2. Installation and System Connection
Follow these steps for proper installation. Ensure all connections are secure and correct to prevent damage to the controller or other components. Always connect the battery first.

Figure 2: System Connection Diagram.
- Connect Battery (1): Connect the battery to the charge controller first. Ensure correct polarity (+ to + and - to -). The controller will automatically detect 12V or 24V battery systems.
- Connect Solar Panels (2): Connect the solar panel(s) to the charge controller. Again, observe correct polarity.
- Connect DC Load (3 - Optional): Connect your DC loads (e.g., LED lights) to the controller's load terminals. Ensure correct polarity.
- Connect Inverter (4 - Optional): If using an inverter for AC loads, connect it to the battery terminals. The inverter should not be connected directly to the load terminals of the controller.
Важна напомена: Connect in strict accordance with the sequence: 1. Battery, 2. Solar Panel, 3. Load. Disassembly should be in the reverse order to prevent damage.
Монтажа:
- Mount the controller on a vertical surface to allow for proper heat dissipation.
- Ensure adequate clearance around the controller for air circulation.
- Avoid mounting in direct sunlight, high temperatures, or areas prone to water exposure.
3. Рад и подешавања
The controller features an LCD display and three buttons for navigation and parameter adjustment.

Figure 3: LCD Display and Button Functions.
- Дугме МЕНУ: Short press to switch between display interfaces. Long press (3-5 seconds) to enter or exit parameter setting mode.
- Дугме ГОРЕ: In parameter setting mode, press once to increase the parameter value.
- Дугме НАДОЛЕ/УКЉУЧЕНО/ИСКЉУЧЕНО: In parameter setting mode, press once to decrease the parameter value. In normal display mode, press to turn the load on or off.
The LCD displays various information including voltage, ampere-hour, load output status, battery status, and solar panel charging light indicators (On: Direct/Boost Charge; Slowly Flash: Float Charge).
3.2. Параметер Сеттингс
To adjust parameters, long press the МЕНУ button for 3-5 seconds to enter the setting interface. Use the UP и ДОВН buttons to modify values. Long press the МЕНУ button again to save and exit, or long press ДОВН to restore default parameters.

The common adjustable parameters include:
- Флоат Волtage: Волtage at which the battery is maintained after full charge.
- Поновно повезивање пражњењаtage: Волtage at which the load will reconnect after low voltagе искључење.
- Запремина заустављања пражњењаtage: Волtage at which the load will be disconnected to protect the battery from over-discharge.
- Режим рада: Configures how the load operates (e.g., 24 hours, dusk to dawn, timed).
- Тип батерије: Select the battery type (e.g., B01 for GEL, B02 for Sealed, B03 for Flood). This controller is only applicable to lead-acid batteries (Open type, VRLA, GEL, etc.).
4. Одржавање
Regular maintenance ensures optimal performance and longevity of your solar charge controller.
- чистоћа: Одржавајте контролер чистим и без прашине и прљавштине. Користите суву крпу за чишћење.
- Везе: Periodically check all wiring connections to ensure they are tight and free from corrosion. Loose connections can cause overheating and damage.
- вентилација: Ensure that the ventilation openings are not blocked to allow for proper heat dissipation.
- Услови животне средине: Verify that the controller is operating within its specified temperature and humidity ranges.
- Здравље батерије: Monitor your battery's health and voltage regularly. A healthy battery is crucial for the overall system performance.
5. Troubleshooting and Safety Protections
The Thlevel solar charge controller is equipped with multiple safety features to protect itself and your solar power system. Understanding these protections can help in basic troubleshooting.

Figure 5: Built-in Security Protections.
- Заштита од кратког споја: Automatically disconnects if a short circuit is detected in the load or solar panel circuit. Check wiring for shorts.
- Заштита од преоптерећења: Disconnects the load if the current exceeds the rated capacity (20A). Reduce the load or use a higher-rated controller.
- Прекострујна заштита: Similar to overload, protects against excessive current flow.
- Заштита од преоптерећења: Stops charging the battery once it reaches the set overcharge voltage, preventing damage.
- Ундер-волtagе Заштита: Disconnects the load when the battery voltagе пада испод подешене запреминеtage threshold, protecting the battery from deep discharge.
- Овер-волtagе Заштита: Protects the system from excessively high voltagе инпутс.
- Заштита од обрнутог поларитета: Protects the controller from damage if the battery or solar panel connections are reversed. However, always ensure correct polarity during installation.
Уобичајени проблеми:
- Нема дисплеја/Нема напајања: Check battery connections and ensure the battery has sufficient charge.
- Батерија се не пуни: Verify solar panel connections, ensure panels are receiving sunlight, and check for any shading. Confirm battery type setting is correct.
- Учитавање не ради: Check load connections, ensure the load is within the controller's current limits, and verify the load work mode settings. The battery might be too low (under-voltage protection activated).
