On February 18-19, ENEX Poland was held at the T Targi Kielce Exhibition Congress Centre. Chint Power Systems presented its full-scenario PV and storage system solutions at Booth NO.7-D02 and launched the new 1.6MW/3.3MWh C&I energy storage system, which will help Poland's energy transition with innovative technologies.

With a superior light resource of 1,350 kWh/m2 per year, coupled with the government's continued increase in renewable energy incentives, Poland has been the fifth largest solar market in Europe, with distributed and C&I projects going hand in hand. By the end of 2024, Poland's cumulative PV installations will have exceeded 20GW.

C&I and Utility PV Solution

Chint Power Systems' 275kW and 350kW string inverters attracted a large number of exhibitors, especially the 350kW string inverter, which was widely praised by customers for its outstanding product performance:

·Supports 15-channel MPPT intelligent tracking, which can simultaneously optimize the power generation efficiency of 30 strings of PV arrays and solve the problem of power generation loss caused by shadow shading;

·99% conversion efficiency, increasing annual power generation by more than 3% compared with conventional products;

·Breakthrough 45℃ high-temperature full power operation, fearless of deserts, mudflats, and other harsh environments, effectively enhancing system power generation efficiency.

For commercial PV, Chint Power Systems exhibited 50/60kW and 100/125kW string inverters. Chint Power Systems' 100/125kW inverters have significant advantages:

·12-channel MPPT precise control system, flexibly adapting to PV arrays of different orientations/specifications, cracking the design problems of distributed projects.

·Supports up to 1.5 times module overmatching design, effectively enhancing power generation revenue in rainy and hazy weather, and increasing system utilization rate by 30%.

·Intelligent operation and maintenance platform realizes remote monitoring + power generation prediction, making operation and maintenance more convenient and efficient.

Innovative Energy Storage Solutions to Solve Energy Challenges 1.6MW/3.3MWh Energy Storage System

In this exhibition, Chint Power Systems launched a new large-scale C&I 1.6MW/3.3MWh energy storage solution, which has more significant advantages in small ground power stations and large-scale C&I scenarios!

·Plug and Play, Efficient Deployment: Adopting a 20-foot standard container integration design, the AC/DC system is integrated and conveniently transported, and the workload of on-site construction and debugging is reduced by about 50%, which significantly shortens the project delivery cycle.

·Solar-storage synergy cost reduction and efficiency: solar-storage and low-voltage common transformer coupling technology, improve energy conversion efficiency by 4%, and equipment cost reduction of about 5%, to achieve a higher return on investment.

·Intelligent management, precise control: a cluster of one management design, eliminating inter-cluster loop current, a capacity loss of up to 7% less than the centralized type, stable and efficient operation of the system.

·Multi-protection, safe, and reliable: Pack-level and system-level double security, core-level aerogel insulation technology, system-level thermal runaway protection design, ensuring 'zero explosion' risk.

Residential and Utility Energy Storage Systems

Chint Power Systems has further upgraded its energy storage product matrix in response to the demand for grid stability and the trend of energy structure transformation in Poland. At the exhibition, Chint Power Systems' single-phase and three-phase residential energy storage solutions, as well as its 5MWh liquid cooling energy storage system solution, attracted strong interest from visitors.

The core products of residential inverters are hybrid inverters and residential storage batteries. The battery adopts a modular stacked design, which makes wiring-free installation more convenient; the Hybrid inverter is equipped with AFCI function and 5 basic operating modes as standard, which is characterized by high yield, high performance, and high reliability, and can adapt to various harsh installation environments; the whole system can provide users with stable and reliable power, and support seamless switching between on-grid and off-grid so that users can use electricity without any worry.

Chint Power Systems' 5MWh liquid cooling energy storage system continues to provide stable support for large-scale ground-mounted power stations in Poland. The standard 20-foot container can hold 5MWh, effectively reducing the cost per watt-hour; Intelligent liquid cooling temperature control technology can realize the temperature difference between Pack-level cores <1.5℃, and the temperature difference between system-level cores <2℃; omnidirectional, full-area safety design ensures the safety and stability of the system from multi-dimensional aspects such as electrical, structural, operational, personal, and fire protection. 

With the double explosion of the Polish PV and energy storage markets, Chint Power Systems will inject surging power into Europe's green energy transformation with a matrix of more efficient, smarter, and more reliable products, and work together with its global partners to achieve a 'zero-carbon future'.
