Frequently Asked Questions - SOL10UC3 Perel

What type of battery can be used with the SOL10UC3?

The controller supports sealed lead-acid, gel and flooded (open) batteries. The type is selected by holding the setting button for 5 seconds then pressing to choose.

How to connect the controller correctly?

First connect the battery (the battery LEDs should light up green), then the load (e.g., lamp), and finally the solar panel. Respect polarities and use recommended fuses.

What does rapid flashing of the charge LED mean?

Rapid flashing of the charge LED indicates a short-circuit. The controller attempts to reset automatically after 10 seconds; if the fault persists, press the setting button once.

How to set the battery type?

Hold the setting button for 5 seconds until LEDs 1 to 3 flash. Then press briefly to scroll through types: only LED1 = sealed, LED1+2 = gel, LED1+2+3 = flooded. The setting is saved when the LEDs stop flashing.

Why is the battery LED flashing slowly?

Slow flashing of the battery LED (LED1) indicates undervoltage (voltage too low). Check the battery voltage and recharge if necessary.

How to clean the controller?

Occasionally clean the device with a damp cloth. Do not use aggressive chemicals, solvents, or strong detergents.

Can the controller be used with a 24V battery?

Yes, the SOL10UC3 accepts 12V and 24V systems. The voltage parameters (thresholds) are doubled for a 24V system, as indicated in the manual.

What to do if the charge LED does not light up while the panel is in sunlight?

First check that the panel input voltage is higher than the battery voltage. Also ensure that the battery voltage is above 6V (minimum startup voltage) and that cables are properly connected.

Is it possible to repair the controller yourself?

No, there are no user-serviceable parts. Never open the case due to risk of electric shock. Any repair must be done by a qualified technician.

How to activate the USB output?

The USB output is automatically activated when the controller is powered on (i.e., when the battery is connected and the panel supplies energy). No additional manipulation is needed.

2. Safety Instructions

- This device can be used by children aged from 8 years and above, and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning the use of the device in a safe way and understand the hazards involved. Children shall not play with the device. Cleaning and user maintenance shall not be made by children without supervision.

- There are no user-serviceable parts inside the device. Refer to an authorized dealer for service and/or spare parts.

- Risk of electroshock when opening the cover. Touching live wires can cause life-threatening electroshocks. Do not disassemble or open the housing yourself. Have the device repaired by qualified personnel.

- As soon as a solar panel is exposed to (sun)light, the terminals will be live. To avoid short-circuits when assembling and connecting, turn them away from the light or cover them so that they are not producing electricity. Remove the covering once all connections have been made.

- Do not allow water to enter the device.

SOL10UC3

• Always mount the solar panel on a straight and flat surface. Do not bend or twist the panel.
• Never attempt to divide or disassemble the panel.
• Avoid drilling or welding the frame whenever possible.
• Do not use sharp metal tools or any other tools that can scratch the surface of the panel.
• Install the solar panel horizontally or vertically. The solar panel should be facing south at an angle of 0-20°. Bear in mind that if the solar panel is cast in shadow, its power output will drop considerably. Choose a location for the panel with as little shade as possible.

Mounting

• Be careful when working with batteries. Wear eye protection and have clean water ready to clean any contact with battery acid.
  • Use insulated tools and avoid placing metal objects near the battery.
• Install the battery in a well-ventilated room away from direct sunlight and moisture.
• Make sure the solar panel and/or fuses near the battery are disconnected prior installation.
• The installation requires fuses/breakers (not included).
  • Make sure all connection are properly tightened and free from corrosion.

Connect the components to the charge regulator in the sequence shown as above. Pay attention to the positive and negative poles.

1. Connect the battery first. Check if the battery indicator turns green. If not, refer to chapter Troubleshooting.
2. Next, connect the load, e.g. a lamp. The load should be DC applicant with the same rated voltage as the battery's.
3. Finally, connect the solar panel.

8. Troubleshooting

- The solar panel is exposed properly to sunshine but the charging LED is off.

• The input voltage of the solar panel is lower than the battery voltage. Check the input voltage of the solar panel.
• The battery voltage is lower than 6 V. The minimum start-up voltage is 6 V.
  ○ Disconnected wiring. Check if the wiring is connected properly.

- The charging LED is flashing rapidly.

○ Battery voltage exceeds the overvoltage disconnect (OVD) values.

Disconnect the solar panel and check the battery voltage.

• LED1 is flashing slowly/rapidly.
○ Battery voltage too low/discharged. Check the battery voltage.
- The load status LED is flashing slowly.
- Overload. Reduce the load and press the setting button once.
- The load status LED is flashing rapidly.
○ Short-circuit. The regulator automatically resumes after 10 seconds. When a second short-circuit occurs, press the setting button once.
