INSTALLATION
AUTOMATIC TRANSFER SWITCH
The ATS function enables the inverter to automatically switch from using 12V to AC 240V. It is beneficial for preserving your batteries and is used in situations where you opt to run your system from a powered site. Once the inverter detects incoming AC 240V current, the ATS function will activate, which will seamlessly switch the inverter input from 12V to AC 240V within 30ms.
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.

AC 240V INPUT INSTALLATION
Before connecting the AC input, ensure you have the following cables on hand.
| AC INPUT CABLE | 2000W PRO | 3000W PRO |
| INPUT END | IEC-C13 | IEC-C19 |
| MAINS END | Type 1 | Type 1 |

Connecting the inverter to AC 240V is straight forward. Simply insert the IEC plug into the inverters AC input, and then insert the 3 – pin plug into an AC 240V socket or power point. The inverter is designed to automatically switch to AC 240V power when available, ensuring smooth operation.
⚠️ We recommend this install is done by a licensed electrician. ⚠️
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.

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 my removing the plastic inverter terminal covers, loosen the screws at on 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 battery terminal connection hardware (nuts, washers, eyelets) and the correct way to attach cables to terminals.
- Attach the positive and negative cable to their respective input terminal. Thread the cable eye and washer over the bold, then secure it with a nut to ensure a tight connection, repeat this step for both sides.
- Re-install 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 showing correct (✔️) and incorrect (❌) mounting for ventilation, with 100mm space indicated.
ORIENTATION
Ideally, mount the inverter horizontally on a flat surface with the base facing downwards. 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 my 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 to ensure
| LENGTH | SIZE (AWG) | |
| 2000W PRO | 3000W PRO | |
| 0-1M | 70mm² (2/0) | 95mm² (3/0) |
| 1-2M | 70mm² (2/0) | 95mm² (3/0) |
| 2-3M | 95mm² (3/0) | 120mm² (4/0) |
| MODEL | 2000W PRO | 3000W PRO |
| FUSE SIZE | 250A | 450A |
BATTERY PREPERATION
Before installing your inverter, it is essential to verify your batteries are 12v and is 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.

| MAX CONSTANT AMP DRAW | 185A | 278A |
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 an 12V source, ensure that the battery has enough charge to support the draw. For AC 240V input, ensure there is a secure connection.
- Verify the RCD is in the correct position, do not proceed if this if it has been tripped - seek assistance from a licensed electrician.
- Plug the appliance into the AC 240V output or IEC 240V socket.
- Turn on the inverter. If you're using AC 240V input, ensure that the mains AC 240V supply is also turned on.
- Turn on your appliance/s.

AC 240V OUTPUT
Each inverter is equipped with standard Type I AC 240V and specialised IEC sockets 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, iTechworld 3000W PRO 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.
