Figure 5-7 Inverter system in standby
(3) Normal operation mode, as shown in Figure 5-8:
The inverter will turn from standby into normal operation
mode when the output voltages of PV panel and power grid
meet the startup conditions as long as the inverter is “ON
State”. In this mode, the inverter converts the power
generated by PV modules to AC continuously and feeds to
the power grid. During the grid connection and power
generation, the inverter will maximize the output energy of
PV panel in the manner of MPPT (Maximum Power Point
Tracking). Meanwhile, the inverter will check the power grid
and PV voltage constantly. Once any abnormality happens,
the inverter will stop running and take self-protection.
