• Select the appropriate operating mode according to local legislation and sunshine conditions.
• Keep the fixture away from shadows.
• Self-cleaning is available when the light fixture has a minimum tilt angle of 15 degrees.

Please save these instructions. Read all instructions carefully before installation or wiring. Do not open or attempt to repair the product yourself, as this may cause serious damage and void the warranty. Contact your local distributor for any installation questions.

The light module's range is 20-26 feet (6-8 meters). The ideal installation spacing is greater than 16 feet (5 meters). When installing multiple fixtures on one pole, select the desired operating mode before installation. Interference can cause delay or malfunction when using the remote control to change modes after installation.

Precautions when working with solar panels

When the solar panel is exposed to sunlight, a voltage appears at its output terminals, making it a source of electricity. To avoid shock hazard, cover the solar panel with an opaque (dark) layer such as paper or cloth during installation. Do not touch the terminals when the panel is exposed to sunlight or any other light source.

Diagram Description: The fixture dimensions are shown: 39.3 inches in length, 26.3 inches in height, and 5.6 inches in depth. Additional dimensions indicated are 7.8 inches, 8.7 inches, and 3.4 inches.

Specification

* The temperature can impact the battery's charging and normal operation. If your place's temperature is under 32°F, it is advised to use the Sunlike 50W Pro version.

* The solar charge time data is based on 77°F ambient temperature with the panel pointed directly at the solar radiation (1000W/m²).

Battery Notes

1. The LiFePO4-battery-powered SUNLIKE lights offer superior brightness and reliability compared to other outdoor solar lights.
2. Full battery charging may take 6 to 12 hours.
3. Output is reduced to 40% when the battery capacity is below 40%.
4. Battery charging stops when the ambient temperature is below 32°F or above 149°F.

Battery Status Indicator

The battery status is indicated by a red/green indicator on the lighting fixture:

• Red Indicator (Charging): Slow red light flashing indicates charging; solid red light indicates fully charged; quick red flashing indicates a charge fault.
• Green Indicator (Discharging): Solid green light indicates more than 40% battery capacity remaining; slow green light flashing indicates below 10% capacity; quick green light flashing indicates below 0% capacity (battery protection mode).

Storage

To avoid over-discharge during storage, recharge the lighting fixture every 3 months using the dedicated charger. Reset the switch when done.

ATTENTION

It is NOT recommended to replace the battery pack yourself. Please contact SOLTECH for any battery-related questions.

(IAP) Intelligent Adaptive Program Battery Control Technology

To extend off-grid autonomy under challenging conditions (shady trees, heavy rain, thick clouds), our controllers feature an adaptive smart control that tracks battery capacity and adjusts light output accordingly. Previously, selecting a percentage on the remote determined the constant percentage of max LED brightness. With (IAP), the controller monitors the battery and regulates electrical current to the LEDs, applying the selected percentage relative to battery capacity rather than max LED output. This feature can increase off-grid performance by up to 40%.

Installation and Wiring Compliance

1. Installation and wiring must comply with State and National Electrical Codes.
2. The SUNLIKE 50W models are intended for outdoor use only. Avoid installation in unventilated areas and ensure the environment is within the product's operational temperatures.
3. The installation area should receive an average of 3.5 hours/day of sunshine to ensure full lighting fixture function. Avoid shaded areas.
4. Before installation, ensure the light pole and its foundation are solid enough to withstand the fixture(s).
5. Ensure the battery is fully charged before installation. Install during sunny days if possible.
6. Before installation, press the ON/OFF key on the remote control and check for a red light on the indicator. Cover the panel and verify the light module turns on normally within 1 minute.

After Installation

The lighting fixture will automatically turn on at night and turn off during daylight.

Important

• Always orient the solar panel facing the equator (e.g., facing south in the northern hemisphere).
• Always maintain a tilt angle of at least 15° to avoid dust accumulation (0° is a horizontal plane).

ATTENTION: Be careful with the solar board when you put SUNLIKE 50W on the pole.

Please loosen the screws to adjust the angle of the light.

Panel Angle

The solar charge in a battery pack won't last forever. The off-grid system relies on stored solar energy for autonomy. Angling your solar panels properly can boost the power intake of your solar lighting system. You want to angle your solar panels at a tilt based on the area's latitude.

Tip

You can increase the tilt by 15° in the winter or decrease it by 15° in the summer to get the maximum sunlight to recharge the battery bank.

Key

Sunlight Intensity: Strong sunlight, Normal sunlight, Less sunlight.

Best Facing Direction For The Solar Panel

Diagram Description: A diagram showing four directional views (N, S, E, W) with colored segments indicating optimal solar panel facing directions. 'Best' is shown towards South, 'OK' towards East and West, and 'Worst' towards North, with corresponding diagrams of panel orientation.

The area will dictate the installation of the fixtures and may sometimes prevent the lights from facing south. Panels facing West & East won't get as much light as Southern facing panels, but will still collect a good amount of sunlight. A North facing panel also works but will take longer to charge, meaning less optimal solar charge if installations face North.

World Wide Panel Angles

Diagram Description: A chart showing various latitude ranges (e.g., 37°-45°, 26°-37°, 13°-26°, 0°-13°) and corresponding recommended tilt angles.

Remote Control Guide

The range of the remote control to the indicator is 16ft (Day time) to 33ft (Night time). Because sunlight impacts the signal, it is recommended that users set up the mode before installing the light.

Remote Control Functions:

• 1. On/Off: When off is selected, the light stops working. The solar panel does not charge the battery, and the battery does not supply electricity to the light.
• 2. Connect/Test: The remote can connect to any lighting fixture one at a time. Press the button once to connect. It also functions as a test button. Pressing the "Test" button once shows a red light indicating charging or a green light indicating operation for 10 seconds, then returns to the previously used mode.
