48V / 51.2V Floor-Standing LiFePO4 Battery — 300Ah and 400Ah

Models: FT-48300 · FT-48400

The highest usable capacity per enclosure in the home range, on castors so a two-person crew can position and service it without lifting gear. Specified for larger homes, villas and small commercial backup where a wall mount would need several units to reach the same storage.

Buyer decision points

What project teams should confirm before ordering

This page is structured around technical review, procurement qualification and project conversion rather than retail pricing.

  1. 01

    Confirm the model, not just the series

    This page covers a whole capacity range. Quote against a single model code so the terminal, enclosure and current rating on your purchase order match what ships.

  2. 02

    Charge window and cold climates

    Charging must not start below 0 °C; the BMS blocks it to protect the cells. Discharge continues to -20 °C. For cold markets, ask about the self-heating option before you specify.

    Recommended · continuous maximum 200 A

  3. 03

    Inverter protocol review

    Provide the exact inverter brand and model. CAN or RS485 protocol, cable pinout and firmware version should be verified on the bench before sample approval.

    Up to in parallel

  4. 04

    Series and parallel limits

    Review total current, busbar and cable sizing, protection coordination, address settings and topology for the specific project.

    Protection rating: IP20

  5. 05

    Installation environment

    This range is rated IP20. Match that to where the battery actually sits — an indoor rating on an outdoor install voids the warranty and creates a safety risk.

  6. 06

    Documentation scope

    Confirm which pack-level and cell-level certificates apply to the exact production configuration and target market before publishing or purchasing.

Application fit

Where this series is specified

Positioned for distributors, system integrators, installers and OEM brands specifying batteries into their own systems.

01

Larger homes and villas

One enclosure instead of two or three wall units, which shortens install time and reduces DC cabling.

02

Small commercial backup

Shops, clinics, offices and farms where outage protection is the project driver.

03

Off-grid properties

Remote sites where stored PV has to carry the whole evening and night load.

04

Distributor and OEM programmes

Branded enclosure, protocol configuration and export documentation.

OEM / ODM capability

Buyer questions

Technical and purchasing FAQ

Which model should I quote?

Start from the load, not the capacity. Send the continuous and peak current, the daily energy requirement and the autonomy you need, and our engineers will map that onto a model code before quotation.

Will it communicate with my inverter?

RS485 and CAN interfaces are provided, but compatibility should not be assumed from the brand name alone. Send the exact inverter model, its protocol document and the cable pin definition so we can review it and bench test the pairing.

Is this suitable for outdoor installation?

No. The protection rating listed in the specification table is intended for protected indoor environments. Keep the enclosure upright, lock the castors and allow clearance for service access and heat dissipation.

Are the optional functions standard?

No. Bluetooth, display, communication modules and low-temperature charge protection are options. Confirm what you need during quotation so the BMS, enclosure, wiring and documentation are configured accordingly. This model is rated IP20.

What information is required for an OEM quotation?

Model code, quantity, target market, current requirement, optional functions, logo or label files, documentation scope, target delivery time and application details.

What does the warranty cover?

The warranty term is stated in the commercial section of the specification table. Warranty handling, spare-part supply and RMA turnaround are agreed per distribution or OEM contract, and depend on the installation staying within the stated temperature and current limits. For this model: 5 years / 6,000 cycles, to 70 % capacity retention.
