| Inverters change direct current (DC) to alternating current (DC). Inverters are used to convert DC from a battery or renewable energy source to AC to run electronic equipment, lighting, villas, resorts and hotels, etc. There are several types of inverters used in the renewable energy industry. Synchronous Inverters can be used to convert the DC output of a batteries, photovoltaic module, a wind generator or hydro generators to AC power to be connected to the utility grid, PLN. Multifunction inverters perform both functions. |
Stand-Alone Inverters |
|
| Stand-Alone inverters convert DC power stored in batteries to AC power that can be used as needed. Selecting an inverter for your power system based on the maximum load you will be powering, the maximum surge required, output voltage required, input battery voltage and optional features needed. |  |
| Stand-alone inverters are available with three basic power output waveforms: square wave, modified square wave (sometimes called modified sine wave) and pure sine wave. Synchronous Inverters and Utility companies deliver a pure sine wave. High quality stand-alone inverters are available in sizes from 100 watts, for powering notebook computers and fax machines from your car, to 8000 watts, for powering an entire house or small commercial operation. The size of an inverter is measured by its maximum continuous output in watts. This rating must be larger than the total wattage of all of the AC loads you plan to run at one time.
The size of the inverter can be minimized if the number and size of the AC loads is kept under control. Wattage of most AC loads can be determined from a tag or label on the appliance, usually located near where the power cord enters, or from the owner's manual. If the inverter is expected to run induction motors, like the ones found in automatic washers, air-conditioning, dishwashers and large power tools, it must be designed to surge, or deliver power many times its rating for short periods of time while these motors start. Sinewave inverters, available in sizes from 150 watts to 2000 watts, are an excellent choice for power systems running audio equipment and other electronics that are waveform-sensitive. Larger Sinewave inverters are available in sizes up to 200,000 watts, that can run a small village. |

Synchronous Inverters |
|
| Synchronous inverters change DC power from renewable energy source into AC power to be directed into the utility grid. A power system with this type of inverter uses the utility company as a storage battery. For example, when the sun is shining, your electricity comes from the solar array, via the inverter. If the solar array is making more power than you are using, the excess is fed to the utility grid.
|
 |
| If you use more power than the solar array can supply, the utility makes up the difference. This type of system makes the most sense if you have utility power, because there are no batteries to maintain or replace. Using a multifunction inverter allows you to sell excess power to the utility, and also maintain a battery bank for stand-by power in the event of a utility power failure. | |
Multi Function Inverters |
|
| Multi Function inverters are a combination of both a Sinewave and Synchronous Inverters. They allow you to feed excess power to the utility and also maintain a battery bank for stand-by power in the event of a utility power failure. these types of inverts are becoming more the standard within the renewable energy industry. | |
