DC AC power inverter
So, the problem arises when you need to take power that has been stored in a battery or bank of batteries, and use it to run electrical appliances that are AC and not DC.
The answer to this, is to use a DC to AC power inverter.
The inverter is the main component of any independent power system which requires AC power. The power inverter will convert the DC power stored in the batteries and into Ac power to run conventional appliances.
Inverters
Just over a decade or so ago, DC AC power inverters were so inefficient and unreliable, many people restricted themselves to 12V lights and appliances.
If you have recently tried to shop around for 12V DC appliances, you will see that there is a very limited selection available.
Today, the efficiency and reliability of the latest DC AC power Inverters, are a far cry from the inverters that were available 15 to 20 years ago.
There are three waveforms produced by modern solid state power inverters. The simplest, a square wave power inverter, used to be all that was available. Today, these are very rare, as many appliances will not operate on a square wave.
