An ark powered by Copenhagen's surprisingly decent sunshine (yes, really!) and a revolutionary Community-BESS container. Let's break down this lifesaver: Despite its latitude, Copenhagen receives 1,700+ annual sun hours (Danish Meteorological Institute), enough to make solar viable.
It means the price for a BESS DC container – comprising lithium iron phosphate (LFP) cells, 3. 7MWh and 4-hour duration, delivered with duties paid from China to the US – will have nearly halved by the end of 2024 compared to the highs of 2022, when it hit US$270/kWh.
Built-in solar panels provide power to maintain charge for batteries. Includes hold-down straps, lid with. Built-in BMS protects your battery and optimizes charging from solar .
All-in-one containerized design complete with LFP battery, bi-directional PCS, isolation transformer, fire suppression, air conditioner and BMS; Modular designs can be stacked and combined.
