4.3 Interface Types
Users can perform the corresponding operations with the 4 function keys,
described in Table 4-2, according to the indications of the LCD display.
The LCD screen will display different interfaces based on the operation modes
of the inverter. There are four operation modes: Logo interface mode (as
shown in Figure 4-2), Normal operation and Standby modes (as shown in
Figure 4-3), and Fault mode (as shown in Figure 4-4).
1. The LCD interface starts with the company logo once the system is
energized, as shown in Figure 4-2.

2. While the inverter is in Normal Operation mode (and not in screen saver)
the interface indicates PV voltage, PV current, Grid voltage, instant power,
daily generated power and time. This is the “Default Indication Interface.”
The inverter will enter 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 value. The inverter will check automatically
whether it meets the startup conditions in this mode until it turns back to
