5.1 Kontrollpanelen överview
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.
- På: Aktiverar både växelriktar- och laddningsfunktionerna.
- Av: Turns off the entire unit.
- Inverter Off: Disables the inverter function while allowing the charger to remain active (if AC input is present).
- Indikatorlampor: These LEDs provide status information:
- Gen: Indicates generator AC input is active.
- Elnät: Indicates shore power AC input is active.
- Out 1 / Out 2: Indikerar AC-utgångsstatus.
- Float / Abs / Bulk: Indicate the current stage of the battery charging process.
5.2 Grundläggande användning
- Starta enheten: 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.
- Ladda batterier: 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.
- Stänger ner: To turn off the unit, set the On/Off/Inverter Off switch to 'Off'.
