For families who want to install a solar battery energy storage system, they will face the problem of how to choose an inverter and battery.
There are many types of inverters and batteries with complex technical parameters; in addition, more installation time is required during on-site wiring installation and debugging of inverters and batteries.
In order to solve this problem, some leading technology companies began to try to integrate inverters and batteries into one product – thus all-in-one energy storage system came into being.
What is all-in-one energy storage system?
The all-in-one energy storage system is an integrated system that places photovoltaic inverters, batteries and controllers inside.
As a new generation product in the field of energy storage, the all-in-one energy storage system is easy to use, plug-and-play, and can greatly save installation time; it is also more technically mature, the product is more refined, and some performances have been improved.
Evolutionary stages of all-in-one energy storage system
1. Split machine: In the early days, the energy storage system was designed as a split machine, with independent energy generation, storage and conversion components. These systems require complex installation and have limited flexibility in terms of scalability and integration. This approach presents challenges in terms of system efficiency, overall cost, and maintenance.
2. Integrated systems: As technology advances, energy storage systems begin to integrate various components into a single unit. This integration makes installation easier, increases efficiency and simplifies operation. Integrating components such as batteries, inverters and power management systems into a single device enhances the overall performance of the energy storage system. However, they still lack the ability to provide comprehensive solutions for all energy storage needs.
3. All-in-one energy storage system: The latest stage of energy storage development is the development of integrated energy storage solutions. These systems combine energy generation, storage and conversion functions into a single device, seamlessly integrating all components required for efficient energy management.
All-in-one energy storage systems utilize advanced technologies such as lithium ion batteries, lithium ion BMS, inverters, and intelligent energy management systems. This integration brings benefits such as increased overall system efficiency, improved power quality and stability, enhanced scalability, and reduced installation and maintenance costs
All-in-one energy storage system installation cost analysis
In terms of cost, all-in-one energy storage system can be divided into four aspects: battery cells, energy storage inverters, component systems, and installation costs.
1. Battery core cost: Battery core is the core of the energy storage system, accounting for about 45-50% of the cost. You can click our top 10 energy storage battery manufacturers in the world to get more information.
2. Cost of energy storage inverter: Energy storage inverter can control charge and discharge and convert AC to DC, accounting for about 10-15% of the cost;
3. Component system cost: The component system, that is, the photovoltaic system, is used for solar power generation, accounting for about 20-25% of the cost;
4. Installation cost: The current installation cost has increased from 10,000 in 2021 to about 20,000, accounting for 15-20%.
Here we emphasize the cost of battery cells. The technical routes for energy storage batteries include lithium-ion, lead-acid batteries, flow batteries, etc.
Currently, lithium iron phosphate batteries are more expensive than ternary lithium batteries due to their high safety and long battery life cycle. It meets the design requirements of energy storage batteries and is the mainstream development route of energy storage batteries.
What configuration is suitable for all-in-one energy storage system?
Normally, if there are 7 to 10 electrical appliances that consume daily power, the total power of the power generation system is best around 5KW. The price of a 5KW home photovoltaic power generation system is around 90,000 RMB;
If the number of daily power-consuming appliances reaches 12 to 15, especially if smart homes, electric vehicle charging, etc. are also considered, it is best to choose a 10KW power generation system, which costs around 180,000 RMB.
It should be noted that if it needs to be used in combination with photovoltaics. The installation of home solar photovoltaics requires many details, including roof structure, roof angle and orientation, load-bearing capacity, etc. Every detail will affect future power generation efficiency and usage experience.
Therefore, before installation, you must find a professional team to design a targeted home energy storage solution.
