| High Light | 32kWh Residential Solar Backup Battery ，51.2V LiFePO4 Home Battery ，628Ah Residential Energy Storage Battery | ||
32kWh 51.2V 628Ah LiFePO4 Residential Solar Backup Battery.
Designed as the battery storage component of a higher-capacity residential energy storage system, this LiFePO4 battery provides 32kWh of nominal energy from a 51.2V 628Ah platform.
It is intended for residential projects where smaller 5kWh, 10kWh or 16kWh battery configurations may not provide enough stored energy for the desired solar self-consumption or backup duration.
Battery capacity should be selected according to actual household energy use rather than choosing a larger battery simply because more capacity is available.
A 32kWh-class battery can be considered when a residential project requires more stored energy for evening consumption, longer backup duration or a larger solar storage requirement than smaller battery configurations can provide.
Backup duration depends primarily on the average electrical load. The examples below are simple nominal energy comparisons and are not guaranteed operating times.
Actual backup time will differ because of inverter losses, battery operating limits, reserve settings and changing household loads.
The supplied product information lists solar storage and household electricity among the intended applications.
When connected to a compatible hybrid inverter and PV system, the battery can be used as the storage component of a residential system designed to store solar energy for later household use or backup operation.
The battery is not a complete all-in-one residential energy storage system by itself. The inverter, solar array and required electrical components need to be selected separately according to the project design.
The choice mainly depends on how much stored energy the household actually requires.

The battery measures 720 × 811 × 489mm and has an approximate weight of 247kg. The installation location and supporting surface should therefore be considered as part of the residential system design.
The enclosure protection rating is IP54. Final installation conditions should follow the specified protection rating, temperature limits and requirements of the complete electrical system.
The product information also describes a modular design with flexible brackets, thermostatic control, remote update and monitoring functions.
Yes. The supplied specification supports up to 15 compatible battery units in parallel.
This provides an expansion path for projects that later require more storage than one 32kWh battery can provide. Fifteen units represent up to 480kWh of nominal battery capacity based on 32kWh per unit.
For a residential installation, however, the practical number of batteries should be determined from the actual energy requirement, inverter capability, communication configuration and electrical design rather than the maximum parallel quantity alone.
The battery provides CAN and RS485 communication for connection with compatible inverter systems.
The supplied parameter sheet lists multiple inverter brands, but compatibility should be checked using the exact inverter model because voltage settings, firmware and BMS communication protocols can differ between products from the same brand.
It depends on the home's electricity consumption, backup loads and required operating time. A single battery provides 32kWh of nominal energy, but actual system suitability should be determined from the household's real energy requirements.
Runtime depends on average load. As a nominal comparison, 32kWh corresponds to about 16 hours at 2kW, 8 hours at 4kW or 4 hours at 8kW before considering inverter losses, battery reserve settings and changing loads.
It may form part of a whole-home backup system, but battery capacity alone cannot determine this. The inverter output, household peak load, backup circuit design and required operating time must also be considered.
A 32kWh battery provides approximately twice the nominal stored energy of a 16kWh-class battery. The larger capacity may be useful when longer backup or more solar energy storage is required, while a smaller battery may already be sufficient for lower household demand.
Inverter size should be determined by the electrical loads that need to operate, not by the battery's 32kWh energy capacity alone. The inverter must also match the battery voltage, allowable current and communication protocol.
51.2V LiFePO4 batteries are commonly used in 48V-class energy storage systems. The exact inverter operating voltage, charging settings and CAN or RS485 communication protocol should still be confirmed before installation.
The battery is designed as the storage component of an energy storage system. A compatible inverter or charging system is required between the PV array and battery according to the complete system architecture.
Yes. The specification supports up to 15 compatible units in parallel. The final quantity should be checked against the inverter and complete electrical system before expansion.
The enclosure is rated IP54. Installation conditions should therefore be selected according to this protection rating, the specified operating temperatures and the requirements of the complete residential energy storage system.
Provide the inverter brand and model, daily household electricity consumption, maximum backup load, required backup duration and solar PV capacity. These details help determine whether 32kWh is an appropriate storage capacity and confirm system compatibility.
Send us your household electricity use, inverter model, backup loads, solar PV capacity and required backup time. We can help check whether a 32kWh battery or a smaller residential storage configuration better matches your project.
