Intelligence PWM Solar Charge Controller (up to 3A) - SX01-3A

Pulse Width Modulation (PWM) is the most effective means to achieve constant voltage battery charging by adjusting the duty ratio of the switches ( MOSFET ). In PWM charge controller, the current from the solar panel tapers according to the battery’s condition and recharging needs. When a battery voltage reaches the regulation set point, the PWM algorithm slowly reduces the charging current to avoid heating and gassing of the battery, yet the charging continues to return the maximum amount of energy to the battery in the shortest time.

Protection

• Overcharging protection
• Can be used for all panels
• Over-discharging protection
• Short and Open Circuit protection
• If working current is higher than rated current about 5 seconds, LOAD indicator will flash and protect circuit.
  After 10 seconds, the controller will automatically recover.
• Controller maybe damaged if LOAD is short-circuit
