20A Digital PWM Solar Controller with LCD and USB Output Port

This 20A PWM solar charge controller manages a lead-acid battery bank charged from a solar panel array, using pulse-width-modulation charging for efficient, battery-friendly power transfer. It auto-senses 12V or 24V systems, so there's no manual voltage switch to get wrong during setup.

The onboard LCD reports charging status, battery voltage, and system health at a glance, and a built-in USB port lets you top up a phone or power bank straight off the solar array. Four-stage PWM charge management (bulk, boost, float, equalisation-style behaviour) helps extend battery life, while dual MOSFET reverse-current protection stops the panel draining the battery after dark. Built-in short-circuit, overload, and reverse-polarity protection add a safety margin for rooftop and off-grid installs.

Useful for Indian hobbyists and installers running small solar setups for garden lights, cabins, IoT sensor stations, or backup battery banks.
