3.3 3-phase sensor (accessory PRA3SENSE)
With the signal from the 3-phase sensor, the PowerRouter determines the energy export and consumption
with the public grid for a 3-phase system, and compensates on 1-phase if a compensating electric meter is
used. The 3-phase sensor is a measuring point for energy management and can be used for clipping the
grid.The 3-phase sensor can be ordered via your local Business Partner.
3.4 External relay (accessory PRA1RLY)
You can use the external relay to:
• Energy management (figure 10).
If the amount of solar energy fed to the public grid exceeds the programmed value, the PowerRouter
can switch on additional loads via the external relay. How long the load stays switched on can be
programmed in the PowerRouter, via advanced settings in the software installation tool.
• Isolate the PowerRouter from the public grid by a ripple control receiver (figure 13).
The ripple control receiver is not included. The disconnection is according to the German directive
EEG2012. Only the disconnect contacts of the relay are used.
The external relay can be ordered via your local Business Partner.
3.5 Wireless Energy Management Kit (accessory PRA1WEMK)
The Wireless Energy Management Kit can be used with PowerRouter products that support energy
management. If the amount of solar energy fed to the public grid exceeds the programmed value, the
PowerRouter can switch on additional loads via the Wireless Energy Management Kit. The Wireless
Energy Management Kit is available in several country dependend versions and can be ordered via your
local Business Partner. The Wireless Energy Management Kit contains a:
• Binary input module (Eaton CBEU-02/xx).
• Wireless plug-in actuator (Eaton CSAP-01/xx).
3.6 Batteries
The PowerRouter models function with any 24V lead-acid batteries. Proper settings can be made via
advanced settings in the software installation tool.
CAUTION
Never exchange 24V batteries with 48V batteries or vice versa.
i
Always check the specifications of the supplier, before making the settings.
3.7 Battery temperature sensor (standard)
The battery temperature sensor is installed on the 24V lead-acid batteries. The PowerRouter uses the
sensor input to optimise charging of the batteries. When the batteries overheat, the PowerRouter stops
charging the batteries. Proper settings can be made via advanced settings in the software installation tool.
