1500W 12V PURE SINE WAVE POWER INVERTER by EDECOA

This12v to 240v pure sine wave inverter can provide a continuous supply of power at 1500 watts with a peak of 3000 watts 230 VAC at 50 Hz. To obtain the surge level there must be sufficient power reserves in the 12V battery pack connected by power cables to provide it. This device provides power efficiency at 90%.

To help make this converter quieter than most is the use of silent interior fans to keep it cool which reduces the noise most converters make.

With 1500 watts of continuous power, it can be hooked up to the main electrical board in a caravan, just make sure you do not overload it when turning on appliances. A refrigerator rated at 1500 watts will use 3000 watts at startup.

This pure sine wave inverter has 2 standard UK plug-in receptors and two 2A USB ports that can be used to provide power to the devices you want to use. This device has an LCD display showing the power reserves available to the user.

Safety features include automatic shut offs when overheated above 75C, under and over voltage along with when reverse polarity is detected. There is also an automatic voltage regulator and an intelligent power management system in active mode when the converter is operating. This device has an on/off switch on the unit and a remote control device to kill the power.

300W 12V PURE SINE WAVE INVERTER by BESTEK

This 12v to 240v inverter pure sine wave inverter by Bestek is a 300 watt continuous power supply with a 360 watt max possibility. It is also the easiest to use when needing a small amount of power while you are off the grid. This device has a constant power supply of 300 watts with a peak of 700 watts at 230 VAC at 50 Hz. There is no efficiency rating on this converter.

The converter manufacturer also has a modified sine wave converter that looks the same as this one and rated the same, but the power supply is not the same being a modified sine wave so it can’t be used for all devices.

This small device provides you with options of connecting it to the 12V power source. When 150 watt or less is to be used the cable that connects to what use to be the cigarette lighter socket can be used. The 150 watt limit is due to the 150 watt limited 10A fuse for this socket that is standard in the motor vehicle industry. If more power is needed cables can be used to directly connect it to the vehicle’s battery. These battery cables will have to be purchased separately.

This device has one standard UK plug-in receptor and two 4.8A USB port that can be used to provide power to the devices you want to use. This device has an indicator light showing the power reserves, green for power, red for no power.

Safety features include automatic shut offs when overheated or under and overvoltage is detected. This device has an on/off switch on the unit to kill the power. It does have a small internal fan, but it will still get warm to the touch. Avoid placing it next to warm objects or on the dash where the sunlight might heat it further.

This will help to avert a short circuit or overload. There is one on/off switch on the converter so activating it or deactivating it is simple and a remote device to start and stop it is also provided.

To use the 12v to 240v inverter all that is required is to connect it to a charged battery pack and turn it on. Because this converter is at the upper end of possible power it can supply, it is one of the more expensive to purchase.

1000W 12V PURE SINCE WAVE INVERTER by PHOTONIC

As the name suggests this pure sine wave inverter can provide 1000 watts of continuous smooth power of 230 VAC at 50 Hz. It has a surge peak of 2000 watts when there is sufficient power in the 12V battery pack connected by power cables. This is similar to the first device listed, but is half the power at near half the cost. This device provides power efficiency at 90%.

With only 1000 watts of power, the number of devices that can be powered up at one time will be limited. Fans 100W, TVs up to 200W, satellite TV receiver 30W, laptops 50W, desktops 400W, Mobile phone chargers 5W can be plugged in just do not exceed the 1000W limit.

This pure sine wave inverter has 2 standard UK plug-in receptors and one 2A USB port that can be used to provide power to the devices you want to use. There is no display showing the power reserves.

The safety features on this pure sine wave inverter are the same as it more powerful cousin from above including both low power and high power automatic shut-offs and alarms. There is also a high temperature shut off at 60C so the converter will not become overheated. This will help to prevent a short circuit or overload. There is also one on/off switch on the12v to 240v pure sine wave inverter, so activating it or deactivating it is simple and a remote device to start and stop it.
