With modular design and robust operating capabilities, COOLNET's solar systems can be easily retrofitted onto existing infrastructure,resulting in reduced diesel use, longer service intervals and extended DG operating life. The solution will dramatically lower operating expenses, thereby simultaneously reducing logistic and security costs and concerns. Our hybrid system can be integrated with diesel generators to form a hybrid off-grid system, increasing the flexibility and reliability of the entire micro grid system. lower dependency on fossil fuels will improve the resistance to risks caused by their volatle prices. Solar input voltage DC output voltage 85-440VDC (Normal: 220VDC) 42-58VDC Typical load Acoustic Noise < 5KW ≤ 55dB
