40.96kWh 448V Modular High Voltage Battery System With Eight Rack Modules

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.

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.

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.
