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.
  • Modular stackable design scales by adding modules. Units stack to build a larger bank with no rewiring, growing from one module to a full backup system.
  • 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/RS232.
  • 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 up to 50A continuous 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 High-Voltage Storage: Pairs with high-voltage hybrid inverters to store solar and power essential home loads through outages.
  • Solar Self-Consumption: Stores excess daytime PV at 192Vdc and releases it in the evening to raise self-use of solar generation.
  • Small Commercial Storage: Supports offices and shops with a compact high-voltage tower that fits utility rooms without large floor space.
  • Off-Grid Power: Supplies independent high-voltage energy for cabins, kiosks, and remote sites away from the grid.
  • Backup Power: Keeps critical circuits running during grid outages as part of a daily-cycling storage system.
  • Scalable System Expansion: Acts as a modular building block in the TG-SS-5HVS series that grows by adding modules or towers.

Battery Safety & Protection

The SW-SS-5HVS2 is built around Lithium Iron Phosphate (LiFePO4) cells housed in an IP65-rated metal stand-stack enclosure, a chemistry chosen for thermal stability and a low risk of thermal runaway relative to other lithium types. The sealed metal case resists dust and water ingress, making it suitable for indoor and semi-sheltered utility installations.

For operational assurance, the pack communicates status over CAN, RS485, and RS232 with optional Bluetooth and WLAN monitoring so installers can track performance remotely. It is certified to UN38.3, MSDS, CE-EMC, IEC62619, and IEC63056 standards, confirming transport and safety compliance for the 192Vdc high-voltage design.

Performance & Lifecycle Advantage

Rated at 9.6kWh with a 192Vdc nominal output from 50Ah cells, the SW-SS-5HVS2 delivers stable high-voltage energy through 50A continuous charge and discharge within a safe window set by a 162Vdc discharge cut-off and 216Vdc charge cut-off. Its compact 680×185×1035mm stand-stack form factor makes efficient use of limited floor space.

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. With a metal enclosure and lower maintenance than lead-acid alternatives, it offers dependable long-term value for high-voltage residential and small commercial storage.

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 high-voltage inverter?

The SW-SS-5HVS2 operates at a 192Vdc nominal rating with CAN, RS485, and RS232 communication, so it pairs with standard high-voltage hybrid inverters. Confirm your inverter's voltage class and protocol during setup.

How much energy does it store and how long will it run my home?

It provides 9.6kWh of storage at 192Vdc. Runtime depends on your load—essential circuits such as lighting, routers, and refrigeration can run through an outage, while larger appliances draw it down faster.

Can I add more capacity later?

Yes. The TG-SS-5HVS series is modular, so you can stack additional modules or connect more towers to raise capacity as your needs grow.

Is it safe to install and use at home?

The LiFePO4 cells sit in an IP65-rated metal stand-stack enclosure, and the pack is certified to UN38.3, MSDS, IEC62619, and related safety standards. It is rated for 0°C to 50°C charging and down to −20°C discharging.
