SMA SunnyBoy Solar Inverter Faults and Warnings:
Some of the advice we give related to identifying, confirming and or resolving some of the faults detailed below, starts with safely shutting down and restarting the inverter and the solar PV system. This is something that nearly all solar PV systems installed in the UK would have been designed to be carried out safely by the solar PV system owner. However, paperwork, schematics and manuals are not always clear or available, so if you have any concerns about how to do this, we will always be more than happy to talk you through the process over the telephone at no charge.

How to Restart a SMA SunnyBoy Solar Inverter:
HF Series
AC Isolator
|
Leave everything near the supply meters turned on. At the inverter there will be an AC isolator, this is used to isolate the mains/grid supply from the inverter and to prevent the inverter from feeding solar power into the electrical system. Switch the AC isolator 'off', if the inverter is running correctly you will hear a clunk inside the machine and after a while a 'grid fault', 'missing grid' warning or similar will appear on the LCD display.
Near to the solar inverter might be a method of isolating the solar (DC) supply from the inverter. Often these are black and grey and will be labelled 'DC isolator' or similar. There might be two or more of these if the system is fed by multiple strings.
All SunnyBoy inverters have a built in ESS switch / DC isolator. The TL Series and the older SunnyBoys have a handsized black plastic component on the underside of the chassis. Getting a good grip on this, pulling this straight down will isolate the DC circuits. The HF Series of SunnyBoy inverters have a black plastic piece that runs across the bottom of the inverter. You will find a hand grip in the centre, pulling this straight down will release the whole lower part of the inverter (the black plastic part) and isolate the DC circuits. More modern SMA SunnyBoy inverters have a rotoray style on/off switch to isolate the DC circuits mounted on the left hand side of the chassis.
When all of the lights on the solar inverter have gone out, reintroduce the AC/mains supply by turning the AC isolator 'on'. Introduce the DC supply by reinserting the ESS switch (push straight up) and turn any external DC isolators 'on'.
This will restart the solar inverter, on the display it will show you progress during it's startup procedure. During startup is when the solar inverter carries out all of the tests needed before being able to connect the solar supply to the electrical system. If errors are found during testing they will be displayed on the screen or an indication light might come on. Make a note of any warning messages, warning lights and fault codes.
|
If the restart is succesful a green light will come on, sometimes flashing at first but once connected to the mains/AC supply, remaining permenantly on. The LCD display will show how much power the solar PV system is generating. The solar PV system can be verified as working at the solar generation / Feed in Tariff (FIT) meter which will count on the display, the red light will pulse as it counts.
SMA SunnyBoy Solar Inverter: No lights, No Display
SMA SunnyBoy solar inverters are powered by the solar panels (the DC supply) and will startup at sunrise each day and shutdown at night. If you find the inverter with no lights or display working during the day, there is either a problem with the solar panels or with the inverter. Follow the shutdown and restart procedure outlined above and if the problem persists Contact us to discuss the next steps.
SMA Sunnyboy Solar Inverter Fault Codes and Explanations:
SunnyBoy |
- Event 1 - Grid Fault - The inverter is measuring a grid (mains) voltage or a grid impedence that is too high in relation to the parameters that the inverter has been set to safely operate within. If this fault persists contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter or with the grid.
- Event 2 - Grid Fault - The inverter is measuring a grid (mains) voltage or a grid impedence that is too low in relation to the parameters that the inverter has been set to safely operate within. If this fault persists and mains power is available to other local circuits then check that all isolators, MCBs and RCDs on the AC side of the solar PV system are 'On'. If automatic safety devices such as MCBs or RCDs have switched 'Off' then leave them 'Off' and contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter, the supply circuit or with the grid.
|
- Event 3 - Grid Fault - The inverter has measured a 10 minute average grid (mains) voltage or a grid impedence that is too high in relation to the parameters that the inverter has been set to safely operate within. If this fault persists contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter or with the grid.
- Event 4 - Grid Fault - The inverter is no longer in grid parallel operation due to frequency fluctations from an unstable grid (mains) connection and has stopped feed‑in operation for safety reasons. If this fault persists contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter or with the grid.
- Event 5 - Grid Fault - The inverter is measuring a grid (mains) frequency that is either too high or too low in relation to the parameters that the inverter has been set to safely operate within. If this fault persists contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter or with the grid.
- Event 6 - Grid Fault - The internal monitoring function of the inverter has detected an excessively high proportion of direct current in the grid current. If this fault persists contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter or with the grid.
- Event 7 - Frq. not permitted - The inverter is measuring a power frequency outside the permissible range that the inverter has been set to safely operate within. If this fault persists contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter or with the grid.
- Event 8 - Waiting for grid voltage - Grid Failure - Check Fuse - The inverter understands that there has been a mains failure (a power cut). If this fault persists and mains power is available to other local circuits then check that all isolators, MCBs and RCDs on the AC side of the solar PV system are 'On'. If automatic safety devices such as MCBs or RCDs have switched 'Off' then leave them 'Off' and contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter, the supply circuit or with the grid.
- Event 9 - PE conn. missing - Check connection - The inverter understands that the protective earth connection is missing from the AC supply side. If this fault persists and mains power is available to other local circuits then check that all isolators, MCBs and RCDs on the AC side of the solar PV system are 'On'. If automatic safety devices such as MCBs or RCDs have switched 'Off' then leave them 'Off' and contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter or the supply circuit.
- Event 10 - L / N swapped - Check connection - The inverter understands that the Live and Neutral connectors are swapped on the AC supply side. This fault is unlikely to occur in an existing installation that has previously worked correctly. If this fault persists contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter or the supply circuit.
- Event 11 - Installation fault - Check connection - The inverter understands that either the Live and Neutral connectors are swapped on the AC supply side or the second phase has been connected to the Neutral on a three phase circuit. This fault is unlikely to occur in an existing installation that has previously worked correctly. If this fault persists contact us to arrange for an engineer to visit to establish whether the fault lies with the inverter or the supply circuit.
- Event 33 - Unstable operation - The inverter is measuring low DC voltage. Assuming that there is adequate sunlight, this is an existing installation that has been specified correctly, no changes near the installation area have been carried out and the system has operated before without problems, if this error persists then we would advise that the DC side of the system including and excluding the inverter is tested.
- Event 34 - DC overvoltage - Disconnect generator - The inverter is measuring too much voltage from the solar panels. Assuming that this is an existing installation that has been specified correctly, hasn't recently been changed or added to and has operated before without problems. This could mean either a problem with the solar panels or with the inverter. We would advise that the DC side of the system is disconnected using either the built in DC isolator at the bottom of the inverter or the DC Isolator installed between the solar panels and the inverter (if available) and contact us to test the DC side of the system including and excluding the inverter.
- Event 35 - Insulation resist - Check generator - This error is generated when during normal operation of the inverter, a leakage current to ground/earth is detected on the DC side of the system. Earth / Ground Faults (also called Iso or Isolation Faults) often present themselves when it is raining or at times of high humidity when moisture can enter the system.
These faults often clear when conditions improve but they will not get better by themselves, potentially becoming more dangerous over time. We would advise that you book an engineers visit in order to carry out a full system test, identify the source and rectify the fault.
