The model in the firmware code does not
match the physical model, please contact
customer service for further check.
1. If it occurs in weak light conditions (such
as early morning or dusk, and extreme
weather such as rain and sandstorms), it is
a normal phenomenon that the compo-
nent voltage is low at this time, and no
need to deal with it..
2. If it occurs under the condition that the
light is normal, please check whether there
is a short circuit or open circuit in the solar
panel string connection.
1. If the alarm occurs occasionally, possibly
the external circuits are abnormal acci-
dentally. The inverter automatically recov-
ers to the normal operating status after the
fault is rectified.
2. If the alarm occurs repeatedly or last a
long time, check whether the insulation re-
sistance against the ground of solar panel
strings is too low.
