Why Solar Installers Choose This LiFePO4 Battery for Solar Battery Storage Projects

Key Features

Purpose-built for solar battery storage, every feature is optimized for fast installation, safe operation, and long service life.

Smart Battery Management System (BMS)

Built-in BMS monitors cell voltage, current, and temperature in real time. Multi-layer protection covers over-charge, over-discharge, over-current, and high/low temperature faults. The BMS communicates with inverters via CAN or RS485, enabling dynamic charge/discharge control for maximum efficiency.

Grade-A LiFePO4 Cells — Superior Safety & Longevity

The module uses prismatic Grade-A LiFePO4 cells with a proven ≥6,000 cycle life at 90% DOD — equivalent to over 16 years at one cycle per day. Lithium iron phosphate chemistry is inherently thermally stable, eliminating the thermal runaway risk associated with NMC chemistries.

Flexible Parallel Expansion

Up to 15 units can be connected in parallel via the RS485-2 daisy-chain port. Dial-switch addressing makes multi-unit commissioning fast and error-free — no laptop or configuration software required on-site.

Touch Screen & Status Indicators

The front panel features a color touch display plus three LED indicators (power, normal operation, alarm). Installers can switch communication protocols on-screen to match the connected inverter brand without rewiring.

How to Select the Right Protocol

Connect the host battery's CAN or RS485-1 port to the inverter's BMS communication port. Set the BMS host address to 1 via the front panel dial-switch. Slave batteries (addresses 2–15) are chained via RS485-2. Protocol selection (CAN vs. RS485) is configurable directly from the touch screen — no laptop needed.

Frequently Asked Questions About Our 51.2V LiFePO4 Lithium Battery

Everything solar installers and distributors need to know before specifying or stocking this product.

How many batteries can be connected in parallel?

Up to 15 units can be connected in parallel using the RS485-2 daisy-chain port, expanding total system capacity from 10.24kWh to a maximum of 153.6kWh. The host battery address is set to 1; slave units are addressed 2 through 15 via the front panel dial-switch.

Which inverter communication protocol should I use — CAN or RS485?

Both protocols are supported via the RS485-1/CAN combo port (RJ45). The preferred protocol depends on your inverter brand. For DEYE, CAN is recommended. Protocol selection is switchable directly on the battery's touch screen, so no rewiring is needed if you change inverter brands.

Is this battery IEC62619 certified?

Yes. The 51.2V 200Ah-HV model holds a valid IEC62619 safety certification issued by a third-party laboratory. CE, RoHS, MSDS, and UN38.3 (by sea) certificates are also included and available for download or provided with each shipment.

What is the expected cycle life of this LiFePO4 battery?

The battery is rated for ≥6,000 full charge-discharge cycles at 90% depth of discharge. Cycling once per day, this equates to over 16 years of service life — significantly longer than equivalent NMC-based battery systems.

Does this battery support OEM private label?

Yes. We are a factory-direct OEM battery manufacturer offering private label branding, firmware customization, co-branded documentation, and custom capacity configurations. Minimum order quantities start at 50 units. Contact our OEM team for a project quotation.

What is the warranty?

All units carry a 5-year manufacturer's warranty covering defects in materials, workmanship, and BMS firmware. Warranty claims are processed directly with our factory, with replacement units shipped on confirmed fault verification.
