Best Power Inverters 2019

Power Inverter

Power Inverters are electrical devices which converts DC Power into AC power so that we are able to run common appliances like refrigerators, lights, fans etc in our homes, offices and so on.  But the real question is why there is a need to covert Direct Current to an alternating Current? The answer to this question is very simple. Today’s almost all electrical appliances use in our home, industry, markets etc run on AC Power. Inverters can be used to produce electricity during emergency situation when there are black outs of commercial energy and when you are enjoying outdoor with your family on holidays. Inverters use in our daily life can be divided into two main categories i.e Conventional inverters and Solar inverters.  Conventional inverters convert DC power from Battery while solar inverters convert DC power from battery as well as from solar panels. Most common sources of DC powers are Batteries and Solar panels. In this article we will look into both type inverters. Further there are two main types of solar inverters i.e. Off grid Invertor and On grid Inverter (Grid Tie). Grid Tie inverters are those which supply extra energy to yours local utility company and save or earn money for you while Off-grid inverters could not supply energy to yours local utility company. Pure sine wave inverters are more expensive than modified sine waves.

Optimal Use and Precautions

  • Do not apply DC 24V for DC 12V Inverters.
  • Always turn off inverter when not in use otherwise it might discharge the battery.
  • The modified sine wave inverters work fines for resistive products but does not work good for inductive products. If you need to use for appliance using a motor or a delicate piece of medical equipment, you need a pure sine wave inverter.
  • Not all inverter can be used as a UPS.
  • Always read device specifications specially operating voltage Wattage before connecting to inverters.
  • It is always recommended to use inverters upto their 80% load for their long life and optimum efficiency. It means if you have 1000 watts inverter then you should not put load more than 800 watts.
  • Do not use more than 80% load of electrical appliances for a long time, it can prevent the damage of inverter
