Technical Description
14.1.2 Generator Start Options
The Sunny Island supports the following options for starting the generator which can be set in standby
mode with the ”234.07 GnStrMod” parameter:
• Manual
• Autostart
Manual (Manual Generator Start)
This setting is for generators that do not have an electrical remote starting option and, for example,
are started using cable winches or cranks, or similarly.
In this case, the Sunny Island does not have the option of starting the generator. It only monitors the
generator input (AC2). If, while monitoring the input, the device detects that the generator voltage
and frequency are within the set limits (see 14.1.6 ”Limits and Power Adjustment” (page 122)), the
device is synchronized and connected following the warm-up time.
The following figure shows the wiring for a generator that cannot be started remotely:
The generator is also always switched off manually. The Sunny Island then automatically switches to
operation without generator.
Cable Length and Cable Cross-section
Use the same cable lengths and cable cross-sections when installing the Sunny Island
inverters with the generator.
