Server rack batteries are flexible energy storage modules that were once more commonly used in data centres, server rooms, communications base stations and other large-scale facilities, and are usually installed in 19-inch cabinets or racks, where their main purpose is to provide continuous uninterruptible power to core equipment and ensure that critical equipment can continue to operate in the event of a power grid disruption.
With the development of renewable energy storage, the advantages of rack batteries are gradually revealed in the solar energy storage system, and gradually become an important part of the irreplaceable.
Main Functions and Roles of Rack Batteries
Rack batteries are a type of battery pack with high energy density, which can store power from solar, grid and generator in energy storage applications, and its main role and function, mainly contains the following 4 points:
- Uninterruptible Power Supply (UPS):
Provides temporary power to equipment during power interruptions to ensure uninterrupted data and stable system operation.
- Power backup:
When the main power supply is unstable (e.g. voltage fluctuation, instantaneous power failure, etc.), the rack battery can smoothly supply power to prevent equipment damage.
- Load balancing and energy management:
Can be combined with a power management system to achieve load balancing and energy consumption optimisation, improving overall power usage efficiency.
- Reduce home energy costs:
Increases PV self-consumption by storing excess power from the PV system during the day and using energy from the batteries when electricity costs increase.
What Are All The Outstanding Features of Server Rack Batteries?
- Efficient Energy Density:
Rack batteries typically use high energy density battery technology, such as lithium-ion or lithium iron phosphate, to provide longer power delivery and higher performance in a limited space.
- Modular design:
Lightweight and designed to be modular, they can be scaled up or down as needed to accommodate residential and commercial/industrial energy storage scenarios with varying energy needs, and these batteries can be either low-voltage or high-voltage systems.
- Scenario Flexibility:
Standard cabinets or racks can be used for outdoor and indoor installation, easy and quick installation, removal and maintenance, and damaged battery modules can be replaced at will without delaying normal use.
- Intelligent Management System:
Equipped with advanced battery management and monitoring system, it can monitor the battery status, life and performance in real time, and provide fault warning and remote management functions.

Rack Mounted Battery Installation Case Schematic
Rack mounted batteries play an important role in all areas of energy storage. The following are actual application examples:
Residential and commercial buildings:
- Case: In the UK, BSLBATT B-LFP48-100E rack mounted batteries were installed in a large warehouse, with a total of 20 batteries helping the homeowner to store 100kWh of electricity. The system not only saves the homeowner money on their electricity bill during peak energy hours, but also provides a reliable back-up power source during power outages.
- Result: With the storage battery system, the homeowner reduces their electricity bill by 30% during peak energy hours and increases their PV utilisation, with excess power from the solar panels being stored in the batteries during the day.
- Testimonial: ‘Since using the BSL rack-mounted battery system in our warehouse, we have not only reduced our costs, but we have also been able to stabilise our power supply, which makes us more competitive in the market.’
FAQs About Rack Batteries
Q: How do I install a rack battery?
A: Rack batteries are very flexible and can be installed in standard cabinets or mounted on the wall using hangers, but either way, it requires a professional technician to operate and follow the drawings and installation instructions provided by the manufacturer for installation and wiring.
Q: What is the battery life of a server rack?
A: The battery life depends on the total load power. Typically, in data centre applications, standard server rack batteries are required to provide hours to days of standby time; in home energy storage applications, server rack batteries are required to provide at least 2-6 hours of standby time.
Q: How are rack batteries maintained?
A: Under normal circumstances, lithium iron phosphate rack batteries do not require maintenance, but bare mounted rack batteries need to be periodically checked for loose or corroded connections. In addition, keeping the ambient temperature and humidity of the rack battery within the appropriate range will also help to extend battery life.
Q: Are rack batteries safe?
A: Rack batteries have a separate BMS inside, which can provide multiple protection mechanisms such as over-voltage, over-current, over-temperature or short-circuit. Lithium Iron Phosphate batteries are the most stable electrochemical technology and will not explode or catch fire in the event of a battery failure.
Q: How do rack batteries match my inverter?
A: Each rackmount battery manufacturer has a corresponding inverter protocol, please refer to the relevant documents provided by the manufacturer such as: instruction manual, inverter listing documents, etc. before purchase. Or you can contact our engineers directly, we will give you the most professional answer.
Q: Who is the best manufacturer of rackmount batteries?
