10.2.1 Generators with Manual Start
A generator without an autostart feature must be started manually, i.e. by hand (see
section 8.5.3 "Generator Request" (Page 77)). A light can be connected to the
system to inform the user that the batteries have reached a critical state (see "12-4
BatState" parameter and section 11.3 "Deep Discharge Protection/Battery State"
(Page 105)) and must be charged. The following figure shows the wiring between
the generator and the Sunny Island 3324/4248:
The following parameters must be set:
The following subsections (10.2.1 to 10.2.4) show you a range of possible
ways how the generator connected to your system can be started.
