The Solar Kerberos 315B is a state-of-the-art photovoltaic water heating controller that allows direct power conversion from solar panels to heat water—without using inverters, batteries, or grid power. With built-in MPPT (Maximum Power Point Tracking), advanced energy management, and safety features, it’s ideal for anyone looking to maximize solar efficiency while cutting energy costs.
Whether you're retrofitting an existing electric geyser or setting up a new off-grid system, the 315B offers a reliable, efficient, and low-maintenance solution.
Direct DC to Thermal Conversion: Connects directly to PV panels without needing inverters or batteries
Built-in MPPT Controller: Extracts maximum energy from your PV array in real-time
Grid-Backup Compatibility: Uses grid energy as a backup only when solar is insufficient
Overheat Protection: Automatically limits power when water temperature reaches a set threshold
Intelligent Energy Sharing: Optional output for secondary devices like heating pumps
Real-Time Monitoring: Displays PV input voltage, power output, water temperature, and energy yield
Homes with electric geysers looking to reduce electricity bills
Off-grid cottages or rural homes relying purely on solar energy
Schools, farms, and hospitals with high hot water demands
Eco-conscious homeowners upgrading to sustainable water heating
