Product description
The Qoltec inverter is a device that converts 24V DC to 230V AC. It is ideal for places lacking direct access to the power grid. The product has built-in sockets compatible with European plugs and a USB port.
- Pure sine wave — safe for any device
- Soft start function — safe start of engines and compression
- Includes spare fuses and a set of cables
Voltage inverter means mobile energy in a pure form
The Qoltec inverter is a pure sine wave, generating current the same as in a 230V socket, ensuring safety for all connected devices. It is perfect for power outages and during travel when there is no access to a socket.
When choosing the right inverter, it is worth paying attention to the power value and battery voltage, which must match the one specified on the inverter to provide our equipment with the right working conditions. The number of connected devices is also important, e.g., when connecting a laptop and printer, the power of both devices should be summed. Remember that the power consumed by the connected device should not exceed 85% of the inverter's rated power.
Don't lose energy while traveling
The product is perfect as a power source in campers or trailers during family trips. Planning a longer vacation at a campsite or by the lake and looking for a way to connect a laptop or charge a phone on a yacht? It's worth preparing well. Thanks to the Qoltec inverter, you will be able to power your devices anywhere and enjoy convenience and comfort.
The voltage inverter will be an ideal power source for yacht and boat owners. This intelligent device will allow you to power equipment during long trips away from home, with a USB port and sockets to connect electrical devices. You can charge your phone, laptop, or connect another device whose power does not exceed the inverter's power without any obstacles.
Depending on the power consumed by the device, the inverter can power:
- RTV equipment: TV, game console, music equipment, radio
- Household appliances: refrigerator, freezer, kettle, microwave, coffee maker, toaster, sandwich maker
- Office equipment: computers, printers, laptops
- Others: power tools e.g., drill, hairdryer, boat charging, CO furnace maintenance, air conditioning
The inverter can also be used not only during travel but also as an emergency power source, e.g., CO furnace maintenance or to power equipment as a UPS during temporary power outages from the power grid.
Durable and lightweight housing
The housing is designed with high-quality aluminum resistant to shocks and mechanical damage. It's an ideal choice for people who like long journeys. With the inverter with a built-in socket, you can use almost any device requiring a socket connection. Additionally, the product has a USB port for charging mobile devices and a fan ensuring proper cooling.
Full confidence in the quality of powering your devices
The product is equipped with a range of protections that guarantee full protection for connected devices. Additionally, the set includes a spare fuse to ensure the longest possible operation of the equipment.
The inverter has:
- UVP protection - protects devices from too low output voltage, which affects the stability of connected devices
- SCP protection - is short-circuit protection
- OVP protection - is protection against too high output voltage and damage to connected devices
- OCP protection - is protection against too high current on the line
- OTP protection - is protection against overheating
