SYSTEM INSTALLATION
ANGLE TO THE SUN
REDARC solar panels will perform at their peak with the panel face angled directly towards the sun.
In practice this is not always achievable, so REDARC recommend having your panels face NORTH at
an angle of between 20° and 40° from the ground. This will ensure the best total output from your
panel across the course of the day, no matter what season.
In the southern hemisphere, the sun is always in the NORTH half of our sky. As such facing your
panel NORTH ensures the best angle to the sun for a fixed panel across the course of the day.
The optimal angle from ground of the panel is around 30°. Anywhere between 10° and 40° ensures
good power generation across the course of the day.
SYSTEM WIRING
INSTALLATION NOTES
• Before connecting your solar panel confirm the battery is properly connected.
• Always ensure the connection at Anderson plug is clean, sound and is wired with the correct polarity.
• Redarc recommend the regulator be installed as close as possible to the battery/s. If you need to
use different cables ensure their length does not exceed 10m from the panel to the regulator.
• The supplied MC4 connectors are suitably rated for up to 30A, if multiple panels are used to the point
of exceeding this rating, alternative connectors should be sourced.
• When connecting panels from an existing setup, or non-Redarc brand panels, please ensure that the
panels are diode protected, as they may be damaged if they are not.
• Please refer to Solar Regulator manual and Battery Manufacturer’s specifications for specific
installation instructions.
