Installation Planning
Planning Preparations
This section provides information to help plan for a basic installation of the
Conext SW. There are two key factors that will have a major impact on system
performance.
1. Size and Length of DC Cables
To select the appropriate size and length of DC cables, see “DC Cabling” on
page 1–14.
The DC cables should be as short as possible and large enough to handle the
required current, in accordance with the electrical codes or regulations
applicable to your installation. If there are long battery cables which are in
excess of 3 meters each and not of sufficient size, the voltage drop across the
cables will have a negative impact on overall system performance.
2. Mounting Location of the Conext SW
See “Step 1: Choosing a Location for the Inverter/Charger” on page 1–19.
Components of the Inverter Power System
Inverter power systems vary depending on the power requirements of the user
and where the user is located. Inverter power systems typically involve one AC
source, one DC source, one inverter/charger, and a control and monitoring
device.
One example is an off the grid house with an AC generator, a battery, and a
Conext SW inverter/charger with a System Control Panel (SCP). Another example
is a house in the city, that is connected to the power grid but needs a power
backup solution to cope with rolling blackouts during summer. Some power
systems involve harvesting renewable energy such as solar energy in
conjunction with off-grid or power backup solutions.
Before installing a Conext SW inverter/charger, know your power requirements
then divide the components of the power system into AC, DC, and Xanbus
network devices. Xanbus network devices control and monitor the Conext SW
inverter/charger as well as AC generators and solar panels.
