On a Sunny Island, warnings W724, W725 or W726, or event 6133 or F710, mean the unit has hit its maximum number of autostarts. In other words, it has restarted several times in a row on L1, L2 or L3. Autostart restarts the unit automatically after a malfunction. If one attempt fails, the next one starts right away, but the total number of attempts is limited. Once the limit is reached, the Sunny Island waits ten minutes, resets the autostart counter and tries again. It repeats this cycle each time the limit is reached. This warning is a result of another fault, not the root cause. Read the pending and logged warnings and faults, for example in Sunny Portal, and fix the fault that keeps causing the restarts. The generator has its own restart-attempt setting, GnAutoStr. It can also be set from 0 to 10 and defaults to 3. If the cause is not clear, the owner should contact the installer for further investigation.

On Sunny Island devices this shows as warning W724, W725 or W726 (one per line or slave, L1/L2/L3), or as event 6133 or F710. Each means the maximum number of autostarts has been reached.
