Power grid exception: The

actual power grid

frequency is lower than

the standard requirement

for the local power grid.

1. If the alarm occurs

occasionally, the power grid

may be abnormal

temporarily. The inverter

automatically recovers

after detecting that the

power grid becomes

normal.

2. If the alarm occurs

frequently, check whether

the power grid frequency is

within the acceptable

range. If not, contact the

local power operator. If yes,

modify the grid

underfrequency protection

threshold through the

mobile app, SmartLogger,

or NMS with the consent of

the local power operator.
