Introduction
Inverter Safety Instructions
WARNING: Customer must match battery type with charger battery type.
WARNING: Power inverters produce hazardous voltages. To avoid risk of harm or re, the unit must be
properly installed.
WARNING: There are no user serviceable parts inside. Do not remove the cover.
WARNING: Power inverters should not be mounted in a location that may be exposed to rain, spray, salt, or
corrosive chemicals.
WARNING: Power inverters should not be installed in a zero-clearance enclosure.
WARNING: Damage to the power inverter will occur if correct polarity is not observed when installing the
inverter’s DC input cables.
WARNING: Damage to the power inverter will occur if an external AC power source is applied to the inverter’s
AC hardwire output.
WARNING: Power inverters contain a circuit breaker and capacitor that may produce a spark upon connection
or during normal operation. Do not mount in a conned battery or gas compartment where toxic fuel vapor is
present.
WARNING: Be sure that the power inverter is turned off and AC power is disconnected when batteries are
being connected, disconnected, serviced, and replaced or personal injury and/or damage to the inverter could
result.
WARNING: Working near lead-acid batteries is dangerous. There is a risk of acid exposure.
Battery Safety Instructions
WARNING: Batteries may vent explosive gases during operation.
WARNING: There is risk of high current discharge from shorting a battery that can cause re and explosion.
Use insulated tools during installation.
WARNING: Remove all rings, watches, jewelry, or other conductive items before working near the batteries.
WARNING: Inspect the batteries at least once a year for cracks, leaks, or swelling. Follow the scheduled
maintenance procedures from the battery manufacturer.
WARNING: Dispose of the batteries according to local regulations. Do not incinerate batteries; there is risk of
explosion.
WARNING: A fuse must be installed between the battery and the inverter to protect against shorted cables.
WARNING: If multiple LFP batteries are connected in parallel, the maximum charger current shall not exceed
the maximum rated charge current of a single battery. This is to prevent overcharging into one battery if
any other battery disconnects during charging. Failure to limit the charge current may result in the battery
disconnecting due to overcurrent and/or may damage the battery.
WARNING: Only use LFP batteries that utilize a BMS that shuts down the battery due to over-current, high
temperature, and cold temperature.
WARNING: The converter/inverter is intended to recharge batteries. The battery that is connected to this
product is only suitable if it complies with the given battery standard for that battery type and is provided with
a battery management system that will monitor and control the electrical and thermal health of the battery
during charging. When installing this converter/inverter, the battery is to be veried as in compliance with the
applicable battery standard.

Design Features
• DC Input: Connects to the 24 VDC battery bank.
• Bonding lug: Connects to the system ground.
• AC Input & Output (Hardwired): Terminal blocks are provided behind front access cover for hardwiring AC
Input and Output. A second set of openings to access the AC terminals can be found on the underside of the
inverter/charger when using the large chassis.
• AUX Connector: Currently not used in standard conguration. Mating connector sold separately.
• Remote Switch Wiring Tab: Terminal is used to wire a customer supplied snap style “On/Off ” switch.
NOTE: The 7-Seg display can also be used as a remote. Order remote LCD panel kit# 625000. Alternatively, the
“R” sufx version of the inverter can also be provided with a simple “On/Off ” switch in place of either remotes.
See the “L” option in the Appendix.
• Status LED: This LED will show the operation mode and troubleshooting information. See the table in the
troubleshooting section at the rear of the manual for further mode descriptions.
• 7-Segment Display: Provides limited local control and status of the inverter/charger. The 7-Seg display or an
LCD remote may be purchased separately as a remote. See the “R” option in the Appendix.
• GFCI: Outlet protection; 20 A self-testing receptacle.
• GFCI Output Breaker: Trips to protect the GFCI from shorted AC loads or overload situations.
• Output Breaker: Trips to protect the internal circuitry from shorted AC loads or overload situations. Rated for
30 A.
• BTS: Allows for proper temperature charging across the operating range of the inverter.
• CAN Port: DB9 port used for CAN control of inverter/charger.
• AUX Ports and Connectors: Currently provides no function. May be lled with blank plugs.
• Thermally Controlled Cooling Fan
• Low Battery Protection: Automatically shuts down the inverter at 21.0 VDC with inrush delay.
• High Surge Rating for Large Motor Loads
• Rugged Design for RV/Mobile Environments
• Battery Conguration: Standard models are congured for use with AGM batteries (for charging). Options
for battery type include wet, AGM, gel, and LFP (lithium iron phosphate or LiFePO4). Additionally, there
are four battery prole options for LFP. The battery type may be changed using the optional LCD remote or
through the RV-C CAN tool.
Contact the factory for updated information or for other voltage, current ratings, and battery congurations that
may be available.

Installation
24NP Manual
INSTALLATION
Mount the Inverter
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 except the bottom. This includes ½”
beyond the mounting anges and DC terminal covers.
Installation Tools
The following tools may be required for inverter installation:
• Wire Termination Crimper
• Cable-Ties
• Drill
• 9/16” Socket or Open Ended Wrench
• Phillips Screwdriver
• Tape Measure
• Wire Cutters
• Wire Strippers
• 3/16’’ Slotted Screwdriver
1. Locate a suitable, secure, vertical or horizontal mounting surface as close to the batteries as possible without
being in the same airtight compartment.
2. Mount the inverter using four ¼-20 steel bolts, at and lock washers, and nuts. The length of the bolts should
be equal to the mounting material thickness plus ¾”.
