EV-SB power button
When ON, the EVERVOLT Home Battery System can intelligently switch
between on-grid and off-grid without human intervention.
When OFF, manual control of the EV-SB will be enabled when the
internal relay is not switched automatically. When some unrecoverable
failure is encountered, causing the system to stop running and the home
load to lose power, the following operations can be performed:
1. Open the door of the EV-SB.
2. Turn off the breaker between the inverter and the EV-SB, as well as
the breaker between the EV-SB and the generator.
3. Turn off the main breaker on the grid side.
4. Wait for 60s.
5. Press the EV-SB power button to enter manual maintenance mode.
6. Use the tool to turn the left and right relays to ON.
7. Turn on the main breaker to make the grid ready to power the home
load!
8. Turn on the breaker between the inverter and the EV-SB to make the
inverter run again.
9. Close the door of the EV-SB.
