For example, five solar modules each rated at 55 Wp can be connected in
parallel:
Per solar module e.g. U

The temperature correction of end-of-charge voltages is --20 mV per degree
of temperature increase (in relation to 25

C) or +20 mV per degree of tem-
perature reduction (voltage limits: U

14.9 V; the top voltage
limit at 14.9 V is in consideration of the maximum input voltage of the consu-
mers connected).
