Features

  • LiFePO4 chemistry delivers safe, long-lasting power. The cobalt-free cells resist thermal runaway and hold capacity through deep daily cycling, rated for 6000+ cycles at high state of health.
  • Wall-mounted design saves floor space. The slim cabinet mounts on a garage or utility-room wall, keeping the 5.12kWh pack out of the way yet easy to cable and inspect.
  • A multi-protocol BMS guards every cell. It tracks per-cell voltage, current and temperature, balances cells and blocks over-charge, over-discharge, over-current and short circuit, talking to inverters over CAN/RS485.
  • Long service life cuts ownership cost. Rated for 6000+ cycles, it supports years of daily charge and discharge without premature replacement.
  • Wide operating range suits tough sites. It discharges from -20°C to 50°C and handles current, staying stable in unconditioned indoor and sheltered spaces.
  • Parallel-ready design grows with you. Add more units on the same bus to expand capacity while keeping the existing inverter and cabling.

Applications

  • Residential Backup: Runs lighting, refrigeration, and everyday appliances through outages as part of a home storage system.
  • Solar Energy Storage: Stores daytime PV in a 5.12kWh bank for evening and nighttime use.
  • Off-Grid Power: Supplies independent power for cabins and small remote sites.
  • Daily Household Loads: Covers typical 25.6V home energy needs with longer runtime than entry units.
  • Garage and Utility Room: Wall-mounted format saves floor space in tight indoor areas.
  • Small Commercial: Powers essential equipment at markets or job sites without grid access.

Battery Safety & Protection

The SW-24200-W is built around Lithium Iron Phosphate (LiFePO4) cells, a chemistry valued for thermal stability and a low risk of thermal runaway compared with other lithium types. The cells sit inside a metal enclosure rated IP20, which protects against solid-object contact and limits dust ingress in indoor and sheltered installations.

An integrated battery management system, linked through the unit's CAN, RS485, and RS232 ports, handles cell monitoring and balancing for the 8S2P stack. Optional Bluetooth and WLAN modules let installers check status remotely, while the wide operating envelope—0°C to 50°C charging and −20°C to 50°C discharging—keeps the pack online through seasonal swings. UN38.3, MSDS, and CE-EMC certifications confirm international transport-safety and electromagnetic-compatibility compliance.

Performance & Lifecycle Advantage

Rated at 5.12kWh (200Ah) with a 25.6V nominal output, the SW-24200-W delivers stable energy for daily household loads through its 100A continuous charge and discharge rating. A discharge cut-off of 21.6Vdc and charge cut-off of 28.8Vdc define a safe operating window that protects cell health over time.

The LiFePO4 chemistry provides a long design life of 6000 cycles at 70% capacity retention under 25±2°C, 0.5C conditions, supporting years of daily cycling. Weighing 54kg net with a compact 580×390×195mm form factor, the unit suits space-limited homes, and against lead-acid it offers lighter weight, lower maintenance, and better tolerance for frequent deep cycling—lower lifetime cost for backup and off-grid use.

Warranty

LiFePO4 batteries are backed by a 5-year warranty. If you experience any quality issues within the warranty period, please contact us and we will arrange a replacement or repair promptly.

Frequently Asked Questions

Will this battery work with my 25.6V inverter?

Yes, it runs at 25.6V nominal with CAN, RS485, and RS232 communication, connecting to most standard 25.6V off-grid and hybrid inverters. Confirm your inverter's protocol during setup.

How long can it power my home?

With 5.12kWh (200Ah) stored, a 500W household load runs roughly 9–10 hours, while heavier appliances draw it down faster. The 100A rating handles typical startup currents.

Can I add more capacity later?

Yes. Multiple units can be paralleled over the RS485/CAN bus to expand storage as your needs grow, scaling from one pack to a larger bank.

Is it safe for indoor use?

The LiFePO4 cells and metal IP20 enclosure keep operation stable, charging at 0–50°C and discharging to −20°C. UN38.3, MSDS, and CE-EMC certifications confirm safety and compliance.
