2. Varnostna navodila
- Ensure all electrical connections are made by qualified personnel.
- Ne poskušajte sami odpirati ali popravljati pretvornika. Obrnite se na pooblaščeno servisno osebje.
- Razsmernik namestite v dobro prezračevanem prostoru, stran od vnetljivih materialov in neposredne sončne svetlobe.
- Preverite pravilno voltage and current ratings for all connected components (solar panels, batteries, loads).
- Pred kakršnim koli vzdrževanjem ali ožičenjem vedno izklopite napajanje.

The WiFi module has a unique ID: 53566876275216755365 and MAC address: 74E9D81C1E1E.
4. Nastavitev in namestitev
4.1 Žične povezave
Carefully connect the solar panels, battery bank, AC input (grid), and AC output (loads) to the designated terminals on the inverter. Ensure all connections are secure and correctly polarized. Refer to the wiring diagram in Figure 3 for port locations.
4.2 Vzporedno delovanje
The DATOUBOSS 11KW Hybrid Solar Inverter supports parallel operation of up to 9 units to increase total power output. Follow the specific communication and power wiring diagrams provided in the full installation guide for multi-unit setups.

4.3 Začetna konfiguracija
Upon initial power-up, use the LCD and function keys to configure essential settings. This includes setting the input voltage range suitable for your household appliances or personal computers, and defining the AC/solar charger priority.
5. Načini delovanja
The inverter offers various operating modes to optimize power usage and battery charging.
5.1 načini polnjenja
There are four distinct charging modes available:
- Priority of the Mains Power Supply: If mains power is available, the battery is charged using solar energy.
- Prioriteta sončne energije: Charging with solar energy has priority. If no solar power is available, the battery is charged via the power grid.
- Mixed Loading: Solar and mains power can charge the battery at the same time.
- Samo sončna energija: The battery can only be recharged using solar energy.
5.2 Charge Output Working Modes
Three charge output working modes determine the power source priority for connected loads:
- Netz (Utility Priority): The mains current has priority over the load (default).
- Solar (Solar Priority): Solar power has priority, followed by battery, then grid power for the consumer.
- SBU (Solar-Battery-Utility): Solar power is prioritized, then battery. If battery voltage drops below a set point, the grid supplies power.

6. Vzdrževanje
- Redno čiščenje: Prezračevalne odprtine pretvornika naj bodo čiste od prahu in umazanije, da zagotovite pravilen pretok zraka in preprečite pregrevanje.
- Upravljanje baterije: The inverter's integrated features help manage battery charging and discharging cycles to prolong battery life. Ensure batteries are maintained according to their manufacturer's guidelines.
- Preverjanje povezave: Občasno preverite vse električne povezave glede tesnosti in znakov korozije.
- Posodobitve vdelane programske opreme: Preverite pri proizvajalcu webza morebitne razpoložljive posodobitve vdelane programske opreme za izboljšano delovanje ali nove funkcije.
7. Odpravljanje težav
The DATOUBOSS 11KW Hybrid Solar Inverter is equipped with comprehensive protection functions to ensure safe operation. If an issue arises, the LCD will display relevant indicators or error codes.
- Pogoste zaščite: Short-circuit protection, overcurrent protection, overvoltage zaščita, undervoltage protection, overheating protection, and overload protection.
- Brez izhodne moči: Check the main ON/OFF switch, battery connections, and AC output circuit breakers.
- Brez sončnega polnjenja: Verify solar panel connections, ensure sufficient sunlight, and check MPPT settings.
- Kode napak: Consult the detailed error code list in the complete product manual (if available) or contact customer support with the displayed code.
