Description
40 WATT CHARGING POWER - Ideal for medium to large 12V batteries capable of accepting up to 3.3A, as found in a cruiser motorcycle, car, bakkie, farm equipment, or deep cycle batteries used in security or gate opener applications.
PANEL WORKS IN ANY WEATHER - poly-crystalline technology designed to work effectively with variable sun power.
PULSE CONVERSION TECHNOLOGY - Accumulates low current from the panel and converts it into efficient charging pulses ranging up to 5A. High sun means more frequent pulses; cloudy skies mean less frequent pulses.
CHARGER BY DAY, MONITOR BY NIGHT - Charge controller switches between charge and monitor mode depending on incoming power, so you always know the condition of your battery.
Specifications: Solar panel rating 40 Watt poly-crystalline, Vmp = 17V, Voc <= 22V. Charge controller output voltage range 4V to 14.4V.
