The goal of this project was to install a comprehensive off-grid solar power system that ensures a reliable and robust energy supply for various high-demand applications such as air conditioning and welding. The system integrates both AC and DC coupling to ensure efficient power conversion and prevent system failures. The 19.3 kW solar array and 40 kWh battery bank provide ample power to handle high-demand applications. The setup includes automatic black start capability, ensuring the system can restart independently if the battery bank is depleted.
