LS-20A Smart Auto Work PWM Solar Charge Controller

Application

PolexTech LS PWM solar charge controllers are designed for solar water pumps, solar lights, household appliances, solar cars, etc. It’s simple, efficient, and reliable, pumping water with very low levels of solar power.

Precautions

• The controller will detect the temperature of the environment to adapt to the charging voltage, so the controller should be as close to the battery as possible. (30-100cm is the best distance).
• 18V solar panel is connected with 12V battery, 36V solar panel is connected with 24V battery. The fuse on the battery side is connected to 1.5 times the rated current of the controller.
• In order to make the terminal firm, use colloidal copper wire. Loose power connections and corroded wires can cause resistance connections to melt wire insulation, burn down surrounding materials and even cause a fire.
• The controller is only suitable for all kinds of lead-acid batteries. Do not use other batteries, such as lithium batteries and nickel-hydrogen batteries.
