The solution includes the inverter, ESS, optimizer, AC charger, meter, management system, and FusionSolar app. Multiple charging modes are available. The charger implements dynamic charging power based on the power information. This solution integrates energy storage (ESS) and EV charging into a “Storage—Charging—Grid/PV” ecosystem. It connects to both solar PV and the public grid, delivering reliable, cost-effective, and scalable power for diverse charging needs. Through intelligent energy coordination, it maximizes clean power usage, reduces electricity costs, and enhances grid reliability.
