Renewable Energy Systems with Optional Generator Backup

8
In the event that renewable energy sources are insufficient to power the required
loads or keep the batteries charged, a generator can be used to supplement the
system. The SB Option is required on the inverter for this application. The SB
Option provides a pass-through relay that allows power from the generator to
pass through the inverter to either support the AC loads and/or charge the
batteries.
See Figure 2-2 for an illustration of a renewable energy application with the
SB Option installed on the UX Inverter.
This illustration includes the optional generator backup as well as illustrates
the utilization of the optional accessories such as remote monitoring options
and a variety of renewable energy sources. Disregard any part of this
illustration that does not apply to the system configuration being installed.
See page 20 for additional information regarding generator configurations.
