Solution

pressed
Dust / dirt buildup inside of the
LCD user interface.
Remove the LCD user interface and

LCD is nonfunctional (no
lights, or text on LCD
screen, and no response
when pressing any button).
Communications cable is bad
or not connected correctly to
the LCD port on the inverter.
Check communications cable from
inverter to LCD; ensure (1) it is
connected to the remote port and
(2) the correct communications
cable is used. (A four-conductor
telephone cable may be substituted
to determine if the cable is good).
PRO-Verter is not connected
to the batteries or the batteries
are overdischarged.
Ensure the System batteries are
connected and the inverter is
operating correctly without any AC
power connected (can invert and
power AC loads from batteries).
No crossover cable or
incorrect cable installed
between the two ports on the
RMK.
See PRO-Verter Remote Monitoring

power from inverter.
Ensure batteries are connected and
the inverter is operating correctly;
the inverter should be able to invert
