Input Voltage

The input voltage limits are shown in the following table.
Operating condition
Normal
Peak performance
Low voltage alarm
Low voltage shutdown
High voltage shutdown
Unit restarts after low
voltage shutdown

REMOTE CONTROL

An optional remote can be purchased for the PW600, PW900 and PW1800,
P/No. PWREMOTE.
To install the remote control, insert the plug into the data socket on the
front panel.
The remote has the ability to turn the inverter on and off remotely and indicate
when the inverter is on.

Voltage range Comments
11.0V – 14.0V –
13.0V – 14.0V –
10.5±0.3V The audible low battery alarm sounds.
10.0±0.3V The unit shuts down to protect the battery from
being over-discharged.
Voltage is 15.5V The unit shuts down to protect itself from excessive
or more input voltage. Note: Although this incorporates
over-voltage protection, it can still be damaged
if input voltage exceeds 16V.
11.6±0.3V The unit will not restart unless the battery voltage is
acceptable for running the load.
Possible Cause
Poor DC wiring and/or poor
battery condition
Over-voltage(high input) shutdown
Overload shutdown
Over-temperature shutdown
Short circuit
The unit is off
No power to the inverter
Inverter fuse is open
Reverse DC polarity
Solution
Use proper cable and make secure
connections. Charge the battery or
install a new battery.
Make sure the inverter is connected
to a 12V battery.
Reduce the load within the inverter's
continuous power rating.
Improve ventilation and make sure
the inverter's ventilation openings
are not obstructed. Reduce the
ambient temperature, if possible.
Check the AC wiring for a short
circuit.
Turn the inverter on.
Check wiring to the inverter.
Have a qualified service technician
check and replace the fuse if
necessary.
Have a qualified service technician
check and replace the fuse, making
sure to observe correct polarity.
