Types of Power Inverter

Your choice of best power inverter for cars must not be limited to brand, features, or cost. You must also give consideration to the type of the device. In every category of inverter, there is a different system being used to convert electricity.

  • Modified Sine Wave Inverter – This is a type of inverter used at home that accumulates electricity of 12 volts. It requires charging using a solar panel or generator. This inverter could make light bulbs, microwave ovens, and fans work.

For homes, this is a considerable inverter to use since it is portable and efficient enough. Compared with others, modified sine wave inverter is also the cheapest. However, it is not advised to be used in appliances with motor speed settings.

  • Square Wave Inverter – This is among simplest inverter types available. It transforms a direct current signal to a phase conversion alternating current signal. It is a cheaper inverter as well.

You would find this inverter in a very straightforward construction with switches for on and off. The basic setting is prior a normal voltage ramping transformer-like circuit.

  • True Sine Wave Inverter – By quality, this is a more effective type of inverter. It utilizes better electricity source for homes. Moreover, true sine wave inverter may operate using a larger capacity battery.

The efficiency of the inverter is defined by how pure its sine waves are. It could be used for washing machines, refrigerators, air conditioners, and televisions. Although the inverter is a bit pricey, it is highly reliable for families.

It has a more complex structure than modified sine wave inverter. It has several advantages over the first type of inverter, such as consumption of less power. It could also be tweaked based on your power requirements.

Pure sine wave inverter also has more efficient and reliable output. It is the best inverter in making most sensitive equipment work.

  • Solar Inverter – This is the type of inverter most known to man. It is energy-efficient and does not require a different power source. It is useful for homes and has different types. Solar inverters could be stand-alone, grid tie, or battery back-up.

Stand-alone solar inverter is normally used in charging cell phones, car battery, laptops, and water pumps. It is useful when there is no local power grid present. Basically, its collected energy is contained in rechargeable batteries.

Grid tie inverter is used when local power grid is present and linked to a solar array. You would find this inverter in urban places. It does not require batteries, making it cheaper.

Battery backup solar inverter is also called dual inverter. It performs multiple functions, which collectively send solar panel-generated direct current signals to battery. It is more expensive, but it could maximize production of energy.

The benefits of solar inverter include easy installation due to its straightforward construction. Compared with other inverter types, it is highly efficient. Solar inverters are also cooled by convection, which means it will not require special fans for cooling.

What to Look For When Buying

There are aspects to consider if you will look for the best car power inverter. You cannot settle for the brand or cost alone. To find the device that suits your needs perfectly, here are things to consider:

  • Determine Your Power Requirements – You need to have a rough estimation of how much energy you need from your chosen best car inverter. Calculation of your appliances’ power consumption must be done. Generally, you must have a device that could produce 50 percent more than what you need, which means there is an allowance.
  • Always Use Protected Wire – Charging your appliances or gadgets using an inverter must always be done with a rubber-insulated wire. Basically, you do not have to worry about this since most packages come with cables.
  • Keep Wires Properly – In the case of connecting your inverter to any appliance to power up, ensure that it is far from flammable material. If you have wired the inverter to a car, ensure that even oil residue will not touch the wiring. Moreover, do not forget that an inverter may generate heat when operating.
  • Store Inverter at the Right Place – It is recommended that you keep your inverter in a location that is level to the surface. Guarantee that the surrounding is also dry. Prevent areas where the inverter may slide off and come in contact with wet materials.
  • Find a Voltage Stabilizer – Voltage fluctuations could be detrimental to users of inverters. Modern types of the device now come with a voltage stabilizer. This means that the commercial power supply will be directed with sufficient monitoring.
  • Consider Add-On Features – You may likely get a benefit in having clear indicators of input or output voltages, battery charge rate, or load of power, among others.
  • Do Not Forget the Warranty – Never take for granted the advantage of finding a device with a supplier’s warranty. This gives you the edge to complain or get a replacement if you received a defective product.

Using Safety Tips

Even the top rated power inverter must be used properly in order to maximize the device’s advantages. Not all people are familiar with its careful and appropriate use. As a guideline, here are tips that will help:

  • Hooking Up an Inverter Using a Cable – Most power inverters are packaged with cables, which is why you do not have to be concerned on the wiring to use. There are small inverters that come with cigarette lighter adapter. Despite its lower watt accumulation, it could be plugged into the lighter socket of your vehicle.

Alternatively, larger inverters are normally hooked into a battery using hard wires. The size of the wire will be based on inverter and battery distance. The manual of the inverter may specify this.

During the connection of inverter and battery, a protection device must always be used. A circuit breaker or fuse could be used. Always choose a practically sufficient and thickest wire possible.

  • Check an Appliance Operating Power Always – The operating power of appliance is not always the advertised rating on its label. For instance, a microwave may have a rating of 600 watts, but in actual, it consumes up to 1,100 watts of energy. The best thing you could do is check the manual of the appliance beforehand.
  • Danger in Powering Up Cordless Power Tools – You should not plug in the inverter’s battery to cordless power tools, which provide a warning of battery terminal in which hazardous voltages are present.
  • Powering Bulbs With Inverter – You should not consider all bulbs to work using an inverter. You have to stop using an inverter to a lamp when it does not turn on or emits too bright illumination.
  • Using Inverter With Fans – You should not worry if your electric fans operate too fast when powered by an inverter, specifically by a modified sine wave type. This is anticipated and will not bring harm to either of the devices.
  • Storing Inverter Properly – Placement of an inverter must be done with care since it carries as much as 110 volts, which is already a lethal energy amount. Consider selecting a flat surface for its storage. Find an area that will maintain the device’s cool and dry condition.
  • Keep the Inverter Protected – Never operate an inverter when there is moisture or rain exposure. Serious accidents or death may result when electricity comes in contact with water.
  • Ventilation Is Necessary – When operating an inverter, keep the area with sufficient air circulation. The location where the inverter is placed must have clearance on the sides and top.
