Health & Safety Guidelines
IMPORTANT: This inverter is only suitable for use with 12V batteries only.
Warning! Electric Hazard. Keep away from children
1. This inverter is not a toy, and it should never be used by children.
2. This inverter generates the same voltage as a UK 3-pin plug socket.
Please operate it as if you are using any other AC mains socket.
3. Never insert any kind of foreign object into the inverter’s plug sockets,
fan or vent openings.
4. Do operate or expose the inverter to water, rain, snow or spray
5. Never connect the inverter to an AC power source. This inverter is only
designed to accept a DC power supply.
Warning! Heated Surface
6. The inverter’s outer casing may become hot after prolonged use or
overloading. During operation, ensure there is atleast a 5cm (2 inches)
gap between the inverter and any other walls.
7. Please keep any flammable materials away from the inverter during
operation.
Warning! Explosion Hazard
8. Never use the inverter in the presence of flammable substances
Caution!
9. Do not connect a live AC power source to the inverter’s AC output
sockets. This will damage the inverter, even if the inverter is switched
off.
10. Do not expose the inverter to temperatures over 40°C.
Caution! Do not use the inverter with the following equipment:
11. Appliances that have a AC motor. This includes refridgerators, heavy
duty power tools, washing machines, dishwashers and medical
equipment.
12. Devices that have a thyristors. This includes laser printers and
photocopiers.
13. Large electrical appliances such as newer electrical TVs with LED
display.
14. Flourescent lights.

Intention For Use
Thank you for purchasing this 3000W modified sine wave inverter from Streetwize.
This inverter safely converts your vehicle’s 12V DC battery into a 240V AC power
supply for using standard UK electrical appliances that require up to 3000W.
It is intended for people who require access to an AC power supply in areas where
there is restricted access to power. They’re suitable for caravan/campervan users as
well as tradespeople.
This modified sine wave inverter is not suitable for use with appliances with AC
motors (i.e. microwaves, refrigerator), medical equipment, laser printers and
flourescent lights.
IMPORTANT: This inverter is primarily designed for powering appliances up to its stated
continuous output. The stated peak output is only available for a limited time.

Pure Sine Wave & Modified Sine Wave Inverters
There are two types of inverters: Pure Sine Wave & Modified Sine Wave.
The figure below shows a graphical comparison of modified sine wave inverters and pure
sine wave inverters.
Modified sine wave inverters provide a cost-effective option of powering 230V AC
appliances from a 12V battery. However, a pure sine wave inverters provide even flow of
electric output where a modified sine wave inverter is staggered.

sine wave inverters.

Operating Instructions
Optimum Working Conditions
For safe & optimum performance, please install the inverter in a location that is:
• Dry - The inverter should not be near any liquid or moisture.
• Cool - Keep it away from any high heat source.
• Well-ventilated - Allow for atleast 5cm of space on all sides.
• Clean - To prevent any dust or unwanted elements from getting inside the inverter.
• Away from flammable substances - To prevent fire or explosion.

12V Socket
To use the inverter via your vehicle’s 12V socket, simply connect the O-rings of the 12V
connection cable to the inverter’s terminals, with the black cable going to the negative
terminal and the red cable going to the positive terminal. Plug the 12V plug into the 12V
socket, then switch on your vehicle.
WARNING: Only use the 12V plug for powering appliances that require less than 150W.
Do NOT power an appliance that requires more than 150W as this will risk damaging your
vehicle’s fuse.
Direct Battery Connection
Before connecting this inverter, please ensure your vehicle is fully switched off.
Then, connect the black (negative) battery clamp connection cable to the negative terminal of the inverter via the O-ring first, and then connect the clamp to the negative battery
terminal of your 12V battery. Then, connect the red (positive) battery clamp connection
cable to the positive terminal of the inverter via the O-ring and then connect the clamp to
the positive battery terminal of your 12V batter y.
IMPORTANT: When starting your vehicle’s engine, please disconnect the inverter first
before starting the engine.
Operating Appliances
Operating an Appliance Through The 3-Pin Plug
Once the inverter is connected to your battery, just plug in your appliance via the 3 pin
socket, and then turn ON the power switch.
Operating an Appliance Via The USB
Once the inverter is connected to your battery, just plug in the device via the USB socket,
and then turn ON the power switch.
Peak Output
This inverter provides a continuous output of 3000W as well as a peak output of 6000W.
Meaning, when you try to power appliances that total more than 3000W, the inverter has
the capability to automatically adjust the wattage up to 6000W.
IMPORTANT: When operating appliances that require more than the specified continuous power wattage, the inverter will operate for a very limited amount of time and it will
automatically shut-down.
For long lasting performance, we recommend that you use this inverter for appliances
requiring less than specified continuous power wattage.

After Use
After you have finished using the inverter (or when the inverter is not in use), turn off the unit and
make sure your vehicle’s fully switched off.
Then, turn the unit off and then disconnect the inverter from the 12V power supply. When disconnecting from the battery, disconnect the negative cable first, followed by the positive cable.
Best Practices for Protecting Your 12V Battery
• To prevent your vehicle’s 12V battery from being depleted. We recommend running the engine for 10 to
20 minute to recharge the battery after using the inverter for 2 to 3 hours. Important: Before starting your
vehicle’s engine, please disconnect the inverter from your battery/power supply.
• When connecting the inverter to your battery’s terminals, it is important that you connect it via the correct
polarity (i.e. Connect + from inverter to + of battery terminal and connect – from inverter to – of battery
terminal) to prevent reverse polarity.
• When you are using the inverter and you hear a beeping sound coming from the inverter, this means your 12V
battery is low. To recharge, disconnect the inverter from your battery and turn on the engine for 2 to 3 hours.
• When charging your 12V battery using a battery charger, please disconnect the inverter.
Measuring The AC Voltage
The output waveform of the AC output is a MODIFIED SINE WAVE. To measure the AC
output voltage, you must have a TRUE RMS VOLTMETER.
Safety Features
FeatureExplanation
Anodized Aluminium CasingPrevents corrosion & wear. The case effectively
protects the inverter’s interior elements.
Low Battery AlarmSounds when your 12V battery is low. To
resolve, disconnect the inverter from battery/
power supply and recharge the battery.
Built-in Cooling FanThe built-in cooling helps to prevent overheating
during use.
Overheat ProtectionAfter prolonged use (more than 2 to 3 hours),
the inverter will generate heat. This is not a
malfunction of the built-in cooling fan. However,
if the inverter does overheat, after prolonged
use, the unit will automatically shut off for it to
cool down.

How to Replace the Fuse
Fi g. 1
If the unit stops working, and you see a red LED light and/or you hear an audible beeping.
Then you will need to check to see if any of the fuses are working, and replace any blown
fuses if necessary.
PLEASE NOTE: In total, there are 12 x 30 Amp fuses.
To check & replace the fuse, please follow the instructions below:
1. Loosen and remove the screws on the base of the unit, remove the base plate to
reveal the inside of the inverter.
2. Locate the fuses as shown in the figure below. Use a suitable pair of tweezers to take
the fuse out so you can check/replace as necessary. Please note, you can check the
fuse size when you take out the fuse.
