4. Varnostna navodila
Med namestitvijo in delovanjem upoštevajte naslednje varnostne ukrepe:
- Ensure all connections are correct and secure before powering on the system.
- Connect the battery first, then the solar panel, and finally the DC load. Disconnect in the reverse order.
- Do not connect the solar panel to the controller without a battery connected.
- Krmilnik namestite v dobro prezračenem prostoru, stran od neposredne sončne svetlobe, visokih temperatur in vlage.
- Za vse povezave uporabite ustrezne premere žic, da preprečite pregrevanje in izgubo moči.
- Ta naprava je samo za uporabo v zaprtih prostorih.
- Hraniti izven dosega otrok.
5. Nastavitev in namestitev
5.1 Namestitev krmilnika
Mount the solar charge controller vertically on a flat, non-flammable surface. Ensure there is adequate airflow around the unit for proper heat dissipation. Avoid mounting near flammable materials or in areas with excessive dust or moisture.
5.2 Žične povezave
Follow the connection order carefully to prevent damage to the controller or other components. Always connect the battery first, then the solar panel, and finally the DC load.
- Priključite baterijo: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the controller. Ensure correct polarity. The controller will automatically detect the system voltage (12 V ali 24 V).
- Povežite sončno ploščo: Connect the positive and negative terminals of the solar panel to the corresponding solar panel terminals on the controller. Ensure correct polarity.
- Connect the DC Load: Connect the positive and negative terminals of your DC load to the corresponding load terminals on the controller. Ensure correct polarity.
Important: Disconnect components in the reverse order: Load, then Solar Panel, then Battery.

7. Vzdrževanje
Redno vzdrževanje zagotavlja dolgo življenjsko dobo in optimalno delovanje vašega solarnega regulatorja polnjenja:
- Preverite povezave: Občasno preverite vse ožičene povezave, da se prepričate, da so tesne in brez korozije.
- Očistite krmilnik: Krmilnik naj bo čist in brez prahu ter umazanije. Za čiščenje uporabljajte suho krpo. Ne uporabljajte tekočin.
- Preverite glede poškodb: Preverite morebitne fizične poškodbe casing or wiring.
- Prezračevanje: Prepričajte se, da prezračevalne odprtine niso blokirane, da se zagotovi pravilno odvajanje toplote.
8. Odpravljanje težav
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Controller not powering on / LCD blank | Baterija ni priključena ali je nizkatage; reverse polarity connection. | Ensure battery is connected first with correct polarity and has sufficient charge. |
| Baterija se ne polni | Solar panel not connected; insufficient sunlight; faulty solar panel/wiring; battery full. | Check solar panel connections and sunlight exposure. Verify solar panel functionality. The controller stops charging when the battery is full. |
| Obremenitev ne deluje | Load disconnected; battery voltage too low; overload protection activated; load control setting. | Check load connections. Charge battery. Reduce load. Adjust load control settings. |
| Prikazana je koda napake | Specific system fault (e.g., overvoltagnpr. kratek stik). | Refer to the controller's display for the specific error code and consult the manufacturer's support for detailed resolution. Address the underlying issue (e.g., disconnect short circuit). |
