Why zinc-bromide flow battery technology?

COMPETITIVE CAPEX
• 100% of the capacity is usable over the products lifetime, with no capacity fading, therefore no over-sizing required

BEST IN CLASS LCOS

• Warranted electrode stack lifetime: 36,500 kWh energy delivered or 10 years (whichever comes first)*

UNLIMITED SHELF LIFE

• Sustains regular outages without battery damage and can be suspended, stored or hibernated from 0% to 100%
state of charge

RECYCLE OR REPURPOSE

• For all Redflow battery components and electrolyte

CONSTANT POWER

• Charge 100% of the capacity with constant power, due to a flat voltage curve

*See full warranty document for details, T’s and C’s apply

GREATER SAFETY
• Fire retardant electrolyte, no thermal runaway due to separated tank and stack.
• No fire suppression system necessary or safety abuse testing required

NO ACTIVE COOLING REQUIRED
• Lifetime, safety and performance are not affected by temperature, even in the hottest outdoor locations

COMPACT AND HIGH ENERGY DENSITY
• 0.34m2 (3.7ft2) with expected energy throughput of 40MWh

INTUTIVE WEB BASED MANAGEMENT SYSTEM
• 24/7 remote self-monitoring with real-time data capture accessed via the web, through the MODBUS communications system

Check out Redflow’s Large Scale Battery (LSB) reference platform, designed and delivered by Redflow system integration partners for telecommunications, commercial, industry and grid-scale applications.

  • High energy density up to 600kWh for a single 20-foot container
  • Multiple containers can be interfaced for larger projects
  • Ideal for commercial and utility applications of 600–800Vdc.
