If you do not have external module switches you have to connect the battery first and then the module
input to support the automatic voltage identification in 12/24V systems.
3 Application range
The system controller can be used in PV energy supplies with battery storage within the field of business
and commerce as well as in firms and telecommunication devices.
Although the case is IP65 waterproofed it should be protected against heavy rain or direct sun.
In order to keep the voltage drop between controller and battery to a minimum please use only short
battery cables.
To adapt the final charge voltage of the battery for optimal charging the attached temperature sensor
should be mounted next to the battery clamps.
The controller should only be used for regulating solar modules. It regulates the charging current from the
modules using the shunt (short circuit) principle. However, the battery can also be charged by multiple
PowerTaroms or other sources with appropriate battery charge functions.
3.1 Power range
The controller can be used in a wide range of performance and
temperature. It automatically registers the maximum permissible
temperature and disconnect the loads in the case it is exceeded.
Now the complete radiating surface of the heat sink could be
used for the power loss produced during charging.

Select dimensioning in a way that the ambient temperature line is
not exceeded in the case of maximal charge and discharge
currents. With an ambient temperature of 20 °C and correct
installation the controller can process both module and load
nominal currents (see labels). These nominal currents
correspond to 100 % in the diagram.
3.2 Options
The System-Manager can be operated with the following additional devices which you can purchase at
authorized dealers. The options of description and instructions are pointed out by following listed
possibilities and examples of use:
⇒
External current sensors can be installed in the power
wires of generators or loads that are not being controlled
by the System-Manager directly. This enables the
System-Manager to calculate the state of charge (SOC)
even when external sources like wind or diesel
generators charge the battery, or when bigger loads like
inverters are connected directly to the battery. The
shunts register the current and send the current readings
into the System-Manager digitally.

•
The pair-shunt solution enables separate measurement and indication of charging and
discharging currents. All load and charging currents have to be conducted across either the
charge or discharge current measuring shunt, except for those currents already flowing through the
System-Manager (the System-Manager already measures these currents internally automatically).
