Moonwatt showcases sodium-ion storage solutions for utility-scale applications
Moonwatt unveiled a modular sodium-ion battery storage system for utility-scale PV plants at The Smarter E trade show in Munich, designed as distributed units placed across solar arrays instead of containerised blocks. The system uses passively cooled NFPP sodium-ion cells in DC- or AC-coupled configurations, targeting 93–94% solar-to-grid efficiency, lower balance-of-plant costs, and highly scalable, low-maintenance deployment without lithium, cobalt, or active cooling.
