with DC applied
• Inverter internally
damaged
• Do not turn off the DC switches as it may
damage the inverter.
• Please wait for sunset and confirm the string
current is less than 0.5A with a clip-on ammeter
and then turn off the DC switch. String current
above 0.5A is under load.
• Note: Damage due to wrong connections or fire
caused by removing string wires or opening
fuse holders under load is not covered in the
device warranty.
Reve-DC
• Please check the inverters’ PV string polarity,
if there are strings reversely connected wait for
the night when the solar irradiance is low and the
PV string current down below 0.5A. Turn off the
two DC switches and fix the polarity issue.
• If string polarity is correct, please confirm that all
the PV strings have the same number of modules.
If not, please modify the system configuration.
• One of the DC string is
reversely connected
• OR different number of
modules are connected
to the string inputs
(Threshold varies between
different conditions)
