Guruiwate new energy high-performance inverter winning new urban rooftop photovoltaic project in Turpan

Recently, the city of Turpan new rooftop photovoltaic power plant project a bidding ends. Guruiwate (GREAT) new energy inverters Growatt 10000-20000 from numerous domestic and international brands stand one fell swoop, in accordance with the tender content Guruiwate (GREAT) new energy sources will provide the project a total of 8.5MW more than 500 photovoltaic inverters.

    The construction of new energy projects as the city of Turpan important step, which will become the largest and most comprehensive technology integration and building integrated solar energy projects, programs in ten years in three phases. Rooftop PV installed in an initial area of ​​the roof of the building, covering the number of residents 7016, about 2.5 million people living persons, more than 300 public buildings and civil buildings.

    Turpan new urban projects, using Guruiwate distributed inverter (10kW ~ 20kW) to complete the entire project, is the first truly distributed photovoltaic power plants, truly a multi-point grid, the nearest grid and accounted for 70% PV (30% higher than conventional requirements), the entire system is very forefront of technology integration and high-end. The significance of the project, completely breaking the previous pair of photovoltaic grid is "utilization is low, intermittent electricity and garbage cause electric shock grid" is defined, for the city's photovoltaic applications out of a new route, leading the inverter industry to the grid-friendly, adaptive grid taking the successful step.

    Guruiwate new energy photovoltaic inverter applications distributed urban photovoltaic applications will bring more power gains, higher system stability and better maintainability, mainly has the following advantages:
First, the grid-friendly.

    Photovoltaic characteristics inherently unstable, when the PV plant during power when the grid voltage and frequency will be with the circuit transmission characteristics of the user load fluctuates. Guruiwate inverter via adaptive active control and reactive power compensation, which can automatically help suppress voltage fluctuations and the effective protection of low voltage ride through, but also can effectively avoid the grid frequency drift, to help stabilize the grid.

    Guruiwate inverter also has a remote reactive power regulation functions and remotely turn off function, can match the smart grid intelligent remote monitoring and control. Second, multi-generation MPPT solution increases, the nearest grid system losses low. The component maximum power point tracking (MPPT) to ensure reliable power for the components use; MPPT scheme more and more for each string for maximum power point tracking, to avoid inconsistencies caused by the overall tracking efficiency losses, in order to ensure the reliability of the power generation system, lead to higher power output.


    And a large power plant different desert, urban construction (factories, supermarkets, schools, etc.) is the user of electricity, as well as long-distance transmission without boost, you can improve the efficiency of photovoltaic power generation. Guruiwate as a grid-friendly photovoltaic inverter supports the nearest grid and multi-point grid, avoiding the step-up circuit transmission and resulting energy loss.
