Convertitore di tensione QOLTEC Monolith 4000 MS Wave 12V a 230V 2000/4000W con USB

The QOLTEC Monolith 4000 MS Wave is a 12V to 230V power inverter that provides a continuous output of 2000 W and a peak output of 4000 W, suitable for converting vehicle or battery DC power into mains-grade AC. Designed for automotive and off-grid scenarios, this inverter produces a modified sine wave output and includes integrated USB ports for charging phones and small devices. It is intended for temporary AC supply to household appliances, power tools and electronic equipment where mains connection is not available.

Advantages

The inverter supports high continuous and surge power levels that allow operation of a range of appliances and tools. Its 12V input compatibility makes it suitable for use with car batteries, leisure vehicle electrical systems and standalone 12V battery banks. Built-in USB ports enable simultaneous charging of mobile devices without occupying AC outlets. Compact design and durable housing provide straightforward installation and reliable performance in mobile and temporary installations.

Suitable for

• Powering small to medium household appliances (kettles, microwaves, fans) within the device power limits
• Running power tools and workshop equipment for temporary jobs on-site
• Supplying AC power to laptops, chargers and consumer electronics during travel or outdoor activities
• Backup power for critical devices during short grid outages

Key specifications

• Input voltage: 12 V DC
• Continuous AC output: 2000 W
• Peak/surge AC output: 4000 W
• Output voltage: 230 V AC
• Output waveform: modified sine wave
• Integrated USB charging ports for mobile devices
• Cooling: built-in fan cooling
• Protection features: overload, over-temperature and low-voltage shutdown (functional protections)

How to use

Connect the inverter to a suitable 12V DC source such as a vehicle battery or a dedicated 12V battery bank, observing correct polarity. Place the inverter on a stable, ventilated surface and ensure clearance for airflow around the cooling fan. Plug AC devices into the 230V outlets and connect USB devices to the USB ports as needed. Monitor the inverter load to avoid exceeding the continuous or peak power ratings. If the inverter includes status indicators, use them to confirm proper operation and to identify protective shutdowns.

Recommendations

Use the QOLTEC Monolith 4000 MS Wave with appliances and tools whose starting and running power requirements are within the inverter's specified continuous and peak limits. Avoid prolonged operation near the maximum continuous load to reduce heat buildup. Ensure battery capacity and vehicle alternator output are sufficient for the intended run time, and follow standard safety precautions for DC connections, ventilation and grounding where applicable.
