Why Choose Our 5.12kWh Wall-Mounted Battery?

1. Premium EVE LiFePO4 Cells – Quality at the Core

The performance of an energy storage system starts with the quality of its cells.

Our 5.12kWh battery uses 16 EVE LF100LA prismatic LiFePO4 cells connected in a 16S1P configuration, providing a nominal voltage of 51.2V and a rated system capacity of 100Ah.

According to EVE's official technical specification, each LF100LA cell has a rated capacity of 102Ah under specified laboratory testing conditions.

Why EVE LF100LA Cells?

• Established Battery Manufacturer: EVE is a recognized lithium battery manufacturer supplying cells for energy storage and industrial applications.

• Long Cycle Life: Rated for 5,000 cycles at 25°C under 0.5C charge/discharge testing, with at least 80% capacity retention.

• LiFePO4 Chemistry: Offers good thermal stability and long-term suitability for stationary energy storage applications.

• Low Internal Resistance: Designed to support efficient charge and discharge performance.

• Reliable Energy Storage: Suitable for applications requiring regular daily charging and discharging.

With carefully selected components and proven lithium iron phosphate technology, this battery is designed to provide dependable energy storage over years of operation.

Cycle-life figures refer to the EVE LF100LA cell under manufacturer-defined testing conditions. Actual battery system performance depends on operating conditions and system configuration.

2. JK V19 Smart BMS – Intelligent Protection and Battery Management

A high-quality battery deserves a capable management system.

Our wall-mounted battery is equipped with the JK V19-PB2A16S10P Smart BMS, rated for 100A charging and discharging.

The BMS monitors battery operating conditions, manages protection functions, and helps keep the system operating within its configured safety limits.

Key BMS Features

• 100A Maximum Charging Current: Supports high-current charging when operating conditions permit.

• 100A Maximum Discharging Current: Provides substantial power delivery for compatible residential inverter systems.

• 2A Active Cell Balancing: Helps reduce voltage differences between individual cells during battery operation.

• Battery Monitoring: Supports Bluetooth communication for access to battery information.

• Inverter Communication: CAN and RS485 interfaces support communication with compatible inverter systems.

• Configurable Battery Management: Helps optimize battery operation according to the system's electrical requirements.

Why Does 2A Active Balancing Matter?

Even high-quality battery cells can develop small voltage differences after repeated charging and discharging cycles.

The JK active balancing system transfers energy between cells to help reduce these differences, rather than simply dissipating excess energy through passive resistors.

By maintaining better voltage consistency across the 16-cell battery pack, active balancing can help prevent individual cells from reaching protection thresholds prematurely.

The result is more consistent battery operation and improved utilization of the available capacity.

3. 5.12kWh Energy Storage – Make Better Use of Your Solar Power

Generating electricity is only part of a successful solar installation. Storing that energy allows you to use more of it when you actually need it.

With a nominal capacity of 5.12kWh (51.2V × 100Ah), this battery provides practical energy storage for everyday residential applications.

Solar Self-Consumption

Store surplus solar electricity during daylight hours and use it in the evening instead of relying entirely on the grid.

Home Backup Applications

When paired with a properly configured backup-capable inverter, stored battery energy can help supply selected household loads during grid outages.

Off-Grid Living

Combine the battery with a suitable off-grid inverter and solar charging system to support independent electricity use in cabins, small homes, and remote installations.

Daily Energy Management

Store electricity during lower-cost periods and discharge during higher-cost periods where your inverter and local electricity tariff support this functionality.

Actual usable capacity and backup duration depend on battery settings, inverter efficiency, connected loads, operating temperature, and state of charge.

4. Wide Inverter Compatibility – Flexible System Integration

Our 51.2V LiFePO4 battery is designed for integration with compatible 48V-class low-voltage solar inverters.

The JK V19 BMS platform supports mainstream communication interfaces, including CAN and RS485, with selectable inverter communication protocols.

Depending on the specific inverter model and communication settings, potential integration options include systems from:

Deye | Growatt | GoodWe | SRNE | SOFAR | SMA

PYLON communication protocol options may also be available for compatible inverter configurations.

Important: Compatibility must be confirmed by exact inverter model, firmware version, wiring, and BMS protocol settings. A supported communication interface does not automatically guarantee compatibility with every inverter from a listed brand.

Not sure whether your inverter is compatible?

Contact our technical team with your inverter brand and model number before ordering. We'll help you check the appropriate battery connection and communication configuration.

5. Space-Saving Wall-Mounted Design

Powerful energy storage doesn't need to take up valuable floor space.

This 5.12kWh battery features a clean, minimalist wall-mounted enclosure designed to complement modern residential solar installations.

Designed for Practical Home Installation

• Compact wall-mounted format to help save floor space.

• Clean white exterior for a modern, understated appearance.

• Integrated battery enclosure housing the cells and BMS.

• Suitable for properly designed residential energy storage installations.

The complete battery weighs approximately 47.5kg. Installation requires a load-bearing mounting surface and appropriately rated fixing hardware.

Professional installation is recommended. Installation environments must meet the product's applicable protection and temperature requirements.

6. Built for Long-Term Energy Storage

A home battery is a long-term investment, and durability matters just as much as initial capacity.

The EVE LF100LA cells are specified for 5,000 charge-discharge cycles with at least 80% remaining capacity under controlled 25°C, 0.5C/0.5C testing conditions.

For homeowners, this provides a meaningful technical benchmark when evaluating battery longevity.

Combined with JK active balancing, configurable battery protection, and LiFePO4 cell chemistry, the battery is designed for repeated daily energy storage use.
