As more homes and businesses switch to solar power and backup systems, lithium batteries have become the most preferred choice for energy storage. They are reliable, long-lasting, compact, and require very little maintenance.
Both types have their own benefits and uses. Your decision depends on factors like available space, power requirements, budget, and future expansion. In this blog, we will help you understand the difference between the two and guide you toward the best choice based on your needs.
What is a Wall-Mounted Lithium Battery?
A wall-mounted lithium battery is just that a small, flat battery unit that may be installed indoors or out. These are streamlined, fashionable, and ideal for compact offices or residences with little floor area.
Key benefits:
- Space-saving: Mounts on the wall like an inverter or switchboard
- Looks modern: Most models have a clean, stylish design
- Safe and compact: Sealed units with built-in BMS (Battery Management System)
- Easy to install: Lightweight compared to lead-acid or rack-mounted batteries
Wall-mounted batteries typically range from 5kWh to 10kWh in capacity and are suitable for users with medium energy storage needs.
What is a Rack-Mounted Lithium Battery?
Rack-mounted lithium batteries are generally used in larger setups where more power is needed — like big homes, offices, shops, or even factories. These batteries come in modular blocks and are installed in a battery rack or cabinet, similar to how servers are arranged in a data center.
Key benefits:
- Scalable system: You can stack multiple battery units as your need grows
- High capacity: Each module adds more storage — ideal for high-load usage
- Organized layout: Neat cable arrangement and ventilation
- Used in industrial & commercial setups: More power-hungry operations
- Easy to service: Individual battery units can be replaced or checked
Which One Should You Choose?
Your choice depends on your space, energy usage, and budget:
- The wall-mounted lithium battery is ideal for homeowners with modest space requirements and simple energy backup requirements. It can power your house effectively, looks modern, and conserves floor space.
- If you are running a business, have a large household, or plan to expand your solar setup in the future, then rack-mounted batteries are the smarter choice. They give you flexibility and high power storage without replacing the fullsystem later.
Think about your energy needs 2–3 years from now. If your power usage is likely to grow, rack-mounted batteries offer more freedom to scale up without redesigning your system.
Interestingly, many of the Top 10 Lithium battery Manufacturers in India and abroad are now offering both types of batteries to suit different customers. Brands like Loom Solar, Livguard, Exide, and international giants like BYD and LG Chem are making it easier to choose based on application rather than compromise.
Safety and Design Differences
Both wall-mounted and rack-mounted lithium batteries come with built-in safety features like BMS, overcharge protection, and thermal control. However, rack-mounted batteries often have better airflow and cooling options, especially when placed in battery cabinets.
On the other hand, wall-mounted units are more visible, so they are designed to look sleek and stylish almost like a modern appliance. Some models even come with display screens to show charge level and health status.
If aesthetics matter to you for example, in a living room or visible wall wall-mounted units may look more appealing.
Budget and Installation Cost
Wall-mounted batteries are usually cheaper for smaller setups (like 5kWh) and easier to install. You just need a solid wall, some bolts, and basic wiring.
Rack-mounted systems require more setup cost racks, wiring channels, proper ventilation, and sometimes even dedicated battery rooms. However, the cost per kWh can be lower when buying multiple battery modules in bulk.
So, if you’re tight on budget and need basic backup, go with wall-mounted. But if you’re investing for long-term solar storage, rack-mounted is a better value.
Where to Buy These Batteries?
Loom Solar is one of India’s fastest-growing solar and energy storage companies. Known for innovation and quality, Loom Solar offers both wall-mounted and rack-mounted lithium batteries, suited for homes, shops, and commercial establishments.
Their batteries are compact, come with advanced BMS safety features, and support high cycle life. Whether you are setting up a basic home solar system or a full hybrid solar + battery backup, Loom Solar has ready-to-install solutions with support and delivery across India.
They also provide expert guidance, so even if you’re new to solar energy, the installation and support team can help you choose the best battery setup for your energy needs.
Conclusion
Lithium batteries that are installed on the wall or on a rack are both excellent choices based on your requirements. If you want a compact, modern-looking solution for home, go for wall-mounted. If you need high capacity, long-term storage, choose rack-mounted.
Before buying, speak to an energy expert or installer. Ask about your current load, future needs, available space, and expansion plans. Remember, batteries are not just an expense — they are an investment in energy freedom and safety.
