10.2.2 Generator Start with a Single Contact (2-Wire)
An autostart generator requiring a single contact (see section "2. "Direct" Setting"
(Page 76)) is directly connected to the Sunny Island 3324/4248. The wiring is shown
in the following figure:
The following parameters must be set:
40-8 SunnyBoys Yes Set this parameter only to Yes when Sunny
Boy inverters are connected to the system.
