compatibility requirements. Before leaving the factory,all inverters have
had a rigorous testing to ensure the long time
If a fault occurs, LCD and LED will be prompted show
fault information.Under the condition of alarm, inverter
may stop power.The fault table are shown in table 7.1
below:
Safety hints：
If your SUN – 5k string type inverter appeared any
fault information as shown in table 8-1, and after the
restart still not eliminate the fault, please contact your
local dealer or service center.You need to prepare the
following information.:
1. Inverter serial number.
2. Inverter distributor or service centre (if any);
3. Date of start grid tie.
4. Description (including fault code displayed on the LCD and light) in
detail as much as possible.
5. Your contact details
In order to make you more clear understanding of the inverter fault
information, We put all fault code and instructions in below table
the inverter is not normal working.
