a panel from our catalogue or enter your own specs.
Usable power with PWM
67 W
Usable power with MPPT
194 W
MPPT gain
+191 %
Recommendation
MPPT strongly recommended
Controller current to plan for : 6.7 A (with PWM) · 20.8 A (with MPPT)
Estimate: a crystalline-silicon panel's optimal voltage (Vmp) is roughly 80% of its open-circuit voltage (Voc), the value used here when a full datasheet isn't available. Assumed conversion efficiency: 97% for an MPPT controller. A PWM controller never runs the panel above the battery's charging voltage, whatever its open-circuit voltage.
