1 Introduction

This manual describes the wiring of the PowerRouter for Self-use. This manual should be used in combination with the PowerRouter Installation
Manual for proper installation. With the PowerRouter for Self-use, you can use as much of your own generated energy as possible and be
independent of the grid.

2 Safety

!
Before installing or using the PowerRouter, read all of the instructions, cautions and warnings concerning the PowerRouter, solar panel and
battery bank as well as those in this installation manual. Contact the local utility company before connecting the PowerRouter to the electric
grid.
WARNING
Solar panels produce electrical energy (600V, 15A) when exposed to light and can thus create an electric shock hazard. Wiring of the solar
panels should only be performed by qualified personnel. To prevent short circuiting of the battery, an insulated box wrench should be used.
The PowerRouter contains no user-serviceable parts. Contact your installer/dealer for all repairs and maintenance.

3 Configurations

Your PowerRouter can be configured in two different ways:
1. Self-use without emergency backup
1
2. Self-use with emergency backup
2
Self-use without emergency backup only makes use of the AC GRID connection. Self-use with emergency backup makes use of both the AC
GRID and AC LOCAL OUT connections on the PowerRouter. The advantage of the Self-use with emergency backup function is that when
there is a power outage of the grid, your load will be supplied with your own generated and/or stored energy.
9
with emergency backup configuration, you have to install an external relay between AC GRID and AC LOCAL OUT. The relay coil is energized
by the AC GRID supply.
If there is no sunlight during the power outage, the only power available for consumers is that from the battery. If the battery is discharged, the system
1
will no longer be able to provide power.
In general, power consumption is higher during the winter due to the additional consumers that are in use. Combined with the lower yield from the solar
2
panel (fewer hours of sunlight per day), this can cause the battery to become discharged.
To prevent this situation the PowerRouter has a winter mode. When the winter mode becomes active, the battery is fully charged and then disconnected
from the system. The consequences are that:
• The battery is fully charged when winter begins. This is beneficial to the battery's service life.
• Because the battery cannot be used during the (configurable) winter period, there is no emergency backup available from the battery, even if the
power fails.
By default, winter mode is set for the period from 1 December to 1 February. These settings can be changed via the installation tool.
For all configurations it is recommended that the PowerRouter be installed as close to the meter cupboard as possible.
3�1 Energy meters
You need a minimum of two energy meters (9e) to determine the generated, purchased and exported energy. Depending on the meter type,
3
you can use either 1 energy meter with 1 counter and 1 energy meter with 2 counters, or 3 energy meters with 1 counter each.
3�2 Current sensor
The current sensor (8a) measures the current on the phase wire that runs between the PowerRouter and the grid. This enables the
4
PowerRouter to determine the power requirements of the connected consumer. The current sensor is connected on the CAN-bus on the
PowerRouter. Remove the protective cap from the PowerRouter's CAN connector before making the connection.

6
• Place the current sensor (8a) around the phase wire (L) to which the PowerRouter is connected
• Place the current sensor (8a) around the phase wire (L) to measure the current going to and coming from the grid
7
• Make sure the current sensor (6) is installed in the right direction: the arrow on the sensor must point toward the public grid.
Don'ts
• Do not place the current sensor (8a) on the N-wire (neutral) or the earth wire
• Do not place the current sensor (8a) on the N-wire and L-wire simultaneously
• Do not place the current sensor (8a) on the L-wire going to the consumer
• Do not place the current sensor (8a) with the arrow pointing toward the energy meter
• Do not place the current sensor (8a) over non-insulated wires
• Do not place the current sensor (8a) on a phase other than the one connected to the PowerRouter.
Use a CAT5 UTP cable (8c) with a maximum of length of 10 metres and connect this cable between the PowerRouter CAN port and UTP
8
coupler to which the current sensor (8a) is also connected.
