1. According to the local solar energy resources and load power consumption to match the response capacity. 2. Ensure the continuous and stable power supply of all monitoring equipment. 3. The monitoring equipment shall be powered all day, and the maximum daily power supply time is 24 hours. 4. Continuous use of rainy days, up to 5-7 days (can be increased according to customer requirements). 5. It can provide DC12V / DC24V / dc9v output voltage at the same time. 6. The latest solar energy lithium iron phosphate battery is used as the energy storage equipment, the working temperature is between - 40 ºC ~ + 60 ºC, which has the characteristics of high life and high performance. 7. Special lightning protection technology is adopted to ensure stable operation of the system without interference of thunderstorm. 8. Using MPPT controller, the normal reception and transmission of monitoring signal will not be interfered.
