Durable performance with over 6,000 cycles
BESS RS R51100 is developed according to the synchronous system from Cell – BMS – Pack researched and produced by Topband itself. This synchronization helps the battery operate optimally throughout its life cycle, minimizing risks and promoting high performance in real conditions. With more than 6,000 cycles of use, users can rest assured that the system will operate stably for 15 – 20 years, bringing long-term economic value and optimizing investment costs.
Compact, flexible and easy to install design
The compact, modern 3U design makes the RS R51100 easy to install in any home space, from technical systems to utility rooms. With a variety of designs, the product can be installed in many ways such as floor-standing, wall-mounted, cabinet-mounted, shelf-mounted or stacked. Thanks to that, whether it is an apartment, townhouse or villa, users can deploy it neatly and aesthetically, and easily expand if the need increases in the future.

Capacity expansion up to 160 kWh
Flexible expansion is a big strength of BESS RS R51100. With support for connecting up to 32 modules in parallel, the system can be expanded from 5 kWh to 160 kWh, suitable for all scales of use from small apartments to multi-storey houses or small-scale businesses. Simple expansion helps users not have to invest heavily at the beginning but can gradually upgrade when electricity consumption increases.

Compatible with many inverters
The RS R51100 is compatible with most popular inverters on the market today. This makes it easy to connect the system to existing or newly installed solar configurations, while shortening deployment time, ensuring synchronous performance and stable operation over a long period of time.
Smart management with T-Smart Cloud platform
The most outstanding difference of the BESS RS R51100 system is the ability to manage intelligently through the T-Smart Cloud platform. Users can monitor operating history, cell status, charge-discharge status, temperature, warnings and energy graphs right on their phones or computers. The ability to automatically balance cells helps the battery operate evenly, increase its lifespan, and also allows remote firmware upgrades without the need for a technician to come to the site. This is a feature that only appears on high-end BESS lines, bringing absolute convenience and peace of mind to the family.
