Proportional mode power supply is a new feature, which allows the system to work connected to the PV array and to other source of AC power ( Diesel Generator or electrical grid ). The standard operation of the Solar Power Control System is based on solar electricity generation and is sensible from the weather conditions and value of the solar radiation. If the AC source is available, the proportional power supply offers substantial advantages:

  • Uninterruptable system operation
  • Better utilization of the solar energy
  • Automatic switch over from the AC source to PV and vice versa if the solar radiation is rather low or the AC source is not working

If the solar radiation and the AC source are available, the system operates stable with its nominal parameters exploring primarily the solar generated electricity as the AC source injects the missing energy for system nominal operation condition
