General Safety Information

Charge Controller Safety

This manual contains important safety, installation, and

operating instructions for the charge controller. The following

symbols are used throughout the manual:

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.

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.

Read all of the instructions and cautions in the manual before

beginning the installation.

Important Safety Instructions

Please save these instructions.

extreme caution when performing this task.

operation of the controller

Indicates a procedure or function that is important

to the safe and proper operation of the controller.

NOTE

CAUTION

WARNING

Battery Safety

The charge controller should be installed indoors in a

well-ventilated, cool, and dry environment.

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.

Do NOT allow water to enter the controller.

General Information

4-Stage PWM Charging: Bulk, Boost, Float, and Equalization

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.

Automatic Voltage Detection for 12V/24V Non-Lithium

Systems and Lithium Battery Activation

Back-lit LCD for displaying system operation, diverse load

control, and error codes if any

Preset for Deep Cycle Sealed, Gel, Flooded Batteries and

Lithium-iron Phosphate Batteries

Integrated 5V, up to 2.1Amp USB for mobile or portable

device charging

Protection Against: overcharging, over-current, short circuit,

reverse polarity

Bluetooth Monitoring Ready port with addition of BT-1

Module and Renogy DC Home App

Renogy BT-1 Bluetooth Module (Model: RCM-BT1)

The RCM-BT1 is a great addition to Renogy

charge controllers with an RS232 port. Pair the

controller using the BT-1 Module and the

Renogy DC Home App to monitor your system

using a smart phone or tablet. Read or set

parameters to monitor your system in real time!

Refer to the technical specifications for max wire sizes on the

controller and for the maximum amperage going through wires.

Do not over-torque or over tighten the screw terminals. This

could potentially break the piece that holds the wire to the

charge controller.

CAUTION

Installation

Connect the battery to the charge controller BEFORE

connecting the solar panel(s) unless you have the solar

suitcase with controller exception. The controller needs a stable

power source to operate.

WARNING

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 tempera-

tures, 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).

WARNING

3. Mark Holes

4. Drill Holes

5. Secure the charge controller.

Mounting Recommendations

Use bare wiring when connecting to the Wanderer’s terminal

blocks. Due to default positioning, you must ensure that the

terminal hatch is completely open before the first-time use.

1.Make sure to rotate the hatch counterclockwise (CCW) into

the open position to expose the wire hatch

3.Rotate clockwise (CW) to until the hatch has closed and

clamped onto the wire

2.Insert bare wire into the terminal for the respective connection

Wiring and Fusing

NOTE The wire terminals are closed by default.

Depending on the PV Array wiring and battery size, the

recommended fuse and cable gauge will depend on the actual

amps flowing through the cable. The following chart accounts for

less than 3% voltage drop and may not account for all configura-

tions.

*Panel connection assumes series to meet 24V system

minimum setup.

Larger wire sizes generally improve performance, whereas

smaller wire sizes may reduce performance, especially if

undersized. When considering wiring, fusing, and connection

options, think big and short as possible as heavier components

and shorter wire length offer less resistance and voltage drop.

Terminal Size Limitations may apply.
