Solar Powered Level 3 EV Charging

The Oasis system by Harnyss is not just a product but an engineered solution tailored to enhance the EV charging infrastructure. It is reflective of our commitment to developing energy storage systems that are not only reliable but also align with the principles of sustainability and economic viability in the transportation sector.


System Integration and Power Supply Management

The Harnyss Oasis system is configured to dovetail with the expansion of EV charging infrastructure. It supports a continuous power supply, essential for rapid EV charging. This is particularly relevant for facilities that capitalize on lower off-peak electricity tariffs to charge the storage system, thereby reducing operational costs during peak demand. Such a feature is indispensable for high-traffic charging locations where uptime is critical.


Design and Deployment Versatility

The Oasis system's modular design facilitates deployment across varied environments—from dense urban to remote areas—ensuring adaptability to the evolving demands of EV charging infrastructure. It supports the establishment of a robust and flexible charging network, capable of scaling with the projected growth in the EV market.


Implications for EVSE Landscape

As the Electric Vehicle Supply Equipment (EVSE) sector progresses, the role of sophisticated energy storage solutions becomes increasingly pronounced. The Harnyss Oasis system aligns with the industry's trajectory towards more effective and extensive charging networks. It offers Charge Point Operators (CPOs), installers, and hardware suppliers a scalable, modular solution that underscores operational efficiency and economic feasibility.
