Inverter Applications

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 (e.g. compressors and pumps). Of the capacitor start motors (typical in drill presses, band saws, etc.), the largest you can expect to run is 1/2 to 1 hp (the transfer relays are rated at 2 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, it will turn itself off after a few seconds.

Long Transfer Times

Xantrex has observed a specific situation where the Freedom HF may take a long time to transfer to inverter mode when shore power fails - maybe 0.1-0.2 seconds. This can occur when the Freedom HF is power motor loads where the motor is able to freewheel when power is removed (e.g. a grinder). This long transfer may cause computers or other sensitive equipment to operate incorrectly. If power glitches must be minimized then Xantrex recommends that motor loads not be operated when sensitive equipment is being used.
