Generator Operation - SMA Sunny Island 5048 Installation Instructions Manual

Connecting External Sources
The following figure principally displays the generator start using the "GenMan"
generator controller.
The GENRDY signal sends a manual generator start at the GenMan to the Sunny Island
5048. The device synchronizes and connects.
If the generator is externally and manually started at the GenMan, Sunny Island 5048
blocks the GnReq signal:
• Manual stop and start are ignored on the Sunny Island 5048 (operated using the
display and keyboard).
• Internal requests (e.g. via the battery charge state) are also ignored.
If the generator has been manually started at the GenMan, it must also be
stopped there.
The Sunny Island 5048 disconnects the generator if the GenMan has disabled the
GENRDY signal.
A manual start directly at the generator is not permitted (see GenMan manual).

14.1.2 Generator Operation

The Sunny Island 5048 allows automatic operation (depending on charge state or
load) (see 14.1.4 "Automatic Generator Operation" (Page 101)). In addition, manual
operation is also possible.
