Floor-standing energy storage battery · B2B project supply
48V 300Ah Floor-Standing LiFePO4 Battery — 15.36kWh
The FT-48/51.2V300Ah is a 51.2V nominal 300Ah floor-standing LiFePO4 battery holding 15.36kWh per cabinet — roughly 13.8kWh usable at the 90% DOD design point. It discharges to 200A, about 10.24kW on the battery side, so it pairs with 48V hybrid inverters up to the 10kW class. CAN, RS485 and RS232 are all fitted, and up to 15 cabinets parallel into a 230kWh bank for residential solar, small commercial backup and off-grid projects.

Buyer decision points
What project teams should confirm before ordering
These are the six questions our engineering team works through before issuing a quotation. Settling them early shortens the sampling cycle and prevents protocol or current mismatches after delivery.
Current and system design
Recommended current is 100A and maximum current is listed as 200A. Confirm actual continuous-current configuration against the final BMS.
Parallel expansion
Up to 15 units in parallel is stated in the supplied specification. Review total current, busbar, protection and communication design for the project.
Installation environment
IP20 is intended for protected indoor installations. Keep the enclosure upright, lock the wheels and provide installation and heat-dissipation clearance.
Optional enhancements
Touch LCD, self-heating, app, Bluetooth telemetry and active fire-extinguishing modules are optional and must be selected before quotation.
Documentation scope
Confirm which pack and cell certificates apply to the exact production configuration and target market before publishing or purchasing.

Buyer questions
Technical and purchasing FAQ
Answers should help procurement teams evaluate fit, quotation requirements and customization scope.
Can this battery communicate with my inverter?
CAN and RS485 interfaces are listed, but compatibility should not be assumed from the brand name alone. Send the exact inverter model, protocol document and cable pin definition for review and bench testing.
Can multiple FT-48/51.2V300Ah batteries be connected in parallel?
The supplied specification states up to 15 parallel units. The actual project must review inverter limits, total current, protection, busbar or cable design, address settings and communication topology.
Are Bluetooth, app monitoring, self-heating and fire extinguishing standard?
No. These functions are listed as optional enhancements. Confirm required options during quotation so the BMS, enclosure, wiring and documentation can be configured accordingly.
Is this battery suitable for outdoor installation?
The supplied protection rating is IP20, so it should be installed in a protected indoor environment or suitable enclosure. Do not position it where it is exposed to rain, condensation, corrosive atmosphere or uncontrolled heat.
What information is required for an OEM quotation?
Please provide quantity, target market, inverter brand and model, current requirements, parallel quantity, optional functions, logo or label files, documentation scope, target delivery time and application details.
