As soon as you have entered the password correctly all settings and val-
ues acquired adaptively up to this point are overwritten with standard va-
lues!
After you have entered the password you will reach a menu where you have to set
up essential parameters for the battery, the connected generator and the type of is-
land grid to ensure proper operation.
Parameter Default Description
501_Cbatnom
350 Ah
Nominal capacity of the battery of 10 hours. This always has to
be entered as defined in the manufacturer’s instructions even if
the battery has already aged!
In case the manufacturer did not specify a capacity of 10 hours
select the specification that is nearest to the capacity of 10 hours.
502_Bat Type
Lead acid
Lead-acid battery with...
Lead acid:
... liquid electrolyte
Fleece:
... electrolyte bound in fleece
Gel:
... electrolyte bound in gel
503_Ubat nom
60.0 V
Nominal battery voltage. Normally 60 V have to be set. For ex-
ceptions see chapter 11.3.
506_acid density 1.28 kg/l
Nominal acid density of electrolyte, should be entered as defined
in the manufacturer’s instructions to accelerate its adaptive de-
termination by the Sunny Island.
507_SOC ini
0.0 %
Initial degree of battery charge, should be entered if known to
accelerate its adaptive determination by the Sunny Island.
If “0.0” is set, the Sunny Island estimates the degree of battery
charge based on the battery voltage.
402_Uconv nom
230.0 V
Setpoint value of AC voltage that the Sunny Island is to provide
as grid-forming element (RUN_U)
403_Fconv nom 50.00 Hz
(60.00 Hz)
Setpoint value of AC frequency that the Sunny Island is to pro-
vide as grid-forming element (RUN_U)
