  • Page 74 EP800, please feel free to contact BLUETTI support. Can I connect a 12kWp solar system to the EP800, even if it exceeds the PV input power? Will the EP800 automatically adjust the PV input current? Whether you can connect a 12kWp solar system to the EP800 depends on the voltage of your solar setup.
  • Page 75 Why doesn't the App show the load power? The App is designed to display the load power only when it exceeds 100W for each phase. If I set the SoC low value to 5%, will the EP800 shut down due to overnight Q15: self-discharge? No, the EP800 can automatically recharge from the grid and maintain a minimum SoC of 4% to ensure the system doesn't shut down.
  • Page 76 How can I share access to the EP800 with others? Q18: If you want to invite other BLUETTI App users to control the EP800, please follow the steps below: 1.Open the App and go to Settings.
  • Page 77 You can configure the Time of Use mode to fit your specific needs. During the charge period, the EP800 draws power from the grid, typically during off-peak tariff hours when electricity rates are lower, to replenish its energy storage and discharges during peak hours.
