| High Light | 48.23kWh Home Backup Energy Storage Battery ，51.2V Residential Energy Storage System ，942Ah LiFePO4 Battery | ||
48.23kWh 51.2V 942Ah LiFePO4 Home Backup Energy Storage Battery.
Designed for residential energy storage projects that require substantially more stored energy from a single battery unit, this LiFePO4 battery provides 48.23kWh of nominal energy from a 51.2V 942Ah platform.
It can be considered for high-consumption homes, larger solar storage requirements and backup projects where smaller 10kWh, 16kWh or 32kWh battery configurations may not provide the desired energy reserve.
A larger battery is not automatically the better choice for every home. The appropriate capacity depends on household electricity consumption, backup requirements, solar generation and the amount of energy that needs to be shifted from daytime to evening use.
Battery capacity and inverter power are different system parameters. The 48.23kWh rating describes how much nominal energy the battery stores, while the inverter determines how much AC load can be supplied at one time.
For this reason, whole-home backup planning should consider battery energy, inverter output, household peak load and required backup duration together.
The choice between 32kWh and 48.23kWh should be based on the amount of stored energy the household actually requires.
If a 32kWh system already meets the expected household energy and backup requirement, moving to 48kWh simply for additional unused capacity may not be necessary.
Solar storage and household electricity are listed among the intended applications in the supplied product information.
When integrated with a compatible hybrid inverter and PV system, the battery can store energy for later residential use according to the operating strategy of the complete system.
The battery itself is not a complete all-in-one residential energy storage system. A compatible inverter and the required electrical components are needed to build the final solar and backup system.

The battery measures 1010 × 850 × 440mm and has an approximate weight of 335kg. These physical characteristics should be considered when selecting the installation location, access route and supporting surface.
The enclosure protection rating is IP54. Final installation should follow the specified protection rating, operating temperature limits and the requirements of the complete residential energy storage system.
The supplied product information also lists thermostatic control, flexible brackets, modular design, remote update and monitoring functions.
The product specification supports up to 15 compatible battery units in parallel, corresponding to a maximum nominal capacity of approximately 723.45kWh based on 48.23kWh per unit.
However, the maximum supported quantity should not be treated as the recommended size for a residential project. Battery quantity should be determined from actual energy demand, inverter capability and the complete electrical system design.
CAN and RS485 communication interfaces are provided for inverter integration.
The supplied parameter sheet lists compatibility with multiple inverter brands, but the exact inverter model should still be confirmed because operating voltage, firmware and BMS communication protocols can differ between products from the same manufacturer.
It depends on the home's actual electricity consumption, backup loads and solar storage requirements. A household with relatively low energy use may not need 48.23kWh of storage, while a higher-consumption residential project may benefit from the additional energy capacity.
Backup duration depends on the average electrical load and usable battery energy. For example, a lower continuous load will provide a much longer operating time than a home using several high-power appliances. Inverter losses and system reserve settings also affect actual runtime.
It can be used as the battery component of a whole-home backup design, but battery capacity alone does not guarantee whole-home operation. The inverter output, household peak load, backup circuit design and required duration must also be matched correctly.
A 48.23kWh battery provides approximately 50% more nominal energy than a 32kWh battery. The larger capacity may be useful for higher consumption or longer backup requirements, while 32kWh may already be sufficient for a lower-demand home.
Inverter size should be selected according to the electrical loads that need to operate rather than battery energy capacity alone. The inverter must also match the 51.2V battery architecture, current requirements and communication protocol.
51.2V LiFePO4 batteries are commonly used in 48V-class energy storage systems. The exact inverter voltage range, charging parameters and CAN or RS485 communication protocol should still be confirmed before installation.
No direct PV connection should be assumed. The battery is designed as the storage component of an energy storage system and should be integrated through a compatible inverter or charging system according to the complete system design.
Yes. The product specification supports up to 15 compatible units in parallel. The inverter, communication configuration and electrical design should be checked before adding additional batteries.
The enclosure is rated IP54. Installation conditions should therefore be selected according to this protection rating, the specified operating temperature range and the requirements of the complete residential system.
Provide daily household electricity consumption, inverter brand and model, maximum backup load, required backup duration, solar PV capacity and planned operating mode. These details help determine whether a 48.23kWh battery is appropriate and confirm system compatibility.
Send us your household electricity consumption, inverter model, solar PV capacity, backup loads and required operating time. We can help check whether 48.23kWh or a smaller residential battery configuration better matches the project.
