17.2.2 Adjustable System Parameters
Inverter Settings
Battery Settings
Only change parameters marked with (Stby), when the Sunny Island 3324/
4248 is in standby mode. Appropriately set operational data can take effect
as soon as the "Enter" key is pressed. Incorrect values in these parameters can
probably not be corrected quickly enough to avoid potential damage to your
system.
All parameters marked with a (B) can be set while the system is running.
All parameters can be set using a connected PC/laptop with the Sunny Data
Control software, a Sunny WebBox or a Sunny Boy Control (see section 15
"Communication Interface" (Page 123)).

These parameters must be set when first
commissioning the system. After this, the
value can only be changed after you
have set the "23-5 New Battery"
parameter to the value "Reset". The Sunny
Island 3324/4248 will then again run
through the INIT phase (see section 8.2
"Initialization" (Page 66)).
23-3 AmpHoursBat
(see section 11.4) 100 to 6000 Ah 100 Battery capacity. These parameters must
be set when first commissioning the
system. After this, the value can only be
changed after you have set the "23-5
New Battery" parameter to the value
"Reset". The Sunny Island 3324/4248 will
then again run through the INIT phase
(see section 8.2 "Initialization"
(Page 66)).
