EAST 1500V1.25MW photovoltaic inverter launched to the market with leading technical indicators

In recent years, my country's photovoltaic power generation subsidies have been reduced year by year. The "Energy Development Strategic Action Plan (2014-2020)" has long proposed that photovoltaic power generation is expected to achieve grid parity by 2020. Therefore, reducing system costs and improving power generation efficiency have become the mainstream of the development of the photovoltaic industry. Easy Energy (300376) has actively considered and promoted technological progress in the industry, and recently launched a 1500V 1.25MW (model EA1250KHV) photovoltaic inverter.

Performance characteristics

01EA1250KHV adopts Type I three-level technology with a maximum efficiency of 99%, which increases power generation.

02 Modular design concept, supports redundant sleep function, single module runs under light load, and the whole machine runs under heavy load. The modules can run independently, which improves power generation efficiency and effectively extends the life cycle.

03 Dual-core DSP digital control, faster computing speed, higher precision, safer and more reliable system operation.

04Supports adjustable reactive power, and the power factor is adjustable from leading 0.8 to lagging 0.8.

05The system incorporates damping to fully suppress oscillations, making the grid more adaptable.

06It has the function of power harmonic filtering to improve the output power quality.

07 Intelligent terminal, integrated SVG function, fully responds to grid dispatch, reduces initial investment

Solution

1500V centralized end-to-end solution

EAST provides 1500V centralized end-to-end solutions, from combiner boxes, inverters, containers, to integrated box-to-box transformers (container and step-up transformer integrated into one), providing customers with a full range of services.

●Compared with the traditional 1000V system, EA1250KHV increases the DC input voltage to 1500V, reduces the DC side current, and can reduce the investment cost of DC cables and combiner boxes.

●The output voltage on the AC side is increased, which can reduce current and power loss.

● Improved the overall efficiency of the system, increased power generation, and reduced system investment costs. The larger the scale of the power station investment, the more obvious the advantages will be, increasing customer return rate.

At present, the advantages of 1500V photovoltaic systems are gradually recognized by the industry. Domestic demonstration power stations have been completed one after another, and overseas markets such as India and North America have had mature applications. The EA1250KHV photovoltaic grid-connected inverter developed by Eastar has undergone rigorous performance/functional testing, limit/white box testing, reliability testing (short circuit testing, transportation testing, 55°C ambient temperature testing, etc.), and successfully completed the CQC new energy standard "NB-T32004-2013 Photovoltaic Power Generation Grid-Connected Inverter Technical Specifications" and China Efficiency Certification "CNCA/CTS0002-2014 Photovoltaic Grid-Connected Inverter China Efficiency Technical Conditions" testing.

As an excellent inverter manufacturer, YST provides customers with a full range of 3KW~1.25MW string, centralized, and distributed photovoltaic inverters and complete system solutions.
