e Read all the instructions and cautions in the manual before beginning the
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.
EN 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
Ensure PV input voltage does not exceed 55V 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.
EN Battery Safety
Lead-acid and LiFePO4 batteries can be dangerous. Ensure no sparks or
flames are present when working near batteries. Refer to battery
manufacturer's specific charging rate setting. Do NOT charge improper
battery type.
Never attempt to charge a damaged battery, frozen battery, or
non-rechargeable battery.
Do NOT let the positive (+) and negative (-) terminals of the battery touch
each other.
Use only sealed lead-acid, flooded, gel or LiFePO4 batteries that 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.
If battery acid contacts skin or clothing, wash immediately with soap and
water. If acid enters eye, immediately flush eye running with cold water for
at least 10 minutes and get medical attention immediately.
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

Optional Component
The Voyager is shipped by itself with no additional components. Optional
components that require a separate purchase:
Voyager Temperature Sensor: Measures
the temperature at the battery and uses this data
for very accurate temperature compensation. The
sensor is supplied with a 9.8ft cable length that
connects to the charge controller. Simply connect
the cable and adhere the sensor on top or the side
of the battery to record ambient temperature
around the battery.
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 controller.
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.
The Voyager is designed for vertical mounting on a wall.
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 (Back)

The solar controller should be installed as near the battery as
possible to avoid efficiency loss.
When the connections are completed correctly, the solar
controller will turn on and begin working automatically.
After connecting the battery to the charge controller, the controller will turn on
automatically. Assuming normal operation, the charge controller will cycle
through different display. They are as follows:

Four Charging Stages
The Voyager 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.
PWM Technology
The Voyager 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.
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 minutes.
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. If 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.
E Lithum Battery Activation
The Voyager 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 Voyager 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.
When using the Voyager to charge a 24V lithium battery bank, set the system
voltage to 24V instead of auto recognition. Otherwise, the over-discharged 24V
lithium battery will not be activated.
Incorrect battery type setting may damage your battery.
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.
