E005 Communication Error
No communikation between
Micro and DSP
Inverter Swap
E006 Output Overcurrent
If error occurs randomly: Rapid
change in grid voltage. -> inverter
goes back on line
Permanent error: Problems with
the current measurement
The network parameters verification otherwise
Inverter swap
E007 IGBT Sat
Overcurrent in the bridge: If error
occurs randomly: change of the
grid voltage, leakage current
problem?
Permanent error: HW error
Check the DC insulation. If E007 is displayed before
the grid connection could the cause be a leakage
current.
Otherwise: exchange
