Product description
The Monolith voltage inverter by Qoltec MS wave is a device that converts 12V DC to 230V AC. It is ideal for places where there is no direct access to the power grid. It can easily power devices such as a laptop, computer, game console, kettle, or hairdryer, or charge your smartphone. The product has built-in sockets compatible with European plugs and a USB port.
- Device cooling is provided by a fan
- Soft start function
- Additional fuses included
Modified sine wave - simple design, less failure-prone
Devices that do not require a pure sine wave, such as LED power supplies, LED lighting, computer, laptop, small household appliances, will work without problems with a modified sine wave inverter, which produces an approximated AC voltage sine wave at the output, with an effective value equal to the sine wave value found in the power grid. This type of inverter primarily offers less failure-prone operation and a simple design.
Provide your devices with the right working conditions
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 consumption required by the connected device should not exceed 85% of the inverter's rated power.
Don't lose energy on the go
The product is ideal 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 being well-prepared. 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, featuring a USB port and sockets to which electrical devices can be connected. You can charge your phone, laptop, or connect another device whose power does not exceed the inverter's power, and you can also charge the battery simultaneously.
Depending on the power consumed by the device, the 1500W inverter can power devices such as:
- RTV equipment: TV, game console, music equipment, radio
- Household appliances: kettle, coffee maker, toaster, sandwich maker
- Office equipment: computers, printers, laptops
The inverter can also be used not only on the go but also as an emergency power source, e.g., to maintain power for equipment as a UPS during temporary power outages from the grid.
Durable and lightweight housing
The housing is designed from high-quality aluminum resistant to shocks and mechanical damage. It's an ideal choice for people who enjoy long journeys. With the inverter featuring a built-in socket, you can use almost any device that requires a plug connection. The product has a USB port for charging mobile devices and an automatic fan for proper cooling.
Full confidence in the quality of your device's power supply
The product is equipped with a range of protections that guarantee full protection for connected devices. Additionally, the set includes spare fuses to ensure the longest possible operation of the equipment.
- UVP — protects devices from too low output voltage, which affects the stability of connected devices,
- SCP — short-circuit protection
- OVP — protection against too high output voltage and damage to connected devices,
- OCP — protection against too high current on the line
- OTP — overheating protection
