I have no AC output on my Growatt 3000 watt 24 volt all in one inverter. The batteries are at 27.4 volts. I have the letters "FC" on the display but there are no fault codes on the display and the fault code light is not flashing or beeping. Power is available from the solar panels. Does anyone have any ideas on how to track down the source of my problem? Thanks

No AC output on Growatt 24 volt 3000 watt all in one inverter
My Growatt 24 volt 3000 watt inverter stopped AC output. I have the letters "FC" on the display but the fault code light is not flashing or beeping. Does anyone have any suggestions to track down the source of the problem? The inverter fan is not running so I don't think that it is...

Is the inverter turned on?
Most of these AIO inverters can actually charge the battery when off.
In order for the inverter part to work (producing AC from battery/solar DC) it needs to be on. Do you have such a switch?

The inverter was on. However, I just now shut it off, disconnected all pv input at combiner box, battery input at battery bank circuit breaker, ac output at ac circuit panel - then turned everything back on. It seems to be working ok now. Thanks for pointing me in the right direction. Maybe this thing is like a Microsoft pc - needs a restart when it gets confused.
