    DC power generated by photovoltaic arrays to AC power that is delivered to the home loads and then fed into the utility grid with any excess power. The SiE2900, SiE3840, SiE4900, and SiE5300 are the members of the family for the North American market. The overview of the grid-tied solar energy system is shown in figure 1.1.1.

    controller starts and goes through a system check mode and then into monitoring mode until the PV Start Voltage is reached. During this time, the SiE Inverter will not generate AC power. Once all conditions necessary for grid connection are satisfied, the SiE Inverter goes into the Grid/MPPT mode and begins feeding the AC power into the grid.

  • Page 60: Operation

    Operation Overview The SiE Inverter will operate automatically. Once the solar insolation is strong enough to generate DC input voltage over the pre-set threshold value, the inverter turns itself on. The inverter feeds power into the grid after input voltage over the PV start voltage and all necessary conditions are checked and fulfilled.
  • Page 61 grid failure, otherwise it takes 20 seconds normally. If any parameter except the DC input voltage is under the threshold value, the inverter goes to Fault mode. : After the monitoring mode, the SiE Inverter confirms that Grid/MPPT all conditions necessary for feeding the power into the utility grid are fulfilled.

  • Page 62: Operation Feature

    It needs service personnel coming to remove the problems and put the system back to operation. Operation Feature Anti-Island: When an “island” condition is detected, the inverter will stop feeding the power to the grid and/or the load. The “island” is defined as a grid tied inverter maintaining operation and feeding power to a load that has been isolated from the utility power source.

  • Page 96: De-Rating Operation

    De-rating Operation The conditions when the SiE Inverter will take into account and then regulate the output and/or restrict the input power to ensure the system is in a safe operation are described in detail below. Temperature The SiE Inverter will monitor the temperature on the heat sink. Once the temperature exceeds 78°C (172.4°F) the system will reduce the output power until the temperature drops under the critical value.
