Chapter 6 Operation

6.1 Start-up

Manual start-up: Manual start-up is required after regulation setting or

manual (fault) shut-down. Move the cursor from the main operation interface

to “4 Setting”. Press ENT and go to submenu “1 ON/OFF”. Then move the

cursor to “ON” and press ENT to start the inverter. Then the inverter will start

up and operate normally if the start-up condition is met. Otherwise, the inverter

will go to stand-by mode.

Automatic start-up: The inverter will start up automatically when the

output voltage and power of PV arrays meet the set value, AC power grid is

normal, and the ambient temperature is within allowable operating range.

6.2 Shut-down

Manual shutdown: Normally, it is not necessary to shutdown the inverter,

but it can be shut down manually if regulation setting or maintenance is

required.

Move the cursor from the main operation interface to “4 Setting”. Press

ENT and go to submenu “1 ON/OFF”. Move the cursor to “OFF” and press

ENT, and then the inverter will be shut down.

Automatic shutdown: The inverter will be shut down automatically when

the output voltage and power of PV modules are lower than the set value, or

AC power grid fails; or the ambient temperature exceeds the normal range.

6.3 Operation mode

There are 4 operation modes. The following are corresponding indications

for each mode.

(1) System check mode for start up, as shown in Figure 6-1:
