Common Questions
What warranty does the DELTA Pro Ultra carry in Malaysia?
24 months on the unit and 60 months on the battery, honoured in Malaysia by the authorised distributor. Register the serial number once and the cover is on record before you need it.
What is the DELTA Pro Ultra's battery capacity?
102.4V⎓60A, 6,144Wh. Capacity is the figure that decides how long it runs a given load, so it is the first number to check against what you intend to power.
What can the DELTA Pro Ultra run?
Its AC output is rated US: 120/240V～60Hz 7200W total, 120V～20A (×4) Max per port, 120V～30A (×1), 240V～30A (×1) EU: 230V～50Hz 6900W total, 16A (×4) Max per port, 30A (x1) Max UK: 230V～50Hz 6900W total, 13A (×4) Max per port, 30A (x1) Max AU: 230V～50Hz 6900W total, 15A (×5) Max per port That rating, not the capacity, is what decides whether an appliance will start at all.
How heavy is the DELTA Pro Ultra?
Approx. 32.1 kg (approx. 70.8 lb). Worth knowing before you plan to carry it — weight is the specification most often discovered after delivery.
How long will the DELTA Pro Ultra's battery last?
The battery maintains 80%+ SOH (state of health) after 3,500 cycles at 0.5C/0.5C at 25°C (77°F) A cycle is one full charge and discharge, so normal household use reaches that figure over years, not months.
Where do I get the DELTA Pro Ultra serviced in Malaysia?
Through us. Faults are assessed here rather than shipped overseas — open a case and you get a case number, an assessment target and somewhere to track it.
