Inverter Applications
The Xanbus system performs differently depending on the AC loads connected to it. If you are having problems with any of your loads, read this section. The Xanbus system perform differently based on different loads.
Resistive Loads
These are the loads that the inverter finds the simplest and most efficient to drive. Voltage and current are in phase, which means they are in step with one another. Resistive loads usually generate heat in order to accomplish their tasks. Toasters, coffee pots, and incandescent lights are typical resistive loads. It is usually impractical to run larger resistive
Motor Loads
Induction motors (motors without brushes) require two to six times their running current on start up. The most demanding are those that start under load (for example, compressors and pumps). Of the capacitor start motors (typical in drill presses, band saws for example), the largest you can expect to run is ½ to 1 hp (the 30 amp transfer relay is rated at 1 ½ hp). Universal motors are generally easier to start. Since motor characteristics vary, only testing will determine whether a specific load can be started and how long it can be run.
If a motor fails to start within a few seconds or loses power after running for a time, it should be turned off. When the inverter attempts to start a load that is greater than it can handle, the inverter will turn itself off after a few seconds.
Problem Loads
Very small loads
If the power consumed by a device is less than the threshold of the Load Sense mode circuitry, and load sense is enabled, the inverter will not run. Most likely the solution will be to defeat the Load Sense mode feature or lower the sense threshold. Refer to Xantrex Tech Note TN3
