In this mode, the inverter converts the power generated
by PV modules to AC continuously and feeds into the power
grid.
(3) Standby mode, as shown in Figure 4-3:
The inverter will turn into standby mode when the output
voltage and power of PV modules do not meet the startup
conditions or PV voltage and input power are lower than the
set point. The inverter will check automatically whether it
meets the startup conditions in this mode until it turns back
to normal mode. The inverter will switch from standby mode
to fault mode if malfunction occurs.

(4) Fault mode, as shown in Figure 4-4:
The inverter will disconnect from the power grid and turn
into fault mode when the inverter or power grid fails. Check
the specific cause through “Troubleshooting table” (Table 4-1)
in terms of the fault message displayed on the LCD and
eliminate the fault according to the instructions.
