The slave DSP detects
that the grid frequency
exceeds inverter
allowable upper limit.

2. If the grid frequency exceeds the
permissible range of inverter protection
parameters,
ask utility grid company for
solution.
3. If the grid frequency is within the
permissible range, contact Sungrow Service
Dept.
056
The slave DSP detects
that the leakage
current exceeds
inverter allowable
upper limit.
