MOUNTING THE INVERTER Installation Tools The following tools are required for inverter installation: Crimper, Cable Ties, Cutter, Drill, #2 Phillips Screw Driver, Slotted Screw Driver, Tape Measure, Wire Cutters, and Wire Strippers. Inverter Mounting Recommendations NOTE: The inverter mounting location should provide adequate ventilation and clearance to maintain room temperature during operation. At least ½” of clearance is required on all sides. 1.
Mounting for Model: 24NP36 (units are in inches) 9
DC WIRE GAUGE & FUSING Inverter Cable An “Inverter Cable Kit” (positive cable, negative cable, and proper fuse) is needed to connect the inverter to a battery bank. An 8-guage single strand cable is also recommended to connect the inverter’s bonding lug to ground. The inverter cable length and the size of the inverter will determine the cable gauge and the fuse size to use. The maximum inverter cable recommended is 20-ft; it must be fused within 18-in from the positive (+) terminal of the battery.
AC INPUT & OUTPUT CONNECTIONS WARNING: Do not connect another source of AC power directly to the output of the inverter. This will result in damage not covered under warranty. Tighten to 14.6 in/Lbs The inverter’s 120 VAC output power is provided at the GFCI receptacle and the hard wire terminal blocks behind the access panel. Wire the AC Input to the hard wire terminal blocks behind the access panel for charging and shore power. NOTE: Remove the black hole covers as needed for hardwire AC wiring.
REMOTE STATUS PANEL & REMOTE INV. ON/OFF SWITCH Remote Status Panel The display panel can be removed from the inverter and installed in a different location in the vehicle for remote control and monitoring. Please follow the following procedure closely. Unscrew the two screws that hold the panel in using a 3/32” allen wrench. Disconnect the RJ45 connector from the back of the remote panel and re-connect it to the backside of the replacement RJ45 cover plate.
WIRING DIAGRAM 24VDC Typical DC Wiring Diagram 13
OPERATION (Using LED Display Panel) Once the inverter has been fully installed and wired, and DC power has been applied, the 7 segment display panel will come to life. This display panel shows the status and configuration information of the inverter and charger. You can also turn the inverter on and off by pressing the [ON/OFF] key and also make configuration changes using the [MENU] and [DISPLAY/SELECT] keys.
2) Inverter “Stby” The inverter standby feature allows the inverter to automatically come on anytime that it senses a loss of shore power and then go back to standby when shore power is returned (after 22 seconds of line qualify time). This feature is enabled by turning the inverter on by pressing the [ON/OFF] key.
press the [DISPLAY/SELECT] key. The display will show “LO BATT” followed by the recorded minimum low input condition (trough) voltage. The mode will stay active for 1 minute or until the [BATT TEST] or [MENU] key is pressed. The following message shows the low point at 20.2 volts. Lo batt 20.2v If there is not a value stored, the message will just say “Lo batt ---” and not list any voltage. You can clear the stored value manually by pressing the [DISPLAY/SELECT] key while the message is scrolling.
2) AC Input Limit (Charger AC current limit) The maximum AC current that the charger will be allowed to draw is adjustable. This value can be set to 30-0A (maximum value is factory set based on model). The default setting is for 15 amps. Press [MENU] to display the current setting. The message will then scroll: AC In Lmt 15A To change the value press [DISPLAY/SELECT] and the value will decrease in 5A increments. The charger stores the last value shown on the display.
OPERATION (Using Remote ON/OFF tab) Once the inverter and remote On/Off switch have been fully installed and wired, and DC power has been applied, the inverter is ready to turn on. The Status LED on the right side of the inverter shows the status information of the inverter and charger. Inverter Power Mode (Using Remote ON/OFF tab) 1) Turning the Inverter “ON” or “OFF” (no AC applied): The inverter can now be turned on by turning on the remote switch.
THEORY OF OPERATION Inverter Power Mode Usage: Any 120 VAC, 60 Hz single phase product within the inverter’s power rating. The Display Panel [ON/OFF] key or a voltage between 8 and 34 volts applied to the “Remote On/Off” input controls the inverter. Operational modes: “External Power” mode and “Inverter Power” mode. The LED Display Panel “ON/STBY” LED will be on Green and the Status LED will blink Amber while the inverter is on.
Battery Charger: The battery charger will engage automatically and independently of the inverter ON/OFF status. The 3-step charging process modes are; Bulk, Acceptance, and Float. The LED Display Panel will show charger mode and the Status LED located on the side of the inverter will blink Green to indicate the charging process mode (1 blink = Bulk, 2 blinks = Accept, 3 blinks = Float). NOTE: The charger is capable of charging AGM, GEL, or Wet cell batteries.
Charger operation with temp comp bypass dongle: Proper battery charging is best achieved by the use of the temperature compensation cable. If this is not feasible then the temperature compensation dongle can be used. If the charger is used with the Temp Comp Cable Bypass Dongle, the charger will lock in to a hot setting for the charge voltages per the table.

5) Charger Off High Temperature chgr OFF high temp The charger is off due to a high temperature condition (>60°C/140°F). The Red “FAULT” LED is on. The charger will turn back on automatically when the temperature is < 45°C/113°F. 6) Charger Off Battery Temperature chgr OFF batt temp The charger is off due to a high battery temperature (>47°C/117°F50°C/122°F). The Red “FAULT” LED is on. Check the battery compartment for proper ventilation.

Troubleshooting 4) No AC output power during inverter mode: No LED’s On: • Check the in-line fuse which is located within 18” from the battery’s positive post. • DC connections tight and clean? • Battery voltage to be above 21 VDC? • Check Remote Power Switch. LED blinks Amber once: Disconnect all loads and connect a test light to the GFCI outlet.
APPENDIX Ignition Switch Control with the LED Display Panel The LED Display Panel can be wired to the vehicle ignition circuitry to control operation of the inverter. When the ignition is turned on, the inverter has a builtin delay which will turn it on after 10 seconds. In order for the inverter to work in this way the LED Display Panel must be programmed for this type of operation.
