48 Volt Inverter 
                          Chargers
                         Inverter chargers combine 
                          an inverter and a battery charger 
                          in one complete unit. They can be used with a solar 
                          PV array or wind turbine power 
                          system or when another there is another AC power source 
                          available, such as a diesel generator or utility power. 
                          They can operate as uninterruptible power supplies (UPS). 
                          These intelligent devices can behave either as an inverter 
                          or a charger and can switch between one and other as 
                          required. Inverter chargers can be connected to the 
                          electricity grid, but they are not grid tied inverters.

                        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.
