  There are three power sources in On-grid with backup mode, PV power, battery power, and utility power.
  Charging mode: Only PV power exists to charge the battery. There will be power flow animation from solar modules to the battery Line mode: Utility power exists or is available during this mode. All possible power flows are described below.

1. If PV power and battery energy are not available, the utility will provide power to loads directly. There will be a power flow animation from the solar module icon to the loading icon.

2. If only utility power exists, it will charge the battery and provide power to the load. There will be power flow animation from utility icons to battery and load icons.

3. If only PV power exists without a battery connected, it will provide power to the load. If there is remaining power, it will feed into the grid. There will be power flow animation from the PV module icon to the load icon and to the utility icon.

4. If PV power is sufficient but battery power is insufficient, PV power will charge the battery, provide power to the load, and feed into the grid.
   There will be power flow animation from PV module icon to battery, to load icon, and to utility icon.

5. If PV power is weak, utility exists and battery power is insufficient, PV power and utility power will charge the battery at the same time. Besides, utility power will provide power to the load. There will be a power flow animation from PV module and utility icons to battery icon and another power flow from utility icon to load icon.

Inverter mode: Utility power is not available or not connected during this mode. All possible power flows are described as below.

1. If PV power is not available, battery power will provide power to the load.
   There will be a power flow animation from the battery icon to the load icon.

2. If PV power is available and sufficient, PV power will charge the battery and provide power to load. There will be power flow animation from PV module icon to battery and load icons.

3. If PV power is not sufficient, PV power and battery power will provide power to the load at the same time. There will be power flow from the PV module and battery icons to the load icons.

Fault mode: When a fault occurs in the solar inverter, the icon of the solar inverter will flash until the fault is solved.

• Off-Grid Operation:
  There is no power feed-in to the grid. Utility (or generator) becomes one of the power sources.
  Bypass with PV charging mode: If PV power is sufficient, it will charge the battery and AC power will provide power to load. One power flow animation is from PV module icon to battery icon and another one is from utility icon to load icon.
  Bypass with AC charging mode: If PV power is insufficient, AC power will charge the battery and provide power to load. There will-power flow animation from utility icon to battery and load icons.
