Applications
CONTAINER STORAGE
- Lowest cost of ownership than traditional energy storage solutions
- High Expected lifetime up to ≥30 years
- High Efficiency & Depth of Discharge
- Maintenance Free
- Attractive price and long asset lifetime
- Anti-theft mechanism to safeguard assets
SOLAR & RENEWABLES
- Plug-and-play replacement of Lead Acid or Li Ion batteries
- Compatible with existing inverters
- Safe with no risk of thermal runaway
- Wide operating temperature range minimizes (and even eliminates) auxiliary cooling (or heating) infrastructure (and therefore cost)
- High delivered efficiency results in low opex so faster payback
- Long cycle life
- Can be charged quickly to optimize PV solar sizing
TELECOM Cell TOWERS
- Compatible with existing rectifier or DC electronics infrastructure
- Wide operating temperature range minimizes auxiliary cooling infrastructure.
- High cycle life + high efficiency + low auxiliary opex = lowest cost of ownership and shortest payback
- At off-grid locations, rapid charge capability reduces generator runtime and increases generator efficiency.
- Plug-and-play replacement for Lead Acid or Li Ion batteries
