Watts Battery offers a portable and Lego-like all-in-one energy storage solution that can simplify electrification and access to renewable energy. Watts Battery modules allow the users to become energy self-sufficient, reduce electricity bills and carbon emissions while enabling them to scale up their system with a DIY approach. Unlike other solutions, our product does not require any fixed mounting, is scalable, and highly portable, allowing the owner to move and use them anywhere (at home, at work, at camping). Crucially, they do not require any other components or devices and can directly connect to solar panels or any other generation source, making it an ideal product for remote and rural areas. Watts Battery also offers unique cloud-based demand response capabilities that leverage behind-the-meter data collected through online connected modules, giving utility companies a unique opportunity to effectively and more efficiently plan their networks and save on capital investments.
