Micro-storage and microinverters are booming, and Europe is the key word that must be mentioned.

“Compared to the same period last year, the European export volume has shown a trend of gradual decline, which is a normal seasonal phenomenon. The European household energy storage capacity has continued to grow rapidly year-on-year, and the European energy storage market far from being the industry’s anxiety that it is an already saturated inventory market, but rather has a huge incremental space. The energy storage industry adheres to the long-termism, and the underlying logic of support is the global carbon strategy. 2023 is more like a year for new energy markets to return to rationality.” Donnergy Energy co-founder Peng Yi believes that the true era of energy storage has just begun, and the demand space for microinverters and household energy storage in Europe, North America and other regions will be beyond imagination in the future.

Enough confidence comes from the amazing growth speed of Donnergy Energy.

Although it is a new brand established in 2021, its founder team has been deeply cultivating in the industry for more than 20 years.

In just two years, the company has self-researched more than 20 new products with core patents. Especially the company in the industry's first residential hybrid photovoltaic and storage converter, has become the European market explosion, orders like snowflakes flying.

So far, Donnergy Energy's home storage products are mainly OEM, and it cooperates with the head enterprises in the industry to build production lines and go overseas together. The company has now joined hands with Huizhou Foryou Optoelectronics Technology Co.,Ltd. an electronics manufacturing powerhouse, to share advanced industry technologies in supply chain and intelligent manufacturing.

The company has based on independent intellectual property rights of PCS, EMS, BMS and other electronic control technology and cloud system Internet of Things technology, is committed to providing customers with customized home energy storage, balcony micro-reverse / micro-storage, industrial and commercial energy storage and other suitable for multi-application scenarios of products and solutions.

In the future, Donnergy Energy will also gradually reduce the proportion of OEM and build its own industrial resource pool.

The company has been awarded tens of thousands of balcony microinverter orders in Europe, and the order amount of series products has reached more than 200 million.

Implement Differentiation in The Main Track: to Self-developed The First Residential Hybrid Photovoltaic and Storage Converter

Donnergy Energy has always followed the market demand and national policies, followed the mainstream track in product development strategy, and won the market with original patented technology.

For example, Germany started to implement the KFW442 subsidy policy in September this year for subsidizing photovoltaic, storage and charging systems, and the subsidy program includes the purchase/installation of brand-new charging piles, photovoltaic and energy storage systems.

The combination partner of home storage and new energy vehicle charging piles has become a necessity.

Donnergy Energy therefore aims at the electricity consumption scenarios of households and new energy vehicles, and accordingly developed the first grid-connected residential hybrid photovoltaic and storage converter, which integrates hybrid inverter, vehicle charger, and energy storage battery into a single unit, so as to make its "photovoltaic-energy storage-charging" three-part intermodulation and interaction without any obstacles. At the same time, its highly integrated way of integration can also realize quasi-free installation for users, saving the queuing time of residents' installation declaration as well as installation costs.

This product has been certified by the European grid-connected certification, and is currently in mass production and will be introduced to the market soon.

The company strictly follows ISO 9001, ISO 14001 and industry standards for production operations, and its products include off-grid energy storage inverters, grid-connected and off-grid hybrid energy storage inverters, three-phase energy storage inverters, and so on, with power ranging from 1.5kw~30kw.

Donnergy Energy also provides 50KW~100KW PCS for industrial and commercial energy storage, and has developed wall-mounted and stacked energy storage batteries for household use.

Stacked Off-grid Photovoltaic Energy Storage Integrated Machine

Their photovoltaic grid-tied and off-grid energy storage integrated machine, HEESS PREMIUM 3.0, is equipped with built-in Grade A lithium iron phosphate batteries, with each cell featuring a set of protective devices. It utilizes a large LCD display and supports triple MPPT.

“GH3600TL/GH4600TL/GH5000TL are hybrid photovoltaic inverters for grid-tied and off-grid energy storage, developed by Donnergy Energy for the European market. They have received certifications from the European Union and countries such as Germany, the United Kingdom, Spain, Italy, and Ireland. These inverters are suitable for customizing various photovoltaic energy storage integrated machines and are compatible with all 48V lithium iron phosphate and lead-acid battery groups. They can be used for grid-tied and off-grid applications, have a built-in MPPT controller, and feature UPS functionality to ensure uninterrupted power supply to the load.

Overtaking on the Curve in a Niche Track: Establishing a Proprietary Brand Coverage of Balcony Photovoltaics

The micro-storage field is never short of new products, but finding the right new application scenarios is the key to breaking the game.

Although German residents can install 5KW, 10WK or even higher power grid-connected energy storage systems at home, the installation cost is as high as 2000 to 3000 euros per household, which is too high; the waiting time for installation workers is long, the installation fee is high, and the efficiency is low. Moreover, the roof space of many apartment buildings in the city is limited, making it difficult to install enough photovoltaic panels. 

Microinverter GT600TL/GT800TL

As a super-small distributed photovoltaic system, balcony photovoltaics only need to install solar panels, inverters, and brackets on the balcony, and then connect to the power supply to generate electricity using the limited balcony space.

It’s no surprise that it has become a hot new application scenario for micro-storage in Europe.

In the niche market of home energy storage, Donnergy Energy has established its own brand of balcony photovoltaics with cost-effectiveness and micro-innovation.

The company currently has three micro-inverters, GT400TL, GT600TL, and GT800TL, which have been shipped in large quantities. They are built with MPPT and have DSP control, capable of converting DC to AC, with a peak efficiency of up to 96.7%. They also have an IP67 protection level and support the combination of up to 8 units for grid connection.

The company’s balcony photovoltaic products are mainly divided into three generations.

The first generation is a pure grid-connected micro-inverter, which is compact in size, suitable for various installation scenarios, belongs to the IP67 protection level, and supports up to 8 parallel machines. The second generation is a split-type micro-inverter + micro-storage, which is plug-and-play and easy to install, compatible with 99% of the solar panels and micro-inverters on the market, and also supports battery capacity expansion from 2240Wh to 6720Wh and real-time monitoring and operation via APP.

Donnergy Energy is also developing the third generation of balcony photovoltaics. This is a home energy storage integrated machine with micro-inverter + micro-storage, which can be directly installed on the balcony, and can be remotely set and controlled through the APP and WEB end. 

The year 2024 will be a reshuffling year for the energy storage industry. When the price war begins, only professionalism and innovation can continue to survive. Core technology is the foundation of a company’s survival, and this year will undoubtedly be a leap from 1 to N for Donnergy Energy.

Donnergy Energy already has overseas warehouses in Germany and plans to build production lines abroad. The company’s product plan for next year is to complete the rest of the European market that has not yet been entered, and to accelerate the layout of the American household storage market.
