3.6 Communication
There are two types of communication methods, RS-232 and RS-485 supported in the SE inverters that may be connected to an external
computer or terminal equipped with either RS-232 and/or RS-485. Only one type of the communication can be used at a time. SE inverter
will automatically switch to RS-232 or RS-485 depends on the external communication interfaces without manual setting. For the RS-485
interface, it allows multiple inverters that can be connected to an external computer. It allows only one inverter to be connected to an external
computer if RS-232 interface is used. Please refer to the section 2.3, “Connection of the Communication Cable”, for the detail pin descriptions
for both RS-232 and RS-485 interfaces.
3.7 Explanations of Error Messages
In the event of a fault, the inverter will stop feeding the AC power to the utility grid and display the error message on the LCD. Qualified service
personnel shall do the analysis, measurement, and debug if needed according to the error message in order to resume normal conditions. It
is recommended to screen out the fault condition(s) by referring to the table below and then remove the fault condition(s) to return normal
condition and continue to feed AC power to the utility. Please contact Siliken Electronics or your service representative if the same error
message is persistent.
