Solar Controller FAQ

．What is a solar charge controller?

Solar Charge Controller (or Regulator) is a device which protects the batteries in a solar electric system from being overcharged or being over-discharged. It is need in virtually all solar power systems that utilize batteries.

．What is PWM charging mode?atically converted duty ratio of pulse current to charge the battery, so pulse charging can make battery more secure and fast full of electricity, the battery disconnect period produced by the chemical reaction of oxygen and hydrogen in the time to re-combination and absorbed, so that concentration polarization and ohmic polarization naturally be eliminated, thereby reducing the internal pressure of the battery, so that the battery can absorb more energy.
