Product information

Description

The Qoltec Pure Sine Wave Power Inverter is a high-performance device designed to convert 12V DC battery power into stable 230V AC electricity. With a continuous power output of 2000W and a peak capacity of 4000W, it provides reliable energy for a wide range of sensitive electronic devices. The unit features an integrated UPS bypass function, ensuring seamless power transition during outages, and includes an informative LCD display for real-time monitoring. Equipped with both USB and USB-C ports, it offers versatile charging options for modern mobile devices, while its advanced compatibility with LiFePO4, GEL, and AGM batteries makes it a flexible choice for various energy storage setups.

Advantages

This inverter stands out due to its pure sine wave output, which mimics the quality of grid electricity, preventing damage to delicate electronics such as laptops, medical equipment, or audio systems. The inclusion of a UPS bypass mode allows the device to function as an emergency power supply, automatically switching to battery power when the main grid fails. The robust construction supports multiple battery chemistries, allowing users to optimize their off-grid or mobile power systems. Furthermore, the built-in LCD screen provides clear visibility of operating parameters, while the dedicated USB and USB-C ports eliminate the need for additional adapters when charging smartphones or tablets.

Suitable for

  • Off-grid solar power installations
  • Emergency backup power systems for homes
  • Powering sensitive electronics in recreational vehicles and campers
  • Mobile workstations requiring stable AC power
  • Charging modern mobile devices via USB and USB-C

When it may not be suitable

This inverter is not designed for high-load industrial machinery that exceeds its 2000W continuous power rating. Additionally, it is intended for use with 12V battery systems and cannot be connected directly to 24V or 48V battery banks without appropriate voltage conversion equipment.

Key specifications

  • Input voltage: 12V DC
  • Output voltage: 230V AC
  • Continuous power: 2000W
  • Peak power: 4000W
  • Waveform: Pure sine wave
  • Battery compatibility: LiFePO4, GEL, AGM
  • Connectivity: USB, USB-C, AC outlets
  • Features: UPS bypass, LCD display

How to use

To operate the inverter, connect the input terminals securely to a compatible 12V battery bank, ensuring correct polarity. Once connected, switch the device on and monitor the LCD display to verify the input voltage and system status. Plug your 230V appliances into the AC outlets on the front panel. If using the UPS bypass function, connect the device to a standard wall outlet to allow the inverter to monitor grid power and switch automatically during a blackout. Always ensure the total power consumption of connected devices remains within the 2000W continuous limit.

What to consider before purchase

  • Verify that your battery bank is 12V and capable of handling the required discharge current.
  • Ensure the total wattage of your appliances does not exceed 2000W.
  • Check the cable thickness to ensure it is sufficient for the high current draw at 2000W.
  • Confirm that the installation area is well-ventilated to prevent overheating.
Usage recommendations: For optimal performance and safety, always install the inverter in a dry, dust-free environment with adequate airflow. Periodically inspect battery connections for tightness and corrosion to maintain efficient power transfer.
