THE SOLAR REGULATOR REMOTE MONITOR
The REDARC Solar Regulator Remote Monitor allows users to monitor how their solar panels are performing
and keep track of the charge state of the battery/s being used.
The unit is simple to setup and control and provides an easy to read graphical interface, which can be
modified to suit the users preferences.
WARNING & SAFETY INSTRUCTIONS
INST126-1
SAVE THESE INSTRUCTIONS — This manual
contains IMPORTANT SAFETY INSTRUCTIONS for
the REDARC Remote Monitor for REDARC Solar
Regulators.
DO NOT OPERATE THE SOLAR REGULATOR UNLESS
YOU HAVE READ AND UNDERSTOOD THIS MANUAL
AND THE SYSTEM IS SETUP AS PER THESE
INSTRUCTIONS. REDARC RECOMMENDS THAT
ANY REGULATOR/CHARGER BE INSTALLED BY A
SUITABLY QUALIFIED PERSON.
WARNING
RISK OF EXPLOSIVE GASES:
Working in the vicinity of a lead-acid battery is
dangerous. Batteries generate explosive gases
during normal operation. For this reason, it is of
utmost importance that you follow the instructions
each time you use the Regulator.
CAUTION
1. Solar Regulators should not be used by persons
(including children) with reduced physical,
sensory or mental capabilities, or lack of
experience and knowledge, unless they are
supervised or have been instructed on how to
use the appliance by a person responsible for
their safety. Children should be supervised
to ensure that they do not play with the Solar
Regulator.
2. Do NOT use the Solar Regulator to charge
non-rechargeable batteries. Doing so may
result in harm to the user and/or damage to the
regulator and/or solar blanket. Only use the
Solar Regulator for charging standard lead acid,
calcium content, Gel & AGM type 12V batteries.
3. Check the battery manufacturer’s data for your
battery and ensure that the voltage of the
charging profile you select does not exceed the
manufacturer’s recommended maximum
charging voltage. If the absorption and boost
voltage for your battery type is too high, please
select another charging profile. Do not change
the original settings without confirming the
battery manufacturer’s recommendations or
consulting the battery manufacturer.
4. The Solar Regulator is not intended to supply
power to a low voltage electrical system
other than to charge a battery.
5. NEVER smoke or allow a spark or flame in
vicinity of battery or engine. This may cause
the battery to explode.
6. The remote monitor is not waterproof or
designed for installation under bonnet or
outdoors. Ensure the monitor is installed in a
cool and dry environment.
7. PERSONAL SAFETY PRECAUTIONS
To assist with the safe operation and use of the Solar
Regulator:
a) Wear complete eye protection and clothing
protection. Avoid touching eyes while working
near a battery.
b) If Battery acid contacts your skin or clothing,
remove the affected clothing and wash the
affected area of your skin immediately with
soap and water. If battery acid enters your eye,
immediately flood the eye with running cold
water for at least 10 minutes and seek medical
assistance immediately.

WARNING & SAFETY INSTRUCTIONS
c) If Battery acid contacts your skin or clothing, remove the affected clothing and wash the affected area
of your skin immediately with soap and water. If battery acid enters your eye, immediately flood the eye
with running cold water for at least 10 minutes and seek medical assistance immediately.
1. Designed for use with the REDARC SRPA solar regulator only.
2. The screen backlight will increase the current draw. Timing and durations of the backlight can be
adjusted to suit individual needs.
3. The communication data cable is an 8-Pin RJ45 type Ethernet cable. If a cable of different
length is required. REDARC recommend buying a cable of the required length rather than
shortening the supplied cable.
4. Do not forget your password. The factory default password is ‘000000’.
5. This user manual is to be read in conjunction with the REDARC SRPA Solar Regulator user manual.

The Remote monitor cable is equipped with 2 different styles of plug (as shown above). In order to fit within
the remote monitor’s mounting bracket — Plug A should be connected to the remote monitor and Plug B to
the regulator.
The communication data cable is an 8-Pin RJ45 type Ethernet cable. If a cable of different length is required,
REDARC recommend buying a cable of the required length rather than shortening the supplied cable.
