ESS510 Energy Storage System
5.5KW Solar Inverter paired with a 5KWH Lithium-ion Battery
The ESS510 Energy Storage System is a comprehensive solution that combines an inverter and a battery into a single unit. It provides an affordable and self-sufficient way for homeowners to store surplus solar energy during the day, enabling them to power their homes both day and night. Key features include a lightweight, easily expandable Lithium-ion battery module that is lighter than traditional lead-acid batteries, along with a compact and stylish design. Additionally, the ESS510 offers three operating modes with nine intelligent settings to customize energy management for individual homes. Users can easily switch between modes based on their specific needs, including options for prioritizing PV power supply, charging sources, load supply sources, and scheduling power usage or charging times according to peak and off-peak hours.
