All-In-One is the major trend for HOME-ESS, and in the future it is estimated to capture a significant portion of the market share which is currently dominated by split systems. Currently, the primary mode of shipment is split systems. However, various issues with split systems such as complicated installation and instability are increasing day by day giving customers lot of problems.
The HOME-ESS All-In-One has shown rapid sales growth in the first half of 2022~2023. For example, SOLAX All-In-One had sales of nearly 2 billion yuan in 2022, which is almost 20 times the sales revenue of 2021.
They are in a clear competitive relationship between All-in-One and Split systems and customer has to choose one of them between them in most of the cases. These two systems usually cannot coexist together.
First of all, the core technology included in Home-ESS All-In-One products does not substantially differ from split systems. All-In-One primarily represents an innovation in terms of exterior design, adopting an intensive design approach to improve installation convenience and product aesthetics. This approach aligns better with household scenarios that require smaller footprints and higher integration.
The development direction of products must undoubtedly focus on higher standardization, greater efficiency, and improved reliability. All-In-One holds a significant advantage over split systems in these aspects.
Today split systems are gradualy being phased out and Home-ESS products demands are growing.
All-In-One represents a prefabricated solution, where the integration of battery packs and inverters is completed at the factory, resulting in the highest installation efficiency. This directly impact the division of labor and profit distribution in the industry chain.
Split systems essentially involve separate production of inverters and battery packs, requiring integrators to source them separately. Therefore, their primary customers are integrators, and integrators have the flexibility to choose which products to purchase which means that they are the first party in this context.
Moreover, due to the ongoing consumption of demand for split systems by All-In-One, Home-ESS manufacturers who are less sensitive to the All-In-One trend will face increasingly fierce competition, making their situation more challenging.
Now let’s take a look at a few benchmark All-In-One cases:
SOLAX-ESS G4
SOLAX is one of the early enterprises in the industry to introduce and successfully sell All-In-One energy storage products. They primarily sell to regions like Germany and Japan, giving them a significant advantage in market pioneering.
SOLAX Home-ESS All-In-One primarily consists of three components: energy storage inverter, energy storage battery, and a connecting box (Mate box). All of these components are independently developed, designed, and produced by SOLAX.
This All-In-One product has transformed the original cable connections into plug-and-play connections, adopting an intensive design approach to improve installation convenience and product aesthetics.
Additionally, Mate box addresses the issues related to client selection and procurement of safety devices, while also reducing user installation complexity and simplifying the installation steps. In 2022, this product achieved sales revenue of 19.66 billion yuan, a significant increase compared to the 1.02 billion yuan in revenue from integrated energy storage in 2021, indicating substantial sales growth.
Tesla Powerwall Series
The Tesla Powerwall Plus is the latest generation of the Powerwall, and it represents an upgrade from the Powerwall 2. Currently, it is only available for sale in the United States. The product’s performance is similar to that of the Powerwall 2, with a capacity of 13.5 kWh and AC coupling. However, it has the additional feature of a solar inverter integrated into the system, making it an All-In-One solution.
With this feature, the Powerwall Plus can directly integrate with a solar power system without the need for an additional inverter. This makes the installation process simpler compared to the Powerwall 2, as it eliminates the need for an extra inverter.
HUAWEI
HUAWEI has also introduced the Power-M Home-ESS All-In-One product.
HUAWEI’s All-In-One products have outperformed their own split energy storage products.
SigenStor
SigenStor have similarly made All-In-One products.
