America, revolutionizing the way we harness and utilize energy. Designed with
innovation in mind, it seamlessly combines battery storage, solar power, and grid
connectivity to create a dynamic and sustainable power solution. With its intuitive
App control, homeowners have the power to optimize their energy usage, monitor
performance, and even contribute to a greener world. The EP800 also acts as a
reliable UPS, ensuring uninterrupted power supply during outages, while its
expandable capacity allows homeowners to adapt and grow their energy capabili-
ties as their needs evolve. Experience a new era of energy independence with the
EP800 – where efficiency, reliability, and eco-consciousness come together in
perfect harmony.

2.2 Working mode
The EP800 ESS offers four operating modes to accommodate various energy plans.
You can choose the one that best suits your home power supply configuration.
• Backup UPS
In this mode, the EP800 ESS acts as a reliable home backup power source that only
kicks in when the grid fails. It prioritizes charging its batteries from solar energy over
the grid, making it an eco-friendly and sustainable choice for your home energy
needs. With ample energy reserves, it provides a seamless power supply, perfect for
areas with unreliable grids.

• Scheduled Charge & Discharge
In this mode, you can customize the charge and discharge periods according to
your specific requirements. During the charge period, the EP800 ESS will draw
power from the grid, usually making use of off-peak tariff time windows (TOU) when
electricity rates are lower, to replenish its energy storage.
Moreover, you can set the battery State of Charge (SoC) limits to regulate the
amount of power that the EP800 ESS draws from the grid, allowing room in the
battery for a solar complement.
• Self Use (PV Priority UPS Mode)
In this mode, the EP800 ESS prioritizes the direct consumption of solar energy to
meet immediate household energy needs. Any surplus solar energy generated
during the day is intelligently stored in the battery for usage during peak hours or in
the event of a power outage. With such a strategy, the EP800 ESS ensures an
efficient and reliable power supply, reducing reliance on the grid and promoting
energy independence.
