Whisper 500 Controller

Solar Charge Controller

The Luminous Renewable Energy make solar charge controller use PWM (Pulse Width Modulation) technology by which the battery charge current is slowly reduced as the batteries get closer to full charged. This topology allows the batteries to be more uniform charged with less stress on the battery, extending battery life. It also keep battery in fully charged state by continuous adjusting pulse width (called float mode). It includes many important features and also overload/short circuit protection of batteries by MCB (Miniature circuit breaker).
