Vysokonapäťový batériový modul 2,56 kWh, 51,2 V — AI-HB_2.56LG-Unit G2 (HB051050A)

The High-voltage battery module 2.56 kWh, 51.2 V — AI-HB_2.56LG-Unit G2 is a modular energy storage unit engineered for residential and small commercial solar or backup systems. It provides 2.56 kWh of usable capacity at a nominal voltage of 51.2 V and is intended for installation as part of scalable battery banks. The design supports integration with compatible inverters and battery management systems (BMS) to enable safe high-voltage operation and coordinated charging and discharging.

Advantages

This battery module delivers a compact energy storage solution with an emphasis on modularity and safe high-voltage use. Its nominal 51.2 V architecture allows multiple units to be connected in series or parallel depending on system requirements, while the 2.56 kWh usable capacity per module simplifies capacity planning for peak shaving, backup power and load shifting. The unit is compatible with standard residential and small commercial inverter architectures and can be integrated into managed storage systems that employ an external BMS for state-of-charge monitoring and cell balancing.

Suitable for

• Residential solar energy storage systems
• Small commercial backup power installations
• Peak shaving and load-shifting applications
• Scalable battery banks in hybrid inverter systems

Key specifications

• Usable energy capacity: 2.56 kWh
• Nominal voltage: 51.2 V
• Form factor: modular rack/stackable unit suitable for multi-unit battery banks
• Intended environment: indoor utility and residential/commercial electrical installations
• Compatible integration: works with external inverters and BMS for charge/discharge control

How to use

Install the module in a ventilated, indoor environment following manufacturer and local electrical codes. Modules can be connected in series or parallel to achieve desired voltage and capacity; ensure that all modules in a bank are of the same type and state of health. Use a compatible inverter and an external or integrated BMS to manage charge/discharge cycles, cell balancing and protection functions. Follow recommended wiring practices, torque specifications for terminals, and safety procedures for high-voltage systems during installation and maintenance.

Recommendations

For reliable operation, operate the module within specified voltage and temperature ranges and incorporate a BMS for ongoing monitoring. Use the battery primarily for daily cycling applications such as peak shaving or solar self-consumption and reserve its capacity for emergency backup when needed. Schedule periodic inspections of electrical connections and the surrounding installation to ensure ventilation and thermal management are maintained.
