Modified Sine Wave Inverters – 12V & 24V DC to 240V AC
Shop our range of modified sine wave inverters at ausElectronicsDirect. Designed to convert 12V or 24V DC battery power into 240V AC mains electricity, modified sine wave inverters provide a practical and economical solution for powering compatible electrical appliances when mains power is unavailable.
Whether you need a compact inverter for your vehicle, a portable power solution for camping or an inverter for an auxiliary battery system, we offer a selection of modified sine wave power inverters in different wattage ratings. Choose from various models, including compact 150W inverters through to higher-capacity 1500W models.
What Is a Modified Sine Wave Inverter?
A modified sine wave inverter is an electronic device that converts direct current (DC) electricity from a battery into alternating current (AC) electricity.
Unlike pure sine wave inverters, which produce a smooth AC waveform, modified sine wave inverters produce a stepped waveform that approximates the alternating current supplied by mains electricity.
They provide an economical option for operating many compatible electrical appliances, including selected laptop chargers, phone chargers, stereos and other low-wattage mains-powered equipment.
What Is the Difference Between Modified and Pure Sine Wave Inverters?
The main difference between modified and pure sine wave inverters is their AC output waveform.
A pure sine wave inverter produces a smooth waveform similar to standard mains electricity, while a modified sine wave inverter produces a stepped waveform.
Modified sine wave inverters are generally more affordable and suitable for many basic electrical applications. Pure sine wave inverters are recommended for sensitive electronic equipment, certain appliances with motors and devices that require a cleaner AC power supply.
Always check the electrical requirements of your appliances before choosing an inverter.
Choosing the Right Modified Sine Wave Inverter
When selecting an inverter, consider the battery voltage, appliance power consumption and the inverter's continuous and peak power ratings.

FAQ
1. What is a modified sine wave inverter?
A modified sine wave inverter converts DC electricity from a battery into AC electricity using a stepped waveform. It provides an economical way to power many compatible electrical appliances when mains electricity is unavailable.
2. What is the difference between a modified sine wave and pure sine wave inverter?
A modified sine wave inverter produces a stepped AC waveform, whereas a pure sine wave inverter produces a smooth waveform similar to standard mains electricity. Pure sine wave inverters offer broader compatibility with sensitive electronic devices and appliances that require a clean AC supply.
3. What can you run on a modified sine wave inverter?
Modified sine wave inverters can operate many compatible electrical devices, including selected phone chargers, laptop power supplies, stereos and low-wattage appliances. However, some electronic devices, appliances with motors and equipment with sensitive power supplies may not operate correctly.
4. Can a modified sine wave inverter charge a laptop?
Some laptop power adapters are compatible with modified sine wave inverters, but compatibility is not guaranteed. Check the laptop charger's specifications or manufacturer recommendations before connecting it. A pure sine wave inverter is generally the safer choice where compatibility is uncertain.
5. Can I use a modified sine wave inverter for camping?
Yes. Modified sine wave inverters can be used for camping to provide 240V AC power from a compatible 12V or 24V battery system. They are suitable for selected chargers and other compatible appliances. Check the power requirements of your equipment before use.
6. What size modified sine wave inverter do I need?
The correct inverter size depends on the combined running wattage of the appliances you want to operate. You should also account for starting surges from appliances with motors and ensure the battery system can supply the required current.
7. What is the difference between a 12V and 24V inverter?
A 12V inverter operates from a compatible 12V DC battery system, while a 24V inverter requires a 24V DC battery system. A 24V inverter generally draws less current than a 12V inverter when delivering the same AC output power.
8. Can a modified sine wave inverter run a refrigerator?
Some refrigerators may operate with a modified sine wave inverter, but compatibility depends on the refrigerator's compressor and electrical design. Compressor starting current can also be considerably higher than normal running current. A suitably rated pure sine wave inverter is generally recommended for refrigerators.
9. Can I use a modified sine wave inverter with a solar battery?
Yes. A modified sine wave inverter can operate from a compatible solar-charged battery system. The battery voltage must match the inverter's DC input requirements, and the battery must be capable of supplying the necessary current.
10. Are modified sine wave inverters safe to use?
Modified sine wave inverters can be used safely when installed and operated according to their manufacturer's instructions. Choose an inverter with appropriate electrical protection, use correctly rated cables and fuses, provide adequate ventilation and avoid exceeding its rated power output.
