THE SOLAR REGULATOR REMOTE MONITOR
The REDARC Solar Regulator Remote Monitor allows you to monitor how your solar panels are performing and
keep track of the charge state of your battery/s.
The unit is simple to setup and control and provides an easy to read graphical interface, which can be
modified to suit your preferences.
WARNING & SAFETY INSTRUCTIONS
INST127-2
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 and 24V
batteries.
3. Over Charging Hazard. Failure to connect solar
panel’s negative wire directly to the
regulator may result in overcharging the battery.
The solar panel’s negative wire must
be connected directly to the regulator only.
4. 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. The Solar
Regulator is not intended to supply power to
a low voltage electrical system other than to
charge a battery.
5. Electrical Hazard. Incorrect connection of
batteries and solar panels in Parallel or Series
can subject the regulator to high voltages that
will damage the regulator. Ensure the
recommended connections and sequences are
followed and that the rated current, wattage or
voltage of the regulator is not exceeded.
6. NEVER smoke or allow a spark or flame in
vicinity of battery or engine.
This may cause the battery to explode.
PERSONAL SAFETY PRECAUTIONS
7. 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
1. Designed for use with the REDARC SRP 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 SRP Solar Regulator user manual.

System Checking
At any time pressing and will trigger a system check. The system check will advise of the status
of the battery 1, battery 2, solar and temperature conditions as well as performing a check of the LCD icons.
The monitor will show ‘open’ for a currently open connection due to over-voltage of charge priority, and will
show ‘no’ if a battery or temperature sensor is not connected.
Fault Indicator
The symbol indicates that a fault has occurred. This symbol will advise of over-voltage, open-circuit,
no temperature sensor, battery disconnect, over current and panel short-circuit conditions. The symbol will
disappear when the fault is removed and the monitor and regulator restart.
Data Repeat Option
The data repeat option can be set to cycle through panel, battery or temperature data. When the data repeat
option is set to ‘auto’ the monitor will cycle through the available data for the selected group. Pressing the
button will cycle between solar, battery 1, battery 2 and temperature groups, pressing or will
cycle back or forward through the data for that group.
