Hanchu HOME-ESS-LV-9.4K 9.4kWh 51.2V LiFePO₄ Lithium Battery

The Hanchu HOME-ESS-LV-9.4K is an advanced 9.4kWh low-voltage lithium battery designed for residential solar, backup-power and energy-storage applications. Combining high-capacity LiFePO₄ blade-cell technology with intelligent energy management and integrated safety protection, it provides reliable stored energy for homes, farms, offices and small businesses.

With a nominal voltage of 51.2V, the battery is suitable for compatible low-voltage solar inverters. Its 95% depth of discharge provides approximately 8.93kWh of usable energy, allowing customers to make effective use of the available storage capacity while maintaining safe battery operation.

Advanced LiFePO₄ blade-cell technology

The HOME-ESS-LV-9.4K uses lithium iron phosphate blade cells selected for their excellent thermal stability, safety and long service life. The blade-cell and cell-to-pack design improves energy density while maintaining a slim and practical enclosure.

LiFePO₄ chemistry is considerably safer and more stable than many conventional lithium battery chemistries, making it particularly suitable for residential and commercial energy-storage installations.

Intelligent Battery Management System

The integrated smart Battery Management System continuously monitors the battery’s voltage, current, temperature and operating condition. It manages charging and discharging to improve battery performance, protect the cells and extend the system’s operating life.

Protection functions include:

• Overvoltage protection

• Overcurrent protection

• Overtemperature protection

• Cell-voltage monitoring

• Abnormal pressure protection

• Charge and discharge management

• Battery status and fault monitoring

High usable capacity

The battery provides 9.4kWh of nominal storage capacity and supports a depth of discharge of up to 95%. This delivers approximately 8.93kWh of usable energy under suitable operating conditions.

Its 100A nominal charge and discharge current supports strong backup performance and efficient energy transfer when used with a compatible inverter.

Expandable energy storage

The modular design allows up to 16 HOME-ESS-LV-9.4K batteries to be connected in parallel. Customers can start with one battery and expand their storage system as their electricity requirements grow.

Expandable storage options include:

• 1 battery: 9.4kWh

• 2 batteries: 18.8kWh

• 3 batteries: 28.2kWh

• 4 batteries: 37.6kWh

• Maximum 16 batteries: 150.4kWh

Final system design and parallel configuration must be confirmed according to the selected inverter’s battery-voltage, current and communication requirements.

Multiple communication options

The HOME-ESS-LV-9.4K supports CAN, RS485, Wi-Fi and Bluetooth communication. This allows integration with compatible inverters and monitoring platforms for improved system visibility and energy management.

Through Hanchu’s intelligent platform, supported installations can provide access to operating information, remote monitoring, historical system data and over-the-air software updates.

Integrated safety features

Safety is reinforced through several built-in protection systems. The battery incorporates thermal-aerosol fire suppression, a rear-mounted pressure-relief valve, intelligent BMS protection and an external circuit breaker.

The heat-dissipation backplate helps manage operating temperature and improves system stability during charging and discharging.

Flexible installation

The battery’s concealed mounting bracket supports both wall-mounted and floor-standing installation. Its slim design helps save installation space while maintaining a clean, professional appearance.

Dual rear wiring connections simplify parallel installations and allow multiple batteries to be positioned neatly alongside one another.

IP65 enclosure protection

The IP65-rated enclosure offers protection against dust and water ingress, making the battery suitable for a variety of indoor and protected outdoor installations.

The installation location must still comply with the manufacturer’s requirements and applicable electrical regulations. The battery should not be installed where it may be submerged, physically damaged or exposed to unsuitable environmental conditions.

Typical applications

The Hanchu HOME-ESS-LV-9.4K is suitable for:

• Residential solar-energy storage

• Load-shedding backup

• Self-consumption of solar energy

• Home backup-power systems

• Farms and smallholdings

• Offices and small businesses

• Off-grid and hybrid solar installations

• Expanding an existing compatible Hanchu battery bank
