This manual contains important safety, installation, and
operating instructions for the charge controller. The following
symbols are used throughout the manual:
Indicates a potentially dangerous condition. Use
extreme caution when performing this task.
Indicates a critical procedure for safe and proper
operation of the controller
Indicates a procedure or function that is important
to the safe and proper operation of the controller.
E General Safety Information
* Read all of the instructions and cautions in the manual before
beginning the installation.
* There are no serviceable parts for this controller. Do NOT
disassemble or attempt to repair the controller.
* Make sure all connections going into and from the controller
are tight. There may be sparks when making connections,
therefore, make sure there are not flammable materials or
gases near installation.
E Charge Controller Safety
NEVER connect the solar panel array to the controller
without a battery. Battery must be connected first. This may
cause a dangerous occurrence where the controller would
experience a high open circuit voltage at the terminals.
Ensure input voltage does not exceed 50 VDC to prevent
permanent damage. Use the Open Circuit (Voc) to make
sure the voltage does not exceed this value when connecting
panels together in series.
The charge controller should be installed indoors in a
well-ventilated, cool, and dry environment.
Do NOT allow water to enter the controller.
H Battery Safety
Do NOT let the positive (+) and negative (-) terminals of the
battery touch each other.
Use only sealed lead-acid, flooded, gel or lithium batteries which
must be deep cycle.
Explosive battery gases may be present while charging. Be
certain there is enough ventilation to release the gases.
Be careful when working with large lead acid batteries.
Wear eye protection and have fresh water available in case
there is contact with the battery acid.
Over-charging and excessive gas precipitation may
damage the battery plates and activate material shedding
on them. Too high of an equalizing charge or too long of
one may cause damage. Please carefully review the
specific requirements of the battery used in the system.
Equalization is carried out only for non-sealed / vented / flooded
/ wet cell lead acid batteries.
Do NOT equalize VRLA type AGM / GEL / LITHIUM batteries
UNLESS permitted by battery manufacturer.
Connect battery terminals to the charge
controller BEFORE connecting the solar panel
(s) to the charge controller. NEVER connect
solar panels to charge controller until the battery
is connected.

Battery Charging Parameters
General Information
The Wanderer is an advanced charge controller for off-grid solar
applications. Integrating highly efficient PWM charging, this
controller increases battery life and improves system
performance. It can be used for 12V/24V battery banks. The
controller is embedded with self-diagnostics and electronic
protection functions that prevent damages from installation
mistakes or system faults.

PWM Technology
The Wanderer utilizes Pulse Width Modulation (PWM)
technology for battery charging. Battery charging is a current
based process so controlling the current will control the battery
voltage. For the most accurate return of capacity, and for the
prevention of excessive gassing pressure, the battery is
required to be controlled by specified voltage regulation set
points for Absorption, Float, and Equalization charging stages.
The charge controller uses automatic duty cycle conversion,
creating pulses of current to charge the battery.
The duty cycle is proportional to the difference between the
sensed battery voltage and the specified voltage regulation set
point. Once the battery reached the specified voltage range,
pulse current charging mode allows the battery to react and
allows for an acceptable rate of charge for the battery level.
Four Charging Stages
The Wanderer has a 4-stage battery charging algorithm for a
rapid, efficient, and safe battery charging. They include: Bulk
Charge, Boost Charge, Float Charge, and Equalization.
Bulk Charge: This algorithm is used for day to day charging.
It uses 100% of available solar power to recharge the battery
and is equivalent to constant current.
Boost Charge: When the battery has charged to the Boost
voltage set-point, it undergoes an absorption stage which is
equivalent to constant voltage regulation to prevent heating and
excessive gassing in the battery. The Boost time is 120
Float Charge: After Boost Charge, the controller will reduce
the battery voltage to a float voltage set point. Once the battery
is fully charged, there will be no more chemical reactions and all
the charge current would turn into heat or gas.Because of this,
the charge controller will reduce the voltage charge to smaller
quantity, while lightly charging the battery. The purpose for this
is to offset the power consumption while maintaining a full
battery storage capacity.
In the event that a load drawn from the battery exceeds the
charge current, the controller will no longer be able to maintain
the battery to a Float set point and the controller will end the
float charge stage and refer back to bulk charging.
Equalization: Is carried out every 28 days of the month. It is
intentional overcharging of the battery for a controlled period.
Certain types of batteries benefit from periodic equalizing
charge, which can stir the electrolyte, balance battery voltage
and complete chemical reaction. Equalizing charge increases
the battery voltage, higher than the standard complement
voltage, which gasifies the battery electrolyte.
Once equalization is active in the battery charging, it will
not exit this stage unless there is adequate charging
current from the solar panel. There should be NO load on
the batteries when in equalization charging stage.
Over-charging and excessive gas precipitation may
damage the battery plates and activate material
shedding on them. Too high of equalizing charge or for
too long may cause damage. Please carefully review the
specific requirements of the battery used in the system.
Lithium Battery Activation
The Wanderer PWM charge controller has a reactivation
feature to awaken a sleeping lithium battery. The protection
circuit of Li-ion battery will typically turn the battery off and
make it unusable if over-discharged. This can happen when
storing a Li-ion pack in a discharged state for any length of time
as self-discharge would gradually deplete the remaining
charge. Without the wake-up feature to activate and charge
batteries, these batteries would become unserviceable and the
packs would be discarded. The Wanderer will apply a small
charge current to activate the protection circuit and if a correct
cell voltage can be reached, it starts a normal charge.

Connect battery terminal wires to the charge controller FIRST, then
connect the solar panel(s) to the charge controller. NEVER connect
solar panel to charge controller before the battery.
Do not over-torque or over tighten the screw terminals. This could
potentially break the piece that holds the wire to the charge
Refer to the technical specifications for max wire sizes on the
controller and for the maximum amperage going through wires.

Mounting Recommendations
Never install the controller in a sealed enclosure with flooded
batteries. Gas can accumulate and there is a risk of explosion.
1. Choose Mounting Location—place the controller on a
vertical surface protected from direct sunlight, high temperatures,
and water. Make sure there is good ventilation.
2. Check for Clearance—verify that there is sufficient room to
run wires, as well as clearance above and below the controller for
ventilation. The clearance should be at least 6 inches (150mm).
3. Mark Holes
4. Drill Holes
5. Secure the charge controller.

Risk of Electric Shock! Make sure that all power is turned off
before touching the terminals on the charge controller.
For best controller performance, it is recommended that these
tasks be performed from time to time.
* Check that controller is mounted in a clean, dry, and
ventilated area.
* Check wiring going into the charge controller and make sure
there is no wire damage or wear.
* Tighten all terminals and inspect any loose, broken, or burnt
up connections.
* Check to make sure none of the terminals have any
corrosion, insulation damage, high temperature, or any
burnt/discoloration marks.
Fusing is a recommendation in PV systems to provide a safety
measure for connections going from panel to controller and
controller to battery. Remember to always use the recommended
wire gauge size based on the PV system and the controller.
