Why zinc-bromide flow battery technology?

COMPETIVE 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

ZBM2 Technical Specifications

VOLTAGE
+ 48 Volt DC nominal batteries (typical operating range 40-60V)

CAPACITY
+ Maximum 10kWh energy output per daily cycle
+ No reserved battery capacity requirement – full 10kWh cycle depth available

DIMENSIONS
+ 845 L x 823 H x 400 W (mm)
+ 33 L x 32 H x 16 W (in)

SAFETY DATA SHEET
+ DG Class 8 for electrolyte 

POWER RATING
+ 3kW (5kW peak)
+ 3kW continuous: current up to 75A (40V disconnection point) *1
+ 5kW duration depending on the State of Charge (SOC): current up to 125A (40V disconnection point) *1, 2

REGULATORY COMPLIANCE MARKS
+ CE and RCM

WARRANTY
+ Electrode stack: 36, 500 kWh of energy delivered or 10 years (whichever comes first) *3
+ All other parts: 3 years *3

Expected electrode stack throughput 40,000 kWh
+ No cycle depth limitations – battery performance and lifetime is not sensitive to cycle depth
