Mid-sized Batteries + Inverter systems
250 kWh - 1 MWh
These cabinet based systems are best for developers and EPCs building medium-large scale commercial and industrial renewable energy projects such as hospitals, schools, factories, hotels, and warehouses using 480 volts as well as distribution-level grid projects. Systems can be combined to achieve larger scale and their smaller form factor allow for greater flexibility, ease of logistics and simpler permitting.
