4. Seadistamine ja installimine
Proper installation is crucial for the controller's performance and longevity.
4.1 Ühendusskeem
Follow the wiring sequence carefully to avoid damage.

Figure 3: Wiring diagram illustrating connections for the solar panel, battery, and load.
Juhtmete ühendamise etapid:
- Ühendage aku: Connect the battery's positive and negative terminals to the corresponding battery connection leads on the controller. Ensure correct polarity. The controller will automatically detect the system voltage (12V või 24V).
- Ühendage päikesepaneel: Connect the solar panel's positive and negative terminals to the corresponding solar panel connection leads on the controller. Ensure correct polarity.
- Ühendage koormus: Connect the load's positive and negative terminals to the corresponding load connection leads on the controller. Ensure correct polarity.
Tähtis: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load, then solar panel, then battery.
4.2 Paigaldamine
The controller should be mounted in a location that allows for adequate air circulation. Refer to the dimensions below for installation planning.
