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 9.6kWh 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 whole-home essential loads through extended outages.
  • Solar Energy Storage: Stores 9.6kWh of daytime PV for evening and overnight use.
  • Off-Grid Power: Supplies independent power for larger cabins and remote sites.
  • 48V System Upgrade: Fits higher-voltage bus installations needing reduced current.
  • Garage and Utility Room: Wall-mounted format mounts on a reinforced wall without floor space.
  • Small Commercial: Backs up essential equipment at sites without reliable grid.

Battery Safety & Protection

The SW-48200-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 15S2P 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, CE-EMC, IEC62619, and UL1973 certifications confirm international transport-safety and broader compliance.

Performance & Lifecycle Advantage

Rated at 9.6kWh (200Ah) with a 48V nominal output, the SW-48200-W delivers stable energy for larger loads through its 100A continuous charge and discharge rating. A discharge cut-off of 40.5Vdc and charge cut-off of 54Vdc 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 85kg net with a 690×485×226mm form factor, the unit suits reinforced wall mounting, 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 work with my 48V inverter?

Yes, it runs at 48V nominal with CAN, RS485, and RS232, connecting to most standard 48V off-grid and hybrid inverters. Confirm your inverter's protocol during setup.

How long can it power my home?

With 9.6kWh (200Ah) stored, a 800W load runs roughly 10–12 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 scale storage as your system grows.

Is it certified for safety?

The LiFePO4 cells and metal IP20 enclosure keep operation stable, charging at 0–50°C and discharging to −20°C. It carries UN38.3, MSDS, CE-EMC, IEC62619, and UL1973 certifications.
