SolarFam SF-320 LiFePO4 Battery 12.8V 320Ah – 4096Wh Bluetooth & WiFi

The SolarFam SF-320 12.8V 320Ah LiFePO4 battery is a powerful lithium battery with an energy capacity of no less than 4096Wh. Thanks to its high capacity, integrated Battery Management System, and compact dimensions, this battery is ideal for RVs, trailers, boats, solar power systems, off-grid applications, and other 12V installations.

The SF-320 is equipped with Bluetooth and Wi-Fi, allowing you to monitor key battery data via a compatible app. Additionally, the battery features a built-in heating function for use in low temperatures.

LiFePO4 Technology

The SolarFam SF-320 uses LiFePO4—lithium iron phosphate. This battery technology combines high usable capacity with a long service life and relatively low weight.

According to the manufacturer, when used correctly, the battery can achieve a lifespan of up to approximately 6,000 charge and discharge cycles.

320Ah capacity and 4,096Wh energy

With a nominal voltage of 12.8V and a capacity of 320Ah, the SolarFam SF-320 has a nominal energy capacity of 4096Wh.

This makes the battery suitable for applications that require a lot of energy over an extended period, such as lighting, refrigerators, electronics, pumps, and inverters.

Integrated Battery Management System

The SolarFam SF-320 is equipped with an integrated BMS—Battery Management System. This system monitors the battery and protects the LiFePO4 cells from conditions that could damage the battery.

BMS Protections

• Overvoltage Protection
• Undervoltage Protection
• Overcurrent protection
• Short-circuit protection
• Temperature protection
• Cell balancing

Bluetooth and Wi-Fi monitoring

The SF-320 features Bluetooth and Wi-Fi. This allows you to view important battery data via a compatible mobile app.

This makes it easy to check the battery’s status without having to connect measuring equipment directly to the battery terminals.

Built-in heating function

The SolarFam SF-320 features a built-in heating function. This function supports the use of the LiFePO4 battery at low temperatures.

LiFePO4 cells should not normally be charged at very low cell temperatures. The heating function helps bring the battery up to a suitable temperature in cold conditions.

High current output

The SF-320 is designed for applications where high currents may occur. According to the technical specifications, the maximum current is 300A for up to 5 seconds.

This allows the battery to be used in systems with high-power 12V equipment and inverters, provided that the system, wiring, fuses, and connections are suitable for this purpose.

Parallel Connection Possible

When more capacity is needed, suitable SolarFam SF-320 batteries can be connected in parallel.

Note: According to the SF-320’s technical specifications, series connection is not permitted. Therefore, do not use this battery in a series connection to create a 24V, 36V, or 48V battery bank.

Compact and robust housing

Despite its high capacity of 320Ah, the SolarFam SF-320 has compact dimensions of just 353 x 198 x 250 mm.

It weighs approximately 27.2 kg. The housing is made of ABS and PC, and the electrical connections are made via sturdy M8 connectors.
