4 Installation
The maximum distance between the inverter at the end of the daisy chain and the Data
logger should be within 1000m.
It is recommended to use the RS485 communication cable with a cross sectional area of
0.75-1.5mm2 and an outer diameter of 5mm-10mm.
RS485 cable requirements: Shielded twisted-pair cable or shielded twisted Ethernet ca-
ble.

5 Start and Stop

※ 5.1 Start the Inverter
When starting the inverter, follow these steps:
① Turn on the AC breaker fi rst (close the AC circuit breaker).
② Turn on the DC switch in the bottom. If the PV string voltage higher than the inverter
start-up voltage, the inverter will start.
③ When both AC and DC power supply are normal, the inverter is ready to start. The in-
verter will initiate checking its internal parameters and grid parameters, if it is within the
range, the green light on the left side of the screen begins to fl ash, and the "Waiting" mes-
sage will be displayed on the OLED display.
④ After self-checking completed, the inverter will start generating electricity, the green
light will remain on, and the OLED display will display real-time power information.
※ 5.2 Stop the Inverter
When turning off the inverter, please follow the steps below:
① Turn off the AC breaker fi rst.
② Wait 30 seconds and then turn the DC switch to the "OFF" position. At this time, there
is remaining power in the inverter capacitor. Wait for 5 minutes until the inverter is com-
pletely de-energized before conducting any work on the inverter.
③ Disconnect the AC and DC cables.
