5. Instruccions de funcionament
The Mass Combi Pro features a user-friendly control panel for basic operation and status monitoring.
5.1 Tauler de control acabatview
Refer to the product image in Section 3 for visual reference of the control panel.
- On/Off/Inverter Off Switch: This switch controls the main power and inverter function.
- A: Activates both the inverter and charger functions.
- Apagat: Turns off the entire unit.
- Inverter Off: Disables the inverter function while allowing the charger to remain active (if AC input is present).
- Llums indicadores: These LEDs provide status information:
- Gen: Indicates generator AC input is active.
- Principals: Indicates shore power AC input is active.
- Out 1 / Out 2: Indica l'estat de la sortida de CA.
- Float / Abs / Bulk: Indicate the current stage of the battery charging process.
5.2 Funcionament bàsic
- Inici de la unitat: Set the On/Off/Inverter Off switch to 'On'. The unit will perform a self-test, and the inverter will begin supplying AC power from the batteries if no external AC input is present.
- Càrrega de bateries: When an external AC source (shore power or generator) is connected and active, the unit will automatically begin charging the batteries according to the detected charge stage (Bulk, Absorption, Float).
- Switching AC Sources: The unit automatically switches between available AC input sources (generator, mains) and inverter power to ensure continuous AC supply to your loads.
- Apagant: To turn off the unit, set the On/Off/Inverter Off switch to 'Off'.
