2: Lead-Acid
liquid electrolyte
503_Ubat nom
54 ... 60 V:
Nominal battery voltage. Normally set to 60 V. For excep-
tions see chapter 11.3.
504_Ubat min
51 ... 84 V:
Min. permissible battery voltage
505_Ubat max
51 ... 84 V:
Max. permissible battery voltage
506_acid density
1.1 ... 1.35 kg/l:
Nominal acid density as stated by manufacturer (only taken
into account if inverter is started via “New System“ or “New
Battery“ (see chapter 6))
507_SOC ini
0 ... 100 %:
Initial battery state of charge (only taken into account if in-
verter is started via “New System“ or “New Battery“ (see
chapter 6))
If set to “0“ the Sunny Island estimates the battery state of charge based on the
battery voltage.
508_Tbat Sense
0: Not Installed
Battery temperature sensor is not installed
1: Installed
Battery temperature sensor is installed
Automatically set to 1 in case of single-phase systems or masters in three-
phase systems. In all other cases set to 0.
Can be set to 1 for slaves with additional temperature sensors installed.
509_Tbat max
30 … 55 °C:
Max. battery temperature permissible
511_Bat Fan
Battery room fan installed:
0: Not Installed
Battery room fan not installed
1: Installed
Battery room fan is installed
512_Acid Pump
Only for lead-acid battery with liquid electrolyte:
0: Not Installed:
Electrolyte circulation pump is not installed
1: Installed:
Electrolyte circulation pump is installed.
By selecting “Installed“ the electrolyte circulation pump is switched on depend-
ing on the settings of parameters 513 to 516. Irrespective of the battery values,
however, there is at least one and maximum 9 circulations a day.
513_Circ time
1 ... 3600 s:
Run time of electrolyte circulation
516_Circ Qd
0.1 ... 50.0 %:
Electrolyte circulation is triggered as soon as the battery has
been charged with the corresponding ampere hours related
to its capacity (cumulative).
518_tset full
1 ... 180 d:
Time period after which full charge is to be made.
519_tset equal
7 ... 365 d:
Time period after which equalizing charge is to be made.
520_U float
2.2 ... 2.4 V:
Float charge voltage per cell
521_tVR charge
1 ... 600 min:
Charging time for normal charge (with gel or fleece batteries,
see “502_Bat Type”).
