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 terminals. 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 connected. 03 Table of Contents General Information Dimensions Optional Component Installation Mounting Recommendations Wiring Wire AWG Operation Change the Parameters 1.

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. Installation 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.

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.
