ALLWEI 1500W Pure Sine Wave Inverter 12V DC to 110V/120V AC Converter, Surge 3000W | Power Inverters Vehicles with 2 AC Outlets, RV Truck Boat Home Outdoor & Off-Grid Solar Inverter, Smart LCD Display

What is the continuous power and peak power of this pure sine wave inverter?

1500W continuous power and 3000W peak power, capable of driving medium-sized appliances like refrigerators, microwaves, washing machines, and 1HP air conditioners.

What’s the advantage of the Pure Sine Wave Inverter? Is it suitable for sensitive devices?

Pure sine wave inverters' clean power minimizes electromagnetic interference (EMI ) and motor wear, extending lifespan of motor/compressor-driven appliances (e.g., fridges, ACs, pumps, drills).

What is the input voltage? Does it stabilize voltage fluctuations?

This inverters are suitable for 12 V Battery Banks ONLY. It converts DC 12V to 110V/120V AC, the common household power that charges and operates a widerange of electric appliances. It can auto-stabilizes voltage to protect devices from fluctuations

Will the fans run constantly, or do they turn off when not needed?

The dual-fan system intelligently monitors load & temp. Fans shift to high speed at ≥750W or ≥113°F for optimum cooling, run low at 250–750W or <113°F, and may shut off at <250W & <113°F to minimize noise.

How to sizing a Battery Bank?

Step 1: Sum the wattages of devices operating simultaneously (e.g., 2×60W lights+300W computer = 420W).

Step 2: Use (Wattage ÷ Battery Voltage) × Runtime (e.g., 750W microwave ÷ 12V × 4 hours = 250Ah battery).
