Installation
AC OUTPUT INSTALLATION:
⚠️ WE RECOMMEND THIS INSTALL IS DONE BY A LICENSED ELECTRICIAN ⚠️
Before installing the inverter into your system, ensure the unit is switched off and that there are no devices plugged into the AC 240V outputs.
A diagram illustrating the connection of appliances to the inverter's AC 240V output sockets. A prominent warning advises that installation should be done by a licensed electrician. Text indicates this step must be completed before installation.
THIS STEP SHOULD BE COMPLETED BEFORE INSTALLATION
CHASSIS GROUNDING:
Grounding of the inverter is mandatory before use to prevent damage or injury. Locate the grounding point on the provided mounting bracket near the negative terminal of the inverter. Ground the inverter by securely attaching a copper cable which is at least 4mm². Connect the other end of the mentioned copper cable to a suitable earthing point, such as your vehicles frame or the grounded negative terminal of the battery. Please consult a licensed electrician to ensure your application meets Australian / New Zealand standards.
CONNECTING THE BATTERY:
- Before connecting the inverter to a battery, ensure you have the correct cable sizes and fuses.
- Begin by removing the plastic inverter terminal covers, loosen the screws at the top and bottom of the terminal covers to remove them. Slide these covers over the leads you'll be using to connect to the inverter.
- Remove the nuts and washers from the inverter terminals.
Diagrams showing the connection of cables to the inverter's terminals. One diagram shows a red positive cable eyelet being attached with a nut and washer to the positive terminal. Another shows a black negative cable eyelet attached similarly to the negative terminal.
- Attach the positive and negative cable to their respective input terminal. Thread the cable eye and washer over the bolt, then secure it with a nut to ensure a tight connection, repeat this step for both sides.
- Reinstall the inverter terminal covers.
- Connect the positive and negative inverter cables to the battery or DC power source. First, attach the positive terminal, followed by the negative terminal.
Ensure the positive lead has an appropriately sized and placed fuse for added safety.

Remote Installation (Sold Separately)
The remote allows the inverter to be operated from a distance, making it perfect for installations where the inverter is not easily accessible.
- Select a space you would like the inverter remote to be installed, preferably away from moisture in a canopy or caravan wall.
- Refer to the mounting diagram below for the dimensions of the hole you will have to make.
- Drill 2mm holes on the designated mounting points and cut a hole in the mounting surface according the diagram above.

- Remove the faceplate of the inverter remote by pulling on the small recess along one of the outer edges.
- Insert the remote into the prepared hole and secure it in place using M3 screws to ensure a secure fitment.
- Reattach the inverter remote faceplate and connect the included RJ12 cable to the core.
Mounting Requirements
When mounting the inverter, please adhere to the following guidelines:
VENTILATION: Provide at least a 100mm space around the inverter to prevent heat build up.
Diagrams illustrating correct inverter mounting orientations: horizontally on a flat surface (ideal, marked with ✔️), vertically (acceptable, marked with ✔️), and not upside down (marked with ❌).
ORIENTATION: Ideally, mount the inverter horizontally on a flat surface. Vertical mounting is ok however this may put stress on the circuit board. Do not mount the inverter upside down (with the base facing up).
STABLE: Ensure the inverter is mounted on a sturdy surface capable of supporting its weight, utilising all of the mounting points with the correct fasteners.
DRY: Mount the inverter in an area free from moisture.
COOL: Opt for a mounting location that stays within 0°C and 40°C.
SAFE: Ensure the mounting area is free from fumes and other potential hazards.
LIMIT DUST: Mount the inverter in an area with minimal dust ingress to prevent dust from being drawn in by the fans during operation.
ELECTRICAL: Position the inverter close to the battery to minimise voltage drop. Maintain a distance of at least 300mm between the inverter and the battery. Install a fuse on the positive cable between the inverter and the battery, placing the fuse close to the battery end to protect the cable.
Cable & Fuse Guide
The cable between the inverter and battery must be thick enough to prevent voltage drop. Since voltage drop happens between the battery positive and ground, the total length of both cables must be considered.
NOTE: The cables should be routed in a way that reduces the risk of damage. Consider using cable conduit or protective tubing to mitigate this risk.

Battery Preparation
Before installing your inverter, it is essential to verify your batteries are 12V and are one of the following chemistries: SLD, AGM, GEL, or LiFeP04. The inverters are also capable of being connected to batteries in parallel. Paralleling an iTechworld battery with a compatible iTechworld battery of the same Ah and type will increase the maximum continuous discharge rate.

Operation
OPERATING THE INVERTER:
Once you've wired the input side, your inverter is ready to power your 240V appliances. Before operating the inverter, ensure the total wattage of the appliance/s you intend to use is below the rated wattage of the inverter.
- If you're powering the inverter from a 12V source, ensure that the battery has enough charge to support the draw.
- Plug the appliance into the AC 240V output.
- Turn on the inverter.
- Turn on your appliance/s.

AC 240V OUTPUT OVERVIEW:
Each inverter is equipped with standard Type I AC 240V socket/s for appliances. You have the option to directly plug the appliance into the inverter or use a power board to power multiple appliances simultaneously.
It is important to note you can only connect appliances with a wattage the same or below the rated max of the specific inverter. For instance, an iTechworld 3000W inverter has a maximum continuous output of 3000W. So you will have to ensure the combined wattage of all the connected devices does not exceed 3000W.
