40.96kWh 448V Modular High Voltage Battery System with Eight Rack Modules
This 40.96kWh modular high voltage battery system uses eight 51.2V 100Ah LiFePO4 modules to create a nominal 448V battery bank. It is designed for storage projects where capacity, rack footprint and high-voltage PCS integration must be balanced within one coordinated system.
Capacity-to-Footprint Planning
Increasing the number of series-connected modules raises the complete battery voltage and stored energy without increasing the system amp-hour rating. This allows a 40kWh-class battery bank to remain organized in a vertical rack architecture.
The module stack should be evaluated against the available cabinet height, service access and floor loading. The project should not be approved from electrical capacity alone.
Energy Density in the Rack
Eight modules provide a larger energy reserve while using a repeated mechanical format that simplifies cabinet planning.
Module-Level Handling
Individual modules can be transported and placed separately instead of moving the complete battery weight as one enclosure.
Service Access
The rack layout should preserve access to module connections, LCD information and the system output cable route.
Choosing a 40.96kWh Energy Reserve
A 40.96kWh high voltage battery system can be evaluated for larger solar self-consumption, scheduled energy use and backup-reserve projects.
The project calculation should identify normal daily energy movement, backup reserve and the maximum time available for recharging. Selecting a large battery without sufficient charging energy can prevent the system from restoring capacity between operating cycles.
The PCS determines AC power and conversion control, while the battery provides stored DC energy. Both values should be selected from the intended operating profile.
Structural and Logistics Requirements
The eight modules have a combined net weight of approximately 384kg. The battery rack, fixing method and supporting floor should be evaluated for the complete installed weight.
Each module is 440 × 480 × 150mm. Space is also required for interconnection cables, DC protection, output connections and safe inspection access.
The eight individual shipping cartons have a combined gross weight of approximately 432kg before pallets and external packing are included.
The IP20 battery modules require a controlled indoor technical environment with no condensation and restricted access.

40.96kWh High Voltage Battery FAQ
Does the system occupy the same space as one battery module?
No. The rack must accommodate eight modules plus cables, protection equipment and service clearance.
Can the eight modules be split between two PCS units?
The product is specified as one coordinated series battery bank. A different topology requires a separate system design.
Is 40.96kWh the guaranteed usable capacity?
It is the nominal DC energy. Usable AC energy depends on PCS efficiency and system settings.
Can the battery room have condensation?
No. The documented humidity range requires non-condensing conditions.
What structural information should be checked?
Check the rack load rating, floor capacity, fixing method, access route and module service clearance.
