Qoltec Pure Sine Wave Inverter 12V to 230V 2000/4000W UPS BYPASS LCD USB USB-C Compatible with LiFePO4 GEL AGM

PURE SINE WAVE – POWER QUALITY JUST LIKE FROM THE SOCKET
Power all your devices without restrictions
The pure sine wave inverter generates a voltage identical to that of the mains supply, thereby ensuring full compatibility even with the most demanding devices. Thanks to advanced power conversion technology, Pure Sine Wave inverters are recommended wherever safety, stability and full hardware compatibility are essential.

- ideal for devices sensitive to power quality,

- safe for electronic equipment and motors,

- stable and quiet operation of devices,

- no interference or risk of damage,

- safe operation even under prolonged load.
Uninterrupted operation – UPS (BYPASS) mode
The inverter is equipped with a bypass (UPS) function, which is responsible for intelligent power source management:
- the bypass (UPS) function, i.e. automatic switching of the power source between the 230V mains and the 12V battery – without the need for user intervention

- when 230V mains voltage is available – the device switches to bypass mode

- in the event of a power failure – the system automatically switches to the 12V battery

- once power is restored, the inverter returns to bypass mode and resumes supplying power to the devices from the mains.

Compatibility with modern and traditional batteries
Compatibility with AGM, GEL and LiFePO4 batteries
The voltage converter has been designed to work with common types of 12V batteries, making it suitable for a wide range of power supply systems – from automotive installations to off-grid systems.
Match the battery to the inverter’s power rating
To ensure correct operation, the battery should supply a voltage within the range of approx. 10.5V – 15.5V DC and sufficient current to power the connected devices.

- the higher the inverter power, the greater the current demand

- the recommended minimum battery capacity ensures stable operation

- higher capacity = longer operating time for devices

Ensure your devices have the right operating conditions
Choose the right power rating, match the voltage, allow for a safety margin
When selecting the right power converter, it is worth paying attention to the power rating and voltage of the battery, which must match those specified on the converter to ensure our equipment operates under the right conditions. The number of connected devices is also important; for example, when connecting a laptop and a printer, the power of both devices must be added together. Remember that the power consumption of the connected device should not exceed 85% of the converter’s rated power.
Why is this so important?
✔ prevents overloads

✔ extends the device’s lifespan

✔ ensures a stable voltage for the connected equipment

✔ minimises the risk of shutdowns and performance drops
