    • Differences between UPS and EPS design indicators

      UPS is a single closed-loop control system of voltage feedback, so its output voltage sine wave waveform and voltage dynamic adjustment precision is better; While EPS inverter control system is a multi-closed-loop control system composed of voltage and current feedback, and its output power has strong overload capacity and load adaptability. High reliability.

    • Differences between UPS and EPS design indicators
    • Differences between UPS and EPS output

      The power supply object of UPS is computer and network equipment. There is little difference in load properties, so the output power factor of UPS is 0.8 according to the national standard. EPS is mainly used as the Emergency Guarantee of power supply, and the load properties are inductive, capacitive and rectifying loads. On-line UPS ensures uninterrupted output power supply and high quality power supply. Inverter is preferred; While EPS power supply is preferred to ensure emergency use.

    • Differences between UPS and EPS output
    • Functional differences between UPS and EPS

      Both of them have mains electricity bypass and inverter circuit, but EPS only has the function of continuous power supply. Generally, the requirement of inverter switching time is not high, and there can be multiple outputs. Some EPS are also equipped with battery monomer monitoring function.

    • Functional differences between UPS and EPS
    • Different application fields of UPS and EPS

      In our country, EPS is mainly used for fire-fighting loads and some electrical equipment that do not have high requirements on power supply quality but need to ensure continuous power supply, only emphasizing the function of continuous power supply. When EPS is used for fire load, its product technology is certified by the Ministry of Public Security. UPS is generally used in computer, digital information system and other occasions. Load with high power supply quality is required, which mainly emphasizes inverter switching time, output voltage, frequency stability, purity of output waveform, no interference, etc.

    • Different application fields of UPS and EPS

Off-grid photovoltaic system generally consists of solar panel, solar charge and discharge controller, battery pack, off-grid inverter, DC load and AC load, etc.

  • Solar panel
    Solar panel
    Solar panel is the main part of the solar power supply system, and it is also the most valuable component in the solar power supply system. Its function is to convert the solar radiation energy into direct current energy
  • Solar charge and discharge controller
    Solar charge and discharge controller
    The solar charge and discharge controller is also called "photovoltaic controller", whose function is to adjust and control the electric energy generated by the solar panel, to charge the storage battery to the maximum extent, and to protect the storage battery from overcharge and overdischarge. In places with large temperature difference, photovoltaic controller should have the function of temperature compensation.
  • Battery pack
    Battery pack
    The main task of the battery pack is to store energy so as to ensure the load of electricity at night or in rainy days.
  • Off-grid inverter
    Off-grid inverter
    Off-Grid Inverter is the core component of off-grid power generation system, which is responsible for converting direct current into alternating current for AC load. In order to improve the overall performance of the photovoltaic power generation system and ensure the long-term stable operation of the power station, the performance index of the inverter is very important.
