Error Codes 1-11 and 39

These errors are permanent faults. To try and correct these faults, disconnect the inverter from the utility grid and the PV array. After 3 minutes, reconnect the inverter. If the fault continues to be displayed, please contact your local technical support team for assistance.

Error Code 51

This fault relates to power distribution. If you see this error code, open the inverter box and check the power distribution to see if a fuse has been damaged.

Error Codes 49 and 50

This fault relates to power distribution. If you see this error code, open the inverter box and check the power distribution to see if the signal cables for the PV1-SPD and PV2-SPD surge protectors have been disconnected. If they are disconnected, reconnect them. If the fault persists, please contact your local technical support team for assistance.

Error Code 46

This fault relates to the maximum DC input voltage of the inverter. Check the open-circuit voltages of the strings and make sure that they are lower than the maximum DC input voltage of the inverter. If the input voltage is within the permitted range and the fault persists, the internal circuit may be broken. In this case, please contact your local technical support team for assistance.

Error Codes 41-45

Disconnect the inverter from the grid and the PV array, then reconnect it after waiting 3 minutes. If the fault persists, please contact your local technical support team for assistance.

Error Code 40

This fault relates to the maximum operating temperature for your inverter. If you see this error code, check to ensure that the airflow to the heat sink is unobstructed and check to make sure the ambient temperature around the inverter isn’t too high.

Error Code 38

Check to ensure that the PV array is grounded and make sure the insulation resistance is greater than 1 MOhm. Verify that the inverter’s grounding connection is reliable. Also, make a visual inspection of all PV cables and modules. If the fault persists, please contact your local technical support team for assistance.

Error Code 37

Check the open-circuit voltage of the strings and make sure it does not exceed the maximum DC input voltage of the inverter. If the input voltage value is within the permitted range but the fault persists, please contact your local technical support team for assistance.

Error Code 36

If you see this fault, ensure that the grounding connection of the inverter is intact and reliable. Conduct a visual inspection of all PV cables and modules for any breaks or defects. If none are found but the error code persists, please contact your local technical support team for assistance.

Error Code 35

If you see this error code, there are a few things you will need to check. First, verify that the fuse and the triggering of the circuit breaker in the distribution box are functioning properly. Second, check the grid voltage and grid usability. Third, check the AC cable and make sure the inverter is connected to the grid. If the fault persists after you’ve checked these three things, please contact your local technical support team for assistance.

Error Code 34

Check the grid voltage at the connection point on the inverter. If the grid voltage is outside the accepted range of local grid conditions, modify the values of the monitored operational limits, but only after informing the local electric utility company. If the grid voltage is within the permitted range and this fault persists, please contact your local technical support team for assistance.

Error Code 33

Frequent power fluctuations could cause this fault so check the grid frequency and make a note of how often major fluctuations occur. If major fluctuations are frequent, try to modify the operation parameters after informing the local grid operator.

Error Code 6

This fault relates to the maximum DC input voltage of the inverter. Check the open-circuit voltages of the strings and make sure that they are lower than the maximum DC input voltage of the inverter. If the input voltage is within the permitted range and the fault persists, the internal circuit may be broken. In this case, please contact your local technical support team for assistance.

How can I engage the inverter’s power management functions?

All of our inverters have some basic power management functions by default since they’re usually required by local power grid regulations.

You can increase the power management function with one of our data loggers. After the installation of a data logger, you can log in to our app, our web server, or our cloud service to set the active/reactive power value, the fixed power factor, or the reactive power curve to control power.

It is possible to send instructions to the inverter and control the power output in real time using a third-party control device like a radio ripple control receiver (RRCR) or a demand response enabling device (DRED) connected to AiComm.

For more details, please refer to the user manual for your specific inverter, or contact your local technical support team for guidance.

How do I select the right Solplanet data logger for my installation?

Solplanet has several data logging solutions suitable for use on a variety of PV installations.

If you have a residential installation, our Wi-Fi stick could be your perfect option. It installs on the bottom of the inverter housing using a quick plug-in connection and can support one inverter.

If your installation is larger, perhaps a commercial or industrial setup, your best option might be an AiComm. It too installs on the outside of the inverter housing, but it connects to a router via WiFi and can support up to five inverters.

Contact your local Solplanet team for assistance in choosing which data logger is right for you.

Do Solplanet inverters support third-party data loggers?

Yes, Solplanet inverters support third-party data loggers like Solarlog, Meteocontrol, and Solarman. For large-scale PV installations, we can offer our protocol to a third party to be used to develop their own customized monitoring solution.

Does the AISWEI Cloud provide weather data?

No, the AISWEI Cloud does not obtain or record weather data like irradiation levels, temperature, or wind speed. If you need to monitor the weather to support your PV installation, you can either purchase an independent weather station or use a third-party solution (like Solarlog, Meteocontrol, and Solarman).

Can I install an AiComm in an outdoor environment?

Yes, you can. However, because of outdoor weather conditions, an AiComm must be installed within an IP65-rated enclosure.

Can I use a computer without an internet connection to monitor my Solplanet inverter?

No, our inverters do not support local monitoring. Our monitoring solutions (either a GPRS stick, WiFi stick, or AiComm) upload inverter data to the Solplanet Cloud and that requires a stable and reliable internet connection. If required, we can supply our communications protocol to our customers so they can develop their own monitoring systems.

Where will my data be stored?

Your privacy is one of our top concerns and we take it very seriously. Once you permit us to collect your data, it will be stored in compliance with privacy laws in your country.

If you have concerns about how we collect and store your data, please don’t hesitate to contact your local Solplanet team.
