Three functions in one device – inverter, charger and UPS The Qoltec pure sine wave inverter combines three devices in a single compact housing. It is an ideal solution for the home, office, workshop, motorhome, boat or as an emergency power source during mains outages. 12 V → 230 V inverter – when powered by a battery, it supplies 230 V AC to connected devices. Battery charger – when connected to the mains, it automatically switches to battery charging mode. UPS – uninterruptible power supply – in the event of a power failure, it switches to battery power until the mains is restored. The inverter can charge the battery and power connected devices at the same time, providing maximum flexibility and comfort. Pure sine wave for sensitive equipment The Qoltec inverter generates a pure sine wave that is the same as the 230 V mains supply. This ensures safe operation not only for simple devices, but also for sensitive electronics and equipment with electric motors. Rated power: 300 W – for everyday use. Peak power: 600 W (5 s) – for short start-up current surges. Input: 12 V (battery) / 190–260 V AC (for charging). Output: 230 V / 50 Hz with efficiency up to 90%. When connecting, for example, a laptop and a printer, their power consumption must be added, and the total load should not exceed around 85% of the inverter’s rated power to ensure safe and long-lasting operation. Don’t lose power while travelling This inverter is perfect for motorhomes, trailers, yachts and boats, as well as longer trips and camping. It provides convenient access to a 230 V socket anywhere a 12 V battery is available. The inverter features a USB port for mobile devices and AC outlets for other electrical equipment. Devices up to about 150 W (e.g. smartphone, laptop) can also be powered from a cigarette lighter socket. The 300 W inverter can supply power to RTV, office and household appliances – TVs, game consoles, audio systems, computers, a refrigerator and light power tools, provided the power limits are observed. Durable and lightweight aluminium housing The inverter housing is made of high-quality aluminium, which is resistant to impacts and mechanical damage. It is ideal for use on the move – in a car, motorhome or workshop. The built-in fan and intelligent cooling system ensure optimal operating temperature and extend the service life of the device. In addition, the inverter offers a 5 V / 1 A USB output for mobile devices. Full protection and safe operation The product is equipped with multiple protection features that safeguard both the inverter and the connected devices. The package also includes a spare fuse to ensure long-term and safe operation. LVP/UVP – protection against low input voltage. OVP – protection against excessive output voltage. OCP – protection against overload and overcurrent. SCP – short-circuit protection. OTP – over-temperature protection. Reverse polarity protection – via fuse. Do not cover the ventilation openings and always observe correct wiring and polarity. The inverter is also equipped with a soft-start function, which reduces inrush current and protects connected equipment during start-up. Reliability confirmed by warranty If product quality and reliability are important to you, the Qoltec inverter is a solid investment. It comes with a 24-month warranty from the date of purchase, confirming the manufacturer’s confidence in the durability and safe operation of the device.
