Inverters are designed to manage the flow of electricity into and out of the batteries to provide an automatic supply of utility grade AC electricity for loads such as household appliances. Three factors for consideration when choosing an inverter are:

• Input Vdc - the inverter DC input voltage must match the battery bank voltage;

• Continuous Power - the maximum continuous load run by the inverter;

• Surge current – some loads, such as electric motors, demand more power when they start. All inverters consume energy (tare loss). To counteract tare loss, most inverters offer a sleep mode or low power mode to save energy consumption. Ask your SunWize dealer for more information.

Pure Sine Wave Inverters

Depending on the model, the AC output of an inverter is either a modified or pure sine wave. Modified sine wave power is suitable for some loads but not for electronics such as home theater systems, high-end televisions and computers. Pure sine wave output is ideal for sensitive electrical devices due to the low electromagnetic interference level. All inverters in this section produce 120 Vac, 60 Hz. Some of the inverters may be stacked to power 240 Vac loads or a 120/240 transformer can be used to power 240 Vac loads from a single 120 Vac inverter. Modified sine wave inverters will be discussed in the next section.
