Status LED Code Descriptions

Normal Operation

: Inverter communications are operating normally.

Serial Communication Fault: The communication PCB in the inverter communicates

with the inverter’s main processor via serial communication. If the communication PCB

cannot establish communication with the main processor, the Serial Communication

Fault code will ash.

Note: It is normal for this status code to ash for a few seconds during startup.

DNS Failure: The inverter uses a DNS (Domain Name Service) server to resolve the IP

address of the PV Powered database when it posts the data, once every 15 minutes. If the

DNS server cannot be found, or does not return a valid IP address, the DNS Failure code

will ash for a minute or so while the inverter is trying to post. After several retries, the

inverter will try to force a post to a hardcoded IP address. If this post succeeds, the LED

will go back to normal operation until the next post again tries to connect to the DNS

server.

Network Connection Fault: This status code ashes when the inverter cannot post data

to the PV Powered database server. The Network Connection Fault status code starts

ashing only after the inverter has tried to post data to the PV Powered server. The Status

LED may indicate normal operation before this occurs. This can happen in the following

circumstances:

• The network cable is not connected.

• The network does not have a DHCP server or the DHCP server did not give a valid

IP address to the inverter.

• The PV Powered server is down for maintenance.

• Any other network problem that does not allow the post to make it to the PV Pow-

ered server.

Modbus LED Operation and Signaling

If the inverter is connected as a slave device on a Modbus network, the Modbus LED

will ash quickly whenever there is activity on the network. The quick ashes will be

seen even if the Modbus commands are not addressed to the inverter. These quick ashes

enable the installer to troubleshoot the system by verifying that communications are

occurring on the network. If the inverter sees and responds to a message that is addressed
