Installation & Operating Instructions
Description
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.
Lead-acid battery with...
Lead acid:
... liquid electrolyte
Fleece:
... electrolyte bound in fleece
Gel:
... electrolyte bound in gel
Nominal battery voltage. Normally 60 V have to be set. For ex-
ceptions see chapter 11.3.
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.
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.
Setpoint value of AC voltage that the Sunny Island is to provide
as grid-forming element (RUN_U)
Setpoint value of AC frequency that the Sunny Island is to pro-
vide as grid-forming element (RUN_U)
