BACK-UP Mode
NOTICE
•
In BACK-UP mode, you can set different battery SOC values for grid-tied and off-grid status.
When the power grid is cut off, the inverter switches to off-grid mode, and the battery can dis
-
charge to supply power to the load to ensure that the BACK-UP load does not lose power; When
the power grid is restored, the inverter switches to grid-tied mode. If the battery’s SOC is lower
than the set SOC, the battery can be charged by power grid.
• The purchase of electricity from the power grid to charge the battery must comply with local laws
and regulations.
• Recommended for use in areas with unstable power grid.
• When the SOC of the battery is lower than the set value, use PV power generation and electricity
from the power grid to supply load and charge the battery.
•
When the power grid is cut off, if the PV power generation cannot meet the load usage, the battery
discharges to supplement this part of power to ensure that the load connected to BACK-UP port
does not lose power.
