On the Cook Island of Aitutaki, a 20-foot battery container has been controlling the microgrid there since 2019, storing energy from various sources and making it available in order to achieve the highest possible efficiency, grid stability and CO2 savings.
The Cook Islands project tackles this by integrating battery storage systems with existing solar farms, ensuring 24/7 clean energy access. Led by local utilities and international partners, the pilot uses lithium-ion batteries with a capacity of 6 MWh.
It integrates high-quality IP65-rated stainless steel switchgear and 3-phase electric switchboards to offer reliable power management for island solar setups. The corrosion-resistant stainless steel build ensures durability and longevity, even in the most challenging coastal.
Combines high-voltage lithium battery packs, BMS, fire protection, power distribution, and cooling into a single, modular outdoor cabinet. Uses LiFePO₄ batteries with high thermal stability, extensive cycle life (up to 6000 cycles), and stable performance under load.
The innovative and mobile solar container contains 196 PV modules with a maximum nominal power rating of 130kWp, and can be extended with suitable energy storage systems.
