March 18, 20233 yr I am using a Growatt 5000 es inverter fixed 7 months ago For the last two weeks we hear a beep noise from the inverter On examination we find that the solar line in display is interrupted ( connected and disconnected) very often Once it is disconnected we get a beep noise No error code is shown and no error messages are coming Although the inverter is working the solar production is very less PV line is checked but reported no issues will anyone help to resolve this issue
March 18, 20233 yr Two possibilities in my view. Physical intermittent disconnect of Solar DC supply, i.e. a marginal connection that drops out with load/temperature, or an MPPT that is faulty. Put a voltmeter on the DC input and monitor.
