Steca PL 2085

Solar Charging Station

The PL 2085 is a solar charging station which charges up to 8 leadacid
batteries simultanously. The microprocessor controlled charging
station recognizes the connection sequence of the batteries. The
battery which is connected first is charged first and as soon as the
first battery is full, it switches over to the second battery etc.
Every battery terminal of maximum 5 Amps is a seperate DC / DC
converter with maximum power point tracking (MPP) of the solar
generator. Up to two battery terminals can be connected in parallel
on the same battery. These terminals are protected against wrong
polarity, short circuit, no load operation and overload. Batteries are
charged to predefined IU constant current charging procedures until
end of charge voltage is reached. Battery charging starts even
from run down batteries at voltages higher than 5V. At night the
charging station works in a energy saving mode and no battery data
is lost.
