Big news! Growatt's commercial and industrial energy storage inverters are now fully realized

In order to cope with climate change and achieve energy transformation, countries around the world are vigorously developing renewable energy. However, renewable energy generation generally has intermittent and volatile problems, which need to be regulated by energy storage technology. The development of energy storage technology has become an important part of the energy transformation of various countries.

On November 11, Growatt released the WIT series of new industrial and commercial energy storage products at the 9th China International Solar Storage and Charging Conference. Mr. Yuan Zhimin, Product Director of Growatt, introduced at the press conference: "The power system built with a high proportion of renewable energy is characterized by randomness, volatility, and intermittency, which leads to a large demand for system regulation resources. The difficulty of large-scale and long-term power balance in the system has increased significantly, which has brought great challenges to the stability of the power grid. The energy storage system is required to provide flexible regulation and key support. Growatt's WIT industrial and commercial energy storage products are characterized by high energy, flexibility, safety, and intelligence. They have unique advantages in improving the flexibility of the power system and ensuring the safety and stability of the power grid."

After years of technological accumulation, Growatt has made great strides in the field of energy storage and is fully embracing the era of global energy storage.

01

Leading technology, safe and reliable

High Energy:

Growatt's WIT industrial and commercial energy storage products adopt a multi-channel MPPT design to support complex application scenarios and reduce photovoltaic string mismatch losses. The battery charge and discharge efficiency is as high as 98%, allowing every bit of energy to be efficiently utilized. The powerful load-carrying capacity supports motor loads and 100% three-phase unbalanced loads, and can be overloaded by 110% for a long time.

Smart:

In the era of high-power components, the compatibility of inverters is particularly important. WIT's industrial and commercial energy storage products allow a maximum input current of 16A per string, which is suitable for high-power components; they support multi-machine parallel connection, making system expansion easier and more convenient; the multi-channel string design eliminates the need for photovoltaic combiner boxes, saving system investment costs to the greatest extent.

Safety:

With the development of energy storage technology, product safety has become a top priority. WIT's industrial and commercial energy storage products adopt a fuse-free design, which is safe and maintenance-free; the whole machine has an IP66 protection level design, which is waterproof and dustproof, and can adapt to various harsh and complex application environments; the AC and DC secondary lightning protection module design is extremely safe; the precise DC arc protection technology eliminates the hidden dangers of power station fires.

intelligent:

Intelligent string monitoring to accurately locate faults; intelligent IV curve scanning to diagnose the health status of the power station with one click and provide a diagnostic report; big data intelligent early warning analysis and remote intelligent operation and maintenance to minimize power generation losses; intelligent reactive power compensation to reduce equipment investment in reactive power compensation cabinets while avoiding fines caused by excessive power factor.

From household to industrial and commercial use, comprehensive efforts

The global energy storage market is growing at an unprecedented rate. According to a report by Frost & Sullivan, by the end of 2021, the newly installed capacity of global energy storage projects in operation was 25.2GW. It is estimated that the global new energy storage capacity will have a compound annual growth rate of 83.8% in the next five years, and the global energy storage installed capacity will reach 528.4GW by 2026.

As early as 2015, Growatt began to expand its household energy storage business. It is one of the earliest companies in China to enter the field of photovoltaic energy storage and one of the few companies in the industry that provides users with integrated solutions of energy storage inverters and self-produced batteries. The launch of Growatt's industrial and commercial energy storage products is another important measure for Growatt's all-round layout in the field of energy storage.

Full-scenario layout, deepening globalization strategy

As energy storage is rapidly becoming popular around the world, it has become another super track in the wave of energy revolution.

Growatt will provide customers with a variety of energy storage system solutions covering household and industrial and commercial use, including grid-connected photovoltaic energy storage, off-grid photovoltaic energy storage and photovoltaic reserve energy storage, targeting different application scenarios of global customers. It will also deeply integrate photovoltaics, energy storage and charging piles, and adopt intelligent joint adjustment and linkage control methods to maximize the proportion of photovoltaic self-generation and self-use, and create a complete integrated photovoltaic storage and charging solution for users.

In this century-long test of the country's "dual carbon goals", Growatt has always practiced the concept of sustainable development, taken technological innovation as the guide, and committed to the research and development of key technologies such as photovoltaics, energy storage systems, and smart energy management, actively promoting the country's dual carbon, green economic transformation and the construction of a new power system.
