This series of inverter power supplies stands out as a sophisticated double-conversion online system, designed for single-phase input and output, ensuring uninterrupted power supply. Boasting exceptional efficiency and reliability, it delivers top-notch AC power tailored to meet your equipment's demands. The compact 5~10KVA model excels with a high AC input power factor and supports parallel operation with two units, providing redundant power to bolster reliability. Ideal for critical infrastructure in sectors like electricity, telecommunications, mobile networks, Unicom, and railways, it ensures robust power backup.
Basic Operations: Adhere to the operational standards applicable to a standalone unit.
Parallel Power-Up: Once the mains power is connected, simply press and hold the start button on any one inverter. Both inverters will power up simultaneously and transition to inverter mode together. For battery power-up, individually long-press the power buttons on both inverters, enabling them to operate in battery inverter mode.
Parallel Shutdown: To achieve parallel shutdown, press and hold the shutdown button on any unit for more than 4 seconds (accompanied by two distinctive audio prompts). For individual power-off, press the power-off button on any unit for between 1 and 4 seconds (with an audio confirmation). Prior to shutting down the entire power supply, ensure the AC input is disconnected to deactivate the bypass circuit's output.
