Axpert Ultra-Max 11kW, PV12000
Categories: Inverter, IP21 HYBRID INVERTERS
The Triex Axpert Ultra-Max 11kW is a high-capacity hybrid solar inverter designed for large Pakistani homes, villas, and small commercial installations where power demand is high and load shedding disruption is not acceptable. With 11000VA of rated output, 22000VA of surge power, and 12000W of dual MPPT solar input, it handles the heaviest residential loads in Pakistan, including multiple inverter ACs, refrigerators, water pumps, and office equipment, all simultaneously and without compromise.
The Axpert Ultra-Max 11kW operates in hybrid mode, meaning it stays connected to K-Electric or WAPDA when available, uses solar to offset your electricity bill, charges the battery bank with excess solar energy, and switches seamlessly to battery backup when load shedding starts. The transfer time is 10ms for personal computers and 20ms for home appliances, so the transition is smooth and most devices never detect the switch.
With parallel capability for up to 6 units, the Axpert Ultra-Max 11kW can scale to 66kW of combined output for larger commercial or industrial applications. The built-in current transformer sensor and external BMS temperature sensor support give installers precise control over system behavior across large installations. AFCI detection, GFCI protection, and rapid shutdown compliance add a critical safety layer that is essential for any large solar installation.
For DHA, Clifton, Bahria Town, and other premium residential areas in Karachi and Lahore where households run 2 to 3 air conditioners and expect uninterrupted power, the Axpert Ultra-Max 11kW is the right inverter.
