Application of INVT photovoltaic inverter in Australian government offices

Abstract: Photovoltaic inverters are an indispensable part of solar power stations. The quality of the inverters directly affects the power generation and quality of the power station. Stable power generation guarantees the power supply and normal operation of the factory. At the same time, the quality of electricity also plays a vital role in the precision and quality of equipment processing. This article mainly introduces the application of INVT inverters in the Tasmanian government office in Australia.

1. Introduction of power station

The 10KW distributed household power generation in Tasmania, Australia, uses the iMars series three-phase solution. The power station was connected to the grid in December 2014 and used in the government road maintenance office. After the system was installed, it has been running normally for 10 consecutive months, and the inverter is running normally, providing a strong guarantee for the normal operation of the office.

The power station is located in the beautiful and quiet state of Tasmania, Australia, where the climate and light conditions are good. The system uses 40 250W monocrystalline silicon modules, which were assembled by a local installer.

The solar panels absorb sunlight, and the DC electricity is converted by the inverter and finally output to the office for use. The remaining electricity can be added to the grid and sold 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. INVT Triple-Camera Technical Parameters

The power station is configured as follows:

Model BG10KTR: 1 set

Total installed capacity 10KW

This power station has effectively solved the power supply problem of the customer's office in a remote location. 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.
