Application status of INVT photovoltaic inverters in Australian equipment processing plants

1. Introduction of power station

The 100KW distributed power station in Cotmandra, Australia, adopts the iMars series three-phase solution with a total installed capacity of 105KW. The power station was connected to the grid in December 2014 and is used to power the equipment processing plant. At the same time, the power station and the carport are combined to perfectly and effectively utilize the space. The system has been operating normally for 4 months, and the inverter is operating normally, providing a strong guarantee for the normal operation of the factory.

The power station is more than 600 kilometers northeast of Melbourne, Australia's second largest city, where the climate and light conditions are good. The system uses 400 250W monocrystalline silicon modules, which were assembled by a local installer.

Solar energy is absorbed by the PV panels, and the DC power is converted by the inverter and finally output to the equipment processing plant. The remaining power can be connected to the power grid for sale to obtain a return on investment.

3. Introduction of INVT PV Inverter Imars Series Three-phase

INVT iMARSBG series three-phase grid-connected inverter adopts the technology combining advanced T-type three-level topology and SVPWM, providing more flexible system solutions for distributed photovoltaic power generation systems and large-scale ground photovoltaic power stations.

The product has independent dual MPPT to support two groups of unconnected input power, and the maximum input power of a single group is allowed to reach 60% of the total DC power. The AC output power is continuously adjustable from 1 to 100%, and the maximum efficiency of the inverter reaches 98.3%. The internal key components are made of world-class brands, such as IGBT from Infineon, DSP from TEXAS, MCU from PHILIPS, etc. The BUS capacitor uses advanced film capacitors, and the product design uses the most advanced thermal simulation technology, which greatly improves the product life and reliability.

IV. Technical parameters of INVT triple camera:

The power station is configured as follows:

Model BG15KTR: 3 units

Model BG20KTR: 3 units

Total installed capacity 105KW

This power station has effectively solved the power supply problem of the customer's equipment processing plant. Since the electricity price in Australia is relatively expensive, while ensuring the safe and efficient operation of the power station, it also greatly shortens the customer's investment payback period.

V. Conclusion

After installation and stable operation, it has received unanimous praise from customers. Not only because the power station solved the problem of high electricity prices for customers, but also under the unstable Australian power grid, the power station provided relatively stable quality environmentally friendly electricity and ensured the accuracy of equipment processing.
