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 no flammable materials or gases near the installation.

Charge Controller Safety

• NEVER connect the solar panel array to the controller without a battery. The 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.

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 the charge controller until the battery is connected.

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.

Key Features

• Automatically detects 12V or 24V DC system voltages, 10A Charging Capacity
• Deep Cycle Sealed, Gel and Flooded battery options
• 4 Stage PWM charging: Bulk, Boost. Float, and Equalization
• Temperature compensation and correcting the charging and discharging parameters automatically, improving battery lifetime
• Protection against: overcharging, over current, short-circuit,reverse current and reverse polarity
• Backlit LCD screen for displaying system operation, diverse load control and error codes
• Integrated 5V 2A USB ports for extra charging
• Integrated communication port for remote monitoring
• Charges over-discharged lithium-ion batteries
• Negative ground charge controller

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 retum 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 currant 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 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 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.

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 reactions. 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 the 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 tum 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

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.

Fuse from Controller to Battery
Controller to Battery Fuse = Current Rating of Charge Controller Ex. Wanderer 10 = 10A fuse from Controller to Battery

Fuse from Solar Panel(s) to Controller
Ex. 200W; 2 X 100 W panels

Parallel
Total Amperage = Isc1 + Isc2 = (5.75A + 5.75A) * 1.56
Fuse = minimum of 11.5 * 1.56 = 17.94= 18A fuse

Operation

Interface description

Use steps

1. Connect and check the current: Power on after completing the connection as shown, the screen should display capacity percentage. If the screen has no response, please check the connection. Then charge or discharge the battery and check whether the display current is equal to the actual current. If the deviation is large, please check the connection.
2. Capacity calibration: On first use, the percentage and capacity are not the actual value, you need to calibrate the capacity to either 100% or 0%.
   First set the usable AH capacity of the battery as the preset AH capacity.
   For Lithium and Sealed Lead Acid batteries to calibrate to 100% charge the battery fully and hold the “up” key for 3s to set the capacity to 100%
   For Lithium batteries to calibrate to 0% discharge the battery completely and hold the “down” button key for 3s to set the capacity to zero.
   This will only have to be done on initial installation of the Renogy Battery Monitor or if the Battery Bank is replaced.
3. Check and reset the actual capacity: If you find the displayed capacity doesn’t match the actual capacity during use, please check and reset the actual capacity.
   For Lithium batteries discharge the battery to 0% and hold the “down” key for 3s to set the capacity to 0, then set the preset capacity as large as possible.
   Now charge the battery fully and the displayed AH capacity should be the actual usable capacity. Then set the displayed AH capacity as the preset AH capacity.
   For Sealed Lead Acid batteries it is recommended to set the AH lower than the usable rating after conducting a capacity test or consulting the battery manufacturer.

User settings

Preset capacity and voltage setting:

1. Press the key for 3s to enter setting menu;
2. Click or key to select the setting items:
   • CAP—Preset capacity: An initial capacity has been set at the factory, please set it according to the real capacity of your battery.
   • HIGH V-Full capacity voltage: When the voltage is higher than the set value, the capacity will be automatically set to 100%.
   • LOW V-Zero capacity voltage: When the voltage is lower than the set value, the capacity will be automatically set to 0%. If the discharge continues, the voltage value will flash, and the alarm will beep once every 10s.
   • ALARM-Alarm setting: When the battery capacity is below the set capacity, the percentage and battery symbol will flash and the alarm will beep once every 10s.
   • Attention: If you need to set the HIGH V and LOW V values, please confirm the full charge voltage and all discharge voltage specifications of your battery.
3. Select CAP and click the key to enter the preset capacity setting; The set value will flicker, click the key can select other values, click the  or key to select the correct values after this click the key to quit preset capacity setting.
4. We can set other items with the same method as preset capacity. When all the items are set and all the values are correct, click the key to save the set and quit the setting menu.

Set capacity to zero or full:

On first use or change of the battery bank, the memory capacity should be set zero or full: In the main interface, hold the key for 3s to set the capacity zero, the percentage will be 0%; hold the key for 3s to set the capacity full, the percentage will be 100%.

Sleep mode wake up operation

1. When the battery current is low, the Renogy Battery Monitor will go into a low power sleep mode, press any key to see the display if needed. When the battery current rises over normal value or the battery starts charging or discharging the Renogy Battery Monitor will wake up.
2. The Renogy Battery Monitor can stay connected to the battery bank since it has a very low self-consumption.

Manual turn off backlight function

While charging the battery, the LCD screen’s backlight will also be slowly flashing. In order to turn off the backlight function, Long press front Keyboard can turn off the backlight, Long press again Keyboard can Wake up the backlight.

Troubleshooting

• When connecting the load, if the backlight is blinking, the B- and P- of the shunt are wired inversely.
• When the battery current is low the Renogy Battery Monitor will enter a low power (sleep mode) and the backlight will turn off, press any button and the backlight will turn on for 10s.
• When the current changes frequently the data acquisition may produce an error, and it may affect the accuracy.
• When charging or discharging. The Renogy Battery Monitor will be working and the capacity displayed will be real-time numbers.
