5.2 Tatarajah Awal

• Sambungan Bateri: Connect the 48V battery bank to the inverter. Ensure correct polarity.
• Sambungan Input AC: Connect the 240V AC input source.
• Sambungan Output AC: Connect your 120V/240V split-phase loads to the inverter output.
• Pemilihan Jenis Bateri: Use the 8 pre-set battery type selector, including a de-sulphation option for flat batteries.
• Charge Current Adjustment: The maximum charge current can be adjusted from 0% to 100% via a linear switch. This is useful for matching the charger output to smaller capacity battery banks.
• AC Priority / Battery Priority: The inverter is designed with AC priority by default. When AC input is present, the battery charges first, and the inverter transfers the input AC to power the load. The AC Priority and Battery Priority switch (SW5) allows you to select battery priority, where the inverter will draw power from the battery even if AC input is available.
