Utility Backup with a Generator

16
The UX inverter can be used with an AC Transfer switch to allow a generator to
provide backup power in the event that the utility grid fails. When the utility grid
fails, the inverter switches the loads over to the battery-bank. If the utility failure
is prolonged and the batteries become discharged, the generator must be started
to support the loads and recharge the batteries.
See Figure 2-6 for an illustration of a basic utility backup configuration.
This illustration includes the optional accessories such as the RC8 Remote
Control and the Battery Temperature Sensor. Disregard any part of this
illustration that does not apply to the system configuration being installed.
