4�2 Wiring Solar connections
This clause describes the connection between the solar panels and the PowerRouter.
Before connecting the PV string connectors to the PV terminals check this list:
•
Set DC switch on the PowerRouter to OFF
• Use copper wire (4 mm 2 ) for all PV wiring connections to the PowerRouter; apply only solid or stranded wire. Do not use fine stranded
wire
• Verify that the DC solar current and voltage of your installation does not exceed the maximum rates specified on the type rating label
• Check the polarity of the PV strings
• Use special tool for connecting MC4 connector on the PV wires; the PV MS tool is described in Appendix D
Connect 1 or 2 strings to the PV input terminals using mating MC4 connectors.
The 3kW unit only has 1 PV input.
Do not connect 1 PV-string to both PV-terminals simultaneously (parallel connection).
Do not connect 1 PV-string to both PV-terminals in serial.
4�3 Bypass switch (for the professional models)
This clause describes the usage of a bypass switch.
The PowerRouter professional models use the 'Local Out' to supply your loads. This unique feature enables it to supply backup power in the
event of a grid failure, as a PowerRouter with a 'Local Out' connection can switch to 'island mode' when the grid fails. After a short delay it
resumes operation, enabling its unique 'Local Out' connection to supply a stable 230Vac power signal to the connected loads.
Bypass switches are crucial components with which the PowerRouter supports critical load situations. (The PowerRouter acts as a UPS
system). The bypass switch allows you to switch off the PowerRouter for maintenance, without cutting power to the load. When the switch
is activated, the mains supply is directed away from the PowerRouter and is directly connected to the load. The PowerRouter can then be
serviced and any maintenance work carried out without disturbing the load. Once the PowerRouter is ready to be switched on, the bypass
switch is deactivated and the supply is redirected to the PowerRouter; the load receives the PowerRouter supply again.
The Bypass switch is an optional component and should be obtained and installed separately. (Bypass switch contacts ratings = 230V 40A).
The AC grid input and AC local output circuits are isolated from the enclosure and system grounding.
AC grounding: connect the PowerRouter to the AC ground from the utility via the ground terminal (PE).
PV Grounding: check local regulations. DC Grounding Electrode Conductor: a DC grounding electrode conductor may be required by the
local authorities. The AC local out connection of the PowerRouter is an optional connection, depending on how the PowerRouter will be
used.
4�4 Internet connection
This clause describes the connection of the PowerRouter to the internet.
When the PowerRouter is connected to the internet, the web portal myPowerRouter.com gives detailed system information (e.g.
performance, profit, solar yield) on each PowerRouter unit. The PowerRouter can even be remotely updated with new firmware containing
the latest features, so your system is always up to date.
Connecting the PowerRouter to the internet with standard UTP / RJ45 network cable to your internet router / gateway / switch.
More information about possible connections to the internet is available on www.PowerRouter.com.
The PowerRouter only uses Internet port 80, this is normally a standard setting of the network. It can be tested by connecting a PC to this
connection and trying to surf on the internet. In case of applying a proxy, contact your installer/dealer.
