What to do if SolarEdge SE3K-RWB server ping failed?
If the ping or connection to the SolarEdge server failed, verify the SolarEdge server address under the LAN Conf submenu. The address should be prod.solaredge.com and the port should be 22222. Check with your network administrator to ensure that a firewall or other device isn't blocking the transmission.
What to do if SolarEdge Inverter string voltage is higher than number of optimizers?
If the string voltage is higher than the number of optimizers, first check if an extra power optimizer is connected in the string. If not, verify that only power optimizers are connected in the string and that no module outputs are connected without a power optimizer. If the issue persists, disconnect the wires connecting the power optimizers in the string and measure the output voltage of each power optimizer to find the one that does not output 1V safety voltage. If a malfunctioning power optimizer is located, check its connections, polarity, module, and voltage. Contact SolarEdge Support if needed.
What to do if SolarEdge SE3K-RWB Inverter string voltage is not 0V but lower than number of optimizers?
If the string voltage is not 0V but lower than the number of optimizers, ensure all power optimizers are connected. Also, check that the panels are properly connected to the power optimizer inputs. Finally, check the string polarity using a voltmeter and correct it if needed.
What to do if SolarEdge SE3K-RWB Inverter gateway ping failed?
If the ping to the router failed, check the physical connection to the switch/router and ensure the link LED at the router/switch is lit. If the connection is OK, contact your network IT. Otherwise, replace the cable or change it from a cross to a straight connection.
Why is my SolarEdge SE3K-RWB Inverter showing LAN disconnected?
A 'LAN Disconnected' message indicates a physical connection fault. Check the cable pin-out assignment and cable connection. Refer to Creating an Ethernet (LAN) Connection on page 69.
What to do if SolarEdge SE3K-RWB string voltage is 0V?
If the string voltage is 0V, it indicates that the power optimizer output is disconnected. Connect all power optimizer outputs.
What to do if SolarEdge SE3K-RWB Inverter DHCP failed or invalid config?
If DHCP failed, or the DHCP configuration is invalid, it indicates an IP settings issue. Check the router and inverter configuration. Consult your network IT.
What to do if SolarEdge SE3K-RWB follower detect is smaller than the actual number of Followers?
To solve this problem, use the Long Follower Detect to retry connecting to followers. Also, analyze the Follower List to check for missing followers and check their connection.
