Description
Proteus PV Station is supplied in a plug & play format, fully assembled, configured and tested at the factory. It includes one or two Proteus PV central inverters, a step-up transformer, medium-voltage switchgear and an auxiliary power system. The two-inverter layout rated up to 9400 kVA is mounted on a standard 40-foot skid.
The output power of the stations ranges from 3800 to 9400 kVA. Versions are available to IEC standards (with one or two inverters) and to UL (with one inverter). In the single-inverter configuration with the Proteus PV 4100–4700, the DC voltage range is from 835–1500 V to 955–1500 V (MPPT up to 1300 V), the maximum DC current is 2 × 2500 A at 40 °C, with up to 24 inputs with monitored fuses. The rated power is 4095–4709 kVA at 40 °C. The voltage on the low-voltage side is 600–690 V and on the medium-voltage side up to 34.5 kV, with a voltage tolerance of ±10 %.
The frequency range is 47.5–52.5 / 57–63.5 Hz and the current harmonic distortion is below 1 %. The power factor is adjustable from 0 (lagging) through 1 to 0 (leading). The inverter efficiency reaches 99.45 %. Cooling is combined, liquid cooling with forced air circulation, the ingress protection is IP54 and the operating temperature is from −20 to +60 °C, with power derating above 40 °C. The MV transformer is built to IEC 60076, with vector group Dy11y11 and KNAN cooling.
DC-side protection includes motorised load-break switches, type 1 + 2 surge protection, reverse polarity monitoring, earth-fault detection and insulation monitoring. Overtemperature protection and an emergency stop button are provided. Options: a low-temperature kit down to −30 °C, fuses of a different rating, enhanced anti-corrosion protection, motorised MV switchgear, UPS, a dedicated auxiliary transformer and seismic reinforcement.
The high power density reduces the number of stations per project and with it the cost of equipment, transport, unloading and site preparation. Factory assembly and testing reduce the amount of work on site and the installation time. The subsystems, namely the MV transformer, the auxiliary power and the DC input configuration, are adapted to the customer requirements. The bidirectional inverter allows the station to be connected to an energy storage system with DC or AC coupling. The stations operate in extreme conditions, in desert climates and at high altitude, in utility-scale PV plants and in hybrid power plants with storage, in 10–35 kV grids.
