Power Inverters

Power inverters convert 12V DC power from your renewable energy source into 240V AC power that is needed for running appliances, such as hair dryers, televisions and more.
Power inverters are an ideal source of portable mains power. Being compact and portable, power inverters can be used in cars, caravans, boats, 4WDs and trucks. Using a power inverter for household appliances is a much cheaper option than purchasing specialized 12V appliances for those times when mains power is not available. Compared to generators, power inverters are a greener and cheaper long term option.
Inverters are grouped in two major categories: those designed to convert solar energy directly into AC without the use of storage batteries (grid interactive or grid tie inverter) and those designed to provide power from batteries, with the batteries being charged by any number of sources (stand-alone or off-grid inverters).
Among the stand-alone inverters, there are modified sine wave/square wave inverters and pure sine wave inverters. Modified sine wave inverters are cheaper than pure sine wave inverters and do not represent true AC power that you would normally acquire from the utility power delivered to your home. Pure sine wave inverters produce the same grade of power that you would normally receive from the utility grid in your home. Both styles of inverters can operate all sorts of AC equipment, however items such as microwave ovens, bread makers or any sensitive equipment that is controlled by a digital clock will only run of a true sine wave inverter.
Inverter chargers combine an inverter and a battery charger in one complete unit, providing reliable alternate AC power during utility power problems, such as blackouts, brownouts, overvoltages and surges. When utility power is present, inverter chargers automatically pass through power to your equipment while simultaneously recharging your connected batteries.

Being able to correctly choose the right size inverter for your need is an important consideration. To determine the power requirement to run your appliances use this calculation:
Volts x Amps = Watts
An example of this would be a small microwave that according to the back panel could draw 5.5 amps to operate effectively would require an inverter of at least 1320 watts (240 x 5.5 = 1320).

iSustain Australia offers a wide range of Inverters to meet your specific application. When choosing an Inverter you should consider the following:
1. The total wattage of connected devices should not exceed the model's continuous wattage rating.
2. The number of connected items of equipment to determine how many outlets are required.
3. The application to help you choose the proper type of inverter or inverter/charger.
