The DTE-3F1S<\/b> switchboard is used to reduce the mains voltage generated by a photovoltaic installation by connecting additional electrical energy receivers.
\n The distribution board allows you to connect a single-phase receiver to a three-phase network. An additional receiver is connected directly to the phase in which the overvoltage occurred.<\/p>\n
Principle of operation<\/b><\/p>\n
The inverter converts the direct current generated by the photovoltaic panels into alternating current, which we receive in our outlets and the power grid. After leaving the inverter, the energy powers your home’s appliances, which are then sold to the grid. However, if the voltage at the inverter exceeds 253V, the inverter will shut down or reduce the system’s power.
\n When a three-phase network is unbalanced, a significant voltage surge can occur on one of the phases. Each phase is equipped with a voltage relay that analyzes the voltage and connects an additional load (e.g., an electric boiler) to that phase if the set limit is exceeded. This connection is made via a phase switch. This is necessary to protect against a phase-to-phase short circuit when the set voltage limits are exceeded on two or three phases simultaneously. <\/p>\n
