HVB-5K and HVB-10K
Stackable High-Voltage Batteries
Modular high-voltage LiFePO4 battery towers for residential and small-commercial storage, using 5.12 kWh or 10.24 kWh series modules.
Product overview
Built around the application.
Home energy storage systems allow excess renewable energy to be stored for periods of higher demand or when generation is unavailable. This can reduce grid dependence and increase household energy autonomy when the battery, inverter, protection design and load profile are engineered as one system.
The stackable HVB platform packages high-voltage battery modules into expandable towers for residential and small-commercial storage. HVB-5K uses 5.12 kWh modules and HVB-10K uses 10.24 kWh modules. Final configuration must follow the selected inverter voltage window, power requirement, communication protocol, installation environment and applicable local standards.
Two stackable module platforms
Select 5.12 kWh HVB-5K modules or 10.24 kWh HVB-10K modules, then engineer the tower around the inverter voltage window and required energy.
Multi-cluster expansion
Supports up to 12 clusters in parallel, scaling to 552 kWh with HVB-5K modules or 983 kWh with HVB-10K modules. Final sizing requires system engineering.
Installation-focused architecture
Zero-wiring, plug-and-play stacking and one-person installation simplify on-site deployment. Electrical work, commissioning and code compliance still require qualified project execution.
Integrated battery management
RS485/CAN communication, optional LED/Wi-Fi state-of-charge monitoring, real-time monitoring, remote control and OTA updates support system visibility.
IP54 enclosure protection
The IP54-rated enclosure supports installation in suitable indoor and protected outdoor environments. Final placement must follow site conditions and applicable installation requirements.
Defined operating envelope
The operating envelope covers charging from 0°C to 45°C, discharging from -20°C to 60°C and at least 5,000 cycles.
