Product Description

High-Capacity Residential Solar Storage

51.2V 300Ah 15.36kWh LiFePO4 Home Energy Storage Battery

High-capacity low-voltage battery storage for residential solar self-consumption, home backup and compatible off-grid energy systems.

15.36kWh Residential Energy Storage

The Chalongfly 51.2V 300Ah LiFePO4 battery provides 15.36kWh of nominal energy for homes requiring substantial solar energy storage and backup capacity.

It is designed for compatible 48V-class hybrid and off-grid inverter systems and can store photovoltaic energy for nighttime use, backup power and increased solar self-consumption.

Smart BMS, inverter communication, monitoring and system expansion can be configured according to the final residential ESS project.

High-Capacity Home Battery

The 15.36kWh nominal capacity provides substantial energy storage for photovoltaic self-consumption, nighttime household loads and backup-power applications.

Solar Self-Consumption & Backup

Daytime Solar PV supplies household loads and stores surplus energy in the battery.

Evening Stored solar energy can support household consumption after photovoltaic production falls.

Grid Outage A compatible backup inverter can use battery energy to support selected household loads.

Smart BMS Protection

Overcharge protection
Over-discharge protection
Over-current protection
Short-circuit protection
Temperature protection
Cell voltage monitoring
Cell balancing
SOC and battery operating-status management

Inverter Communication

Correct communication between the battery BMS and inverter is essential for reliable residential energy-storage operation.

CAN	Available According to BMS Configuration
RS485	Available According to BMS Configuration
Inverter Protocol	Confirmed According to Inverter Brand and Model

Battery-Only ESS Architecture

Inverter Matching Required

This product is positioned as a battery energy-storage unit. Hybrid inverter, MPPT solar charger, AC transfer equipment and photovoltaic modules are supplied separately unless specifically included in the confirmed project configuration.

Expandable Energy Storage

Multiple battery units can be engineered for higher-capacity residential ESS projects when the BMS, inverter protocol and parallel-system architecture support multi-battery operation. The maximum number of parallel batteries is confirmed according to the final system design.

Typical Applications

Home Solar Storage Store surplus photovoltaic energy for evening and nighttime household use.	Home Backup Power Battery energy for compatible inverter-based backup systems during grid interruptions.
Off-Grid Homes High-capacity storage for homes relying on photovoltaic and other renewable-energy sources.	PV Self-Consumption Increase local use of solar generation instead of exporting all surplus energy to the grid.

Frequently Asked Questions

How much energy does the battery store?

The 51.2V 300Ah battery provides 15.36kWh of nominal energy.

Does it include an inverter?

The standard configuration is a battery energy-storage unit. A suitable inverter can be supplied separately according to the project.

Can it communicate with my inverter?

CAN or RS485 communication can be configured, but compatibility must be confirmed from the inverter brand, model and required battery protocol.

Can several batteries be connected together?

Parallel expansion can be supported according to the final BMS and inverter architecture. The approved maximum number of batteries must be confirmed before installation.

How long can it power a house?

Runtime depends on usable battery energy, inverter efficiency and the average household load. Provide the expected loads for an accurate backup-time calculation.

What information is required before ordering?

Please provide the inverter model, solar-system size, household average and peak load, required backup time, communication protocol, installation conditions and required total battery capacity.
