Solar Charge Controller Solara SR135TL
User Manual English, Page 1
Dear Client,
Thank you very much for buying a Solara product. With your new Solara SR135TL
controller you own a state-of-the art device which was developed according to the
latest available technical standards. It comes with a number of outstanding features,
like:
§ Clear, readable display of the state of charge
§ Acoustic signal when the state of charge changes
§ Low voltage disconnect regulated by state of charge or voltage
§ 16 mm² connector clamps
§ Complete electronic protection
This manual gives important recommendations for installing, using and
programming as well as remedies in case of problems with the controller. Read it
carefully in your own interest and mind the safety and usage recommendations at
the end of this manual.

Description of Functions

§ The charge controller protects the battery from being overcharged by the solar
array and from being deep discharged by the loads. The charging characteristics
include several stages which include automatic adaptation to the ambient
temperature.
§ The charge controller adjusts itself automatically to 12V or 24V system voltage.
§ The charge controller has a number of safety and display functions.

Mounting and Connecting

The controller is intended for indoor use only. Protect it from direct sunlight and
place it in a dry environment. Never install it in humid rooms (like bathrooms).
The controller measures the ambient temperature to determine the charging
voltage. Controller and battery must be installed in the same room.
The controller warms up during operation, and should therefore be installed on a
non flammable surface only.
REMARK: Connect the controller by following the steps described below to avoid
installation faults.
Mount the controller to the wall with screws that fit to the
wall material. Use screws with 4 mm shaft and max. 8 mm
head diameter, no counter sunk. Mind that the screws have
to carry also the force applied by the wiring.
Make sure that the ventilator slits on the sides are
unobstructed.
A DIN Rail mounting plate is available for mounting standard 35mm DIN Rail.
Connect the wires leading to the battery with correct
polarity. To avoid any voltage on the wires, first connect the
controller, then the battery. Mind the recommended wire
length (min 30 cm to max approx. 100 cm) and the wire size:
min 4 mm².
Wrong polarity will cause a permanent warning sound.
WARNING: If the battery is connected with reverse polarity, the load terminals
will also have the wrong polarity. Never connect loads during this condition!
REMARK: Mind the recommendations of your battery manufacturer. We strongly
recommend connecting a fuse directly to the battery to protect any short circuit at
the battery wiring. The fuse must take the charge controller nominal current:20A.
Connect the wires leading to the solar array with correct
polarity. To avoid any voltage on the wires, first connect the
controller, then the solar array. Mind the recommended wire
size: min 4 mm²
REMARK: Place positive and negative wire close to each other to minimize
electromagnetic effects.
REMARK: Solar panels provide voltage as soon as exposed to sun light. Mind the
solar panel manufacturer's recommendations in any case.
Connect the wires leading to the loads with correct polarity.
To avoid any voltage on the wires, first connect the wire to
the load, then to the controller. Mind the recommended
wire size:min 4 mm².
Grounding the Solar System
REMARK: If the device is used in a vehicle which has the battery negative on the
chassis, loads connected to the controller must not have an electric connection to
the car body, otherwise the Low Voltage Disconnect and electronic fuse functions
of the controller are short circuited.
Starting up the Controller
Self Test
As soon as the controller is supplied with power either from the battery or the
solar array, it starts a self test routine. Then the display changes to normal opera-
tion.
System Voltage
The controller adjusts itself automatically to 12 V or 24 V system voltage.
As soon as the voltage at the time of start-up exceeds 20.0 V, the controller
implies a 24 V system.
If the battery voltage is not within the normal operation range (ca. 12 to 15.5 V or
ca. 24 to 31 V) at start-up, a status display according to the section ERROR DE-
SCRIPTION occurs.
Battery Type
The controller is preset to operate with lead acid batteries with liquid electrolyte.
If you intend to use a lead-acid battery with solid electrolyte ('gel' type or 'fleece'
type) you can adjust the charging characteristics (see "Settings"). The equalization
charge is deactivated then.
In case of any doubts consult your dealer.
Recommendations for Use
The controller warms up during normal operation.
The controller does not need any maintenance or service. Remove dust with a dry
tissue.
It is important that the battery gets fully charged frequently (at least monthly).
Otherwise the battery will be permanently damaged.
A battery can only be fully charged if not too much energy is drawn during charging.
Keep that in mind, especially if you install additional loads.
Display Functions
The controller is equipped with 5 LEDs and an acoustic warning signal.
Load status display
State of charge display
Load status display
In normal operation, the controller shows the state of charge of the battery and
the charge from the solar panels. Any change of the state of charge (SOC) to a
lower status is additionally signaled acoustically.
Charge display
Solar array supplies electricity Solar array does not supply electricity
State of charge display
>75% 25-75%
The percentage corresponds to the available energy until Low Voltage Disconnect
in relation to a fully charged battery.
Acoustic signals
A change in the state of charge (SOC) to a lower status is indicated by an acoustic
signal.

3x
The loads are disconnected approx. 1 minute after a series of 25 signals.
Load status display
In case of deep discharge or overload/short-circuit of load, the load output is
switched off. This is indicated by:
Normal operation Low voltage disconnect
Be aware that the positive terminals of the
Solara SR135TL controller are connected
internally and therefore have the same
electrical potential. If any grounding is
required, always do this on the positive
wires.
