8 Commissioning
8.1 Preparation
For commissioning the system you require information on:
• the battery type
• the nominal capacity (C10),
• the generator type,
• the maximum output current that the generator can cope with.
To ensure that these values are available when first commissioning (see section 8.2
"Initialization" (Page 66)), you can note these values here:
Battery type: _____________ sealed battery (Gel/Absorbed Glass Mat (VRLA))
or sealed battery (liquid electrolyte (FLA))
Battery capacity**: ________ Ah (100 to 6,000)
**The Sunny Island 3324/4248 assumes a C10 value for the capacity (factory setting is 100 Ah).
The battery capacity is to be entered as the nominal capacity for a ten hour discharge
(C10). If this is not available from the battery manufacturer's data sheet, then
calculate this from the data for different discharge times (120 h, 100 h, 20 h, 5 h,
1 h) in the following manner:
Battery charging current: __________ A (100)
If the battery manufacturer recommends a maximum charging current then set this
value ("23-4 AmpdcBatMax" parameter). This value often lies around 10–20 A for
each 100 Ah nominal capacity. If the manufacturer does not specify a maximum
charging current then set the maximum possible charging current at 100 A. The
setting of the charging current is described in point 14 of section 8.2 "Initialization"
(Page 66).
Before beginning, ensure that all electrical connections have the correct
polarity and make sure that everything is connected according to the
instructions in section 5 "Electrical Connection" (Page 31).
