51.2V 15kWh LiFePO4 Home Energy Storage Battery for Residential Solar Backup

The 51.2V Home Energy Storage Battery is designed for homeowners who want reliable backup power, higher solar self-consumption, and greater energy independence. Built with LiFePO4 battery technology, it delivers stable daily performance while supporting long-term residential energy management.

Unlike conventional backup generators, this battery system operates silently, requires no fuel, and automatically supplies electricity during grid outages. Whether installed in a single-family home, villa, vacation property, or small commercial building, it helps maintain power for essential household loads while reducing dependence on the utility grid.

Designed for Everyday Energy Management

A home battery should do more than provide emergency backup. This system stores excess solar energy during the day and automatically supplies stored electricity after sunset, allowing homeowners to maximize the value of their photovoltaic system.

Typical energy flow includes:

• Solar power supplies household loads first.

• Excess electricity charges the battery.

• Stored energy powers the home during the evening.

• Grid electricity is used only when necessary.

This intelligent charging and discharging strategy improves solar utilization while helping reduce electricity purchased during peak-rate periods.

Reliable Backup When the Grid Fails

Power interruptions can happen without warning. Integrated UPS functionality enables seamless switching between the utility grid and battery power, allowing critical household equipment to continue operating automatically.

Typical backup loads include:

• Refrigerators and freezers

• Internet routers and communication equipment

• Home security systems

• Medical devices

• Lighting

• Home office equipment

Because there is no engine, fuel tank, or exhaust system, the battery operates quietly and requires significantly less maintenance than traditional generators.

Flexible Installation for Different Homes

The compact enclosure supports both wall-mounted and floor-mounted installation, making it suitable for a variety of residential environments.

Applications include:

• Single-family homes

• Villas

• Holiday houses

• Rural residences

• Off-grid properties

• Small commercial buildings

Its IP67-rated enclosure provides protection against dust and water, allowing installation in both indoor and outdoor locations when installed according to local electrical requirements.

Smart Monitoring from Anywhere

The intelligent monitoring platform gives homeowners complete visibility into their energy system through a mobile application.

Users can monitor:

• Battery state of charge

• Solar generation

• Household electricity consumption

• Charging and discharging status

• System alarms

• Historical operating records

Remote access allows users to check system performance and adjust operating preferences even when away from home.

Engineered for Long-Term Performance

The battery uses high-quality LiFePO4 cells combined with an advanced Battery Management System (BMS) to monitor voltage, current, and temperature in real time.

Key benefits include:

• Stable daily cycling performance

• 100% Depth of Discharge (DoD)

• Up to 90% round-trip efficiency

• Maximum continuous discharge current of 200A

• Seamless UPS backup switching

• Low maintenance requirements

• 10-year limited warranty

The modular design also simplifies future system expansion as household energy demand grows.
