Projecta 30A 4-Stage Automatic Solar Charge Controller – SC330
The SC330 is designed for solar panels producing up to 30A, commonly used in caravans and remote setups. It features a multi-chemistry charge profile, built-in temperature sensor, and LED indicators for easy monitoring of battery and charge status. Manual load control allows switching the DC load directly from the controller. Low voltage disconnect (LVD) safeguards batteries from over-discharge.
Features:
- 4-Stage Automatic Charging: Bulk, absorption, equalisation, and float stages for optimal battery care
- Multi-Chemistry Support: Wet, AGM, Gel, or custom user settings
- LED Status Indicators: Quick reference to charge and battery conditions
- Manual Load Control: Switch DC load on/off directly from the controller
- Temperature Sensor: Optimises charge performance and provides added protection (optional sensor probe available)
- Low Voltage Disconnect (LVD): Protects batteries from over-discharge with adjustable settings
