PV inverter SIRIO K800 HV-MT

centralthree-phasetransformerless

MAIN FEATURES • Suitable for use in medium-high power plants connected to a medium voltage distribution network • Max Voltage 1000 Vdc with open circuit to allow the configuration flexibility • High conversion efficiency • Built-in string box having 16 inputs with fuses and monitoring of the individual currents • Full nominal power up to 45 °C • Speed-controlled fans to optimize the efficiency • Colour LCD touch display with datalogger function • Fully accessible from the front • 2 expansion slots to connect communication boards • MCCB AC side and switch DC side • Suitable for operation with modules that require the grounding of a pole In order to increase overall plant efficiency, the Sirio HV-MT Central inverters do not have an integrated transformer. This feature and the meticulous design make them ideal for use in medium- high power plants connected to a medium voltage grid. Maximum energy and safety The Maximum Power Point Tracking (MPPT) research algorithm implemented in the control system of Sirio Central inverters allows full use of the photovoltaic generator in any radiation and temperature conditions, making the plant work constantly at maximum efficiency. In the absence of solar radiation the converter goes on standby and resumes normal operation when there is radiation again. This feature reduces self-consumption to a minimum and maximizes energy efficiency. The use of speed-controlled fans helps to optimize the overall efficiency of the inverter.
