The following parameters must be set:
Other parameters can also be changed for this system. You will find a list of these
parameters in section 17.2.2 "Adjustable System Parameters" (Page 134).
No. Parameter Parameter value/unit Parameter description
23-2 BatType
(see section 11.4) refer to the data sheet
provided by the battery
manufacturer The type of battery used in the system. To be
set when first commissioning the system (see
section 8.2 "Initialization" (Page 66)).
23-3 AmpHoursBat
(see section 11.4) refer to the data sheet
provided by the battery
manufacturer Battery capacity. To be set when first
commissioning the system (see section 8.2
"Initialization" (Page 66)).
23-4 AmpdcBatMax
(see section 11.4) refer to the data sheet
provided by the battery
manufacturer Max. battery charging current. To be set
when first commissioning the system (see
section 8.2 "Initialization" (Page 66)).
24-2 AmpacGenMax 0.85 * nominal generator
current (see generator
datasheet) Max. generator output current (see section
8.5.2 "Setting the Output Current Limit"
(Page 77)).
40-2 Autostart On The Sunny Island 3324/4248 can restart
automatically.
40-6 LoadShedding Auto Automatic control of the load shedding relay
by the Sunny Island 3324/4248
40-8 SunnyBoys Yes Set this parameter to Yes when Sunny Boy
inverters are connected to the system.
Load shedding is an important feature for protecting batteries from quick
aging caused by deep discharge. This is only activated when, over a longer
period of time, more energy is consumed than is generated, or when the
generator does not start (lack of fuel, generator fault).
