C.1.3 The Battery charger
The built-in battery charger is capable of charging the batteries quickly and
completely. A microprocessor controlled, 3 to 4 Step charging process ensures
the optimum charging of the batteries. The desired charging current can be set.
The battery charger can be used for lead-acid or gel batteries. Thanks to the
floating charge ability of this unit,
the batteries can remain continuously connected.
C.1.4 The solar charge regulator (opetional)
With the built-in solar regulator, the unit is a complete solar-power-center. In a
solar installation this regulator ensures that the batteries are charged correctly.
With the unit, batteries can be charged with a generator and with the solar
modules at the same time. The charging of batteries with both energy sources is
carried out fully automatically.
C.1.5 Remote control
As an option, a remote control can be connected to this unit
. The
remote control is supplied with a 3m long cable. This cable ca n be up to 15m long.
(RS-485 interface) On the remote control output current and charging current are
also shown.
C.2 Battery connections
Lead-acid batteries are normally available in blocks of 2V, 6V or 12V. In most
cases, to generate the necessary operating voltage and the capacity of the
batteries for the unit many batteries have to be connected together in parallel
and or in series. Following three examples are shown:
