Outback C0300W 20-55V DC Solar Pump Controller in IP65 Enclosure

The Outback C0300W DC Solar Pump Controller is a robust, intelligent control unit designed to manage and optimise 20–55V DC solar pump systems. Housed in a weatherproof IP65 enclosure, it provides reliable pump control, system protection, and efficient power utilisation in harsh outdoor and remote Australian environments.

Purpose-built for DC submersible and surface-mounted solar pumps, the C0300W ensures stable pump operation under changing solar conditions while protecting the pump motor from electrical faults, dry run conditions, and abnormal voltage events.

This controller forms the core of Outback solar pump kits and is also available as a standalone replacement or upgrade unit.

The C0300W continuously regulates input voltage and output current to ensure the pump operates within safe limits while maximising usable solar energy. By adapting to fluctuating sunlight levels throughout the day, it allows pumps to start earlier, run longer, and operate more consistently than direct-connect systems.

Integrated protection logic ensures the pump is automatically shut down in fault conditions and restarted safely once conditions return to normal.
