[QUOTE="Barx, post: 527437, member: 121"] Are you sure it just says 'grid fault'? According to the manual, there isn't such a fault message. You have: Grid Lost Fault Grid Volt Fault Grid Freq Fault Wouldn't be the first time I have seen inverters crap out due the grid voltage being too high. If there is a load of PV systems installed locally, they can raise the voltage of the grid, all fighting to feed back. Would make sense with it happening during good production times too. Also, as above, could be a poor connection that is breaking / making. This too could be more prevalent during good production as the current flowing will be high and more likely to warm the joint up. If it is a bad connection (Grid Lost). My money is on either breaker not connected to bus bar properly, or loose terminal in one of the AC Isolators. [/QUOTE]
