Build a powerful and flexible home energy storage system with our High-Voltage All-in-One ESS.
Designed with a built-in voltage boost module, the system converts the low-voltage battery input into a high-voltage DC output, making it suitable for high-voltage residential energy storage applications.
With a modular 8kWh capacity per layer, the system can be expanded up to 40kWh with 5 layers, providing flexible energy storage capacity for different household energy needs.
Each battery layer provides approximately 8kWh of energy storage capacity.
The modular stacked design allows you to configure the system according to your actual energy requirements.
Whether you need a compact home backup system or a larger residential energy storage solution, the modular design makes it easy to scale your system.
The system features a built-in DC-DC voltage boost module, eliminating the need for a separate external boost converter.
The battery system can boost the low-voltage battery side to a high-voltage DC output suitable for high-voltage energy storage applications.
This integrated architecture helps simplify system installation and reduces the need for additional external components.
Each battery layer supports up to 4.2kW output power, providing reliable energy for residential applications.
With multiple layers, the system can provide greater energy storage capacity and flexible power configuration.
Ideal for:
Monitor your energy storage system conveniently with built-in WiFi and Bluetooth connectivity.
With smart monitoring, you can check important system information and understand your energy usage more easily.
Monitor:
Stay connected to your energy storage system wherever you are.
The system uses a flexible stackable battery architecture.
Each layer provides approximately 8kWh, allowing you to expand the system according to your energy requirements.
1 Layer → 8kWh
2 Layers → 16kWh
3 Layers → 24kWh
4 Layers → 32kWh
5 Layers → 40kWh
The vertical stacked design helps save installation space while providing a clean and organized energy storage solution.
The system supports parallel connection of multiple battery groups, providing greater flexibility for larger energy storage projects.
It supports:
This allows the system to be configured for different energy storage requirements and project sizes.
Important: Parallel connection should be performed according to the manufacturer's installation requirements. Please confirm compatibility, voltage, BMS communication, and system configuration before connecting different battery systems.
High-voltage energy storage can provide an efficient solution for residential solar energy systems.
By storing excess solar energy during the daytime, the system allows you to use stored energy when solar production is low or household electricity demand is higher.
Solar Panels → Hybrid Inverter → High-Voltage ESS → Home Loads
Store solar energy during the day and use it when you need it.
The system integrates intelligent battery management and multiple protection functions to help ensure stable and reliable operation.
Protection functions may include:
The integrated design helps provide a safer energy storage solution for residential applications.
The High-Voltage All-in-One ESS is suitable for a wide range of home energy applications.
Store electricity and use it when household demand increases.
Store excess solar energy and increase solar self-consumption.
Keep essential household equipment powered during grid interruptions.
Optimize the use of stored energy according to your household electricity demand.
The modular and parallel architecture provides flexible expansion for larger home energy storage systems.
