3701 Resid.curr.too high The inverter has detected a residual current after brief
grounding of the small wind turbine system.
Corrective measures:
• Check the small wind turbine system for ground
faults (see Section 11.4).
3801 to
3802 DC overcurrent
Check generator Overcurrent at the DC input. The inverter briefly interrupts
feed-in.
Corrective measures:
• If this message is frequently displayed, ensure that
the small wind turbine system is correctly rated and
correctly connected to the rectifier.
• Ensure that the DC inputs on the inverter are
bridged (see Section 6.4.3).
3901 to
3902 Waiting for DC start
conditions
Start cond. not met The conditions for the feed-in to the power distribution
grid have not been met.
Corrective measures:
• Wait for stronger wind, if necessary reduce the
critical voltage to start feed-in. To do this, change
the parameter Critical voltage to start feed-in or
A.VStr.
• If this message is frequently displayed at medium
wind conditions, ensure that the small wind turbine
system is correctly rated.
