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).

to the batteries.
Ensure the inverter batteries are
connected and the inverter is
operating correctly without any AC
power connected (can invert and
power AC loads from batteries).
