Overvoltage
detected on the DC
input. When the
voltage at the DC
input reads higher
than 16.0±0.5VDC,
the AC output will
shut down.
1. Check that the
voltage at the DC
input terminals do
not exceed 16VDC,
if so, attempt to
lower the voltage of
the battery and
check battery
charging voltages.
2. Ensure that
maximum charging
voltage of any
chargers connected
to the battery are
set below 16.0VDC
3. Ensure that there
are no unregulated
charging sources
such as solar panels
with no regular are
connected to the
battery.
