The Crown Micro Xavier 4KW MPPT Solar Inverter is an advanced off-grid/hybrid power management unit engineered to convert direct current (DC) generated by solar panels and stored in battery banks into clean 230V pure sine wave alternating current (AC). Operating with a Unity Power Factor (PF = 1.0), this 4,000W inverter ensures that 100% of its rated capacity is available as real output power without derating.
Tailored to solve load shedding challenges across urban and rural Bangladesh, the Xavier 4KW combines a high-efficiency MPPT solar charge controller, a multi-stage AC battery charger, and a rapid auto-transfer switch in a single compact chassis. Whether powering an urban apartment, corporate workstation, or retail setup, it optimizes solar self-consumption while maintaining uninterrupted power backup.

Reduces Electricity Cost: Maximizes daytime solar harvesting to lower monthly utility power bills.
Improves Operational Reliability: Keeps essential appliances and office equipment running smoothly without unexpected restarts during blackouts.
Saves Maintenance Cost: Built-in battery equalization and anti-dust protection extend system and battery lifespan.
Suitable for Bangladesh Environment: Specifically designed to manage local line voltage fluctuations, high temperatures, and humidity.
Must be installed by a certified electrician or qualified solar power engineer.
Mount vertically on a solid, non-combustible wall in a cool, dry, and well-ventilated area.
Maintain at least 20 cm clearance on all sides to allow proper airflow through the cooling fans.
Use correctly sized DC cables, AC circuit breakers, DC MCBs, and proper safety earthing ground.
Periodically clean dust from ventilation grills and fan covers using a soft, dry brush.
Inspect AC and DC terminal screws annually to ensure tight and corrosion-free connections.
Monitor operational metrics and battery charging status regularly on the front LCD screen.
Never open the inverter chassis while connected to PV arrays, batteries, or AC utility lines; dangerous high voltage exists internally.
Switch off external AC breakers, DC battery switches, and PV isolators before performing physical inspections.
Do not bypass protective breakers or operate the inverter with damaged wiring.
