Continuous operation and comfort, regardless of weather conditions

Invest in the future with the Qoltec 4000W solar inverter and enjoy energy independence. Thanks to the bypass function, it can be connected to both solar panels and the power grid, ensuring uninterrupted operation of the heating equipment. Thanks to this users can rest assured that their heating system will operate reliably under all conditions, with no interruptions in heat supply. Your home deserves the best!

Comfort and economy - modern heating for your home!

• Thanks to advanced MPPT technology, the inverter ensures maximum use of solar energy, resulting in lower electricity bills,
• It can be connected to both solar panels and the power grid, e.g. in the event of an energy shortage,
• Ideal for various heating applications, from heating water in boilers to supplying underfloor heating systems,
• Robust design and high quality workmanship guarantee long and trouble-free operation.

Get the most out of MPPT technology
Our inverter uses MPPT technology to maximise energy efficiency, enabling optimum use of solar energy. In this way, the system continuously monitors and adjusts the voltage and current of the photovoltaic panels, to ensure maximum power point. This is advanced energy management allows the highest possible efficiency to be achieved from solar panels, even under varying weather conditions such as partial shade or changes in the intensity of sunlight.

Solar energy in your heating system

• Thanks to its advanced MPPT technology and BYPASS function, the inverter is ideal for:
• Power supplies for electric boilers, enabling the heating of domestic water and electric heaters, providing warmth throughout the house,
• It will also work in heating mat systems, which are used in bathrooms, kitchens or other rooms requiring additional heating,
• Can be used for the supply of heating systems for swimming pools, allowing to maintain a comfortable water temperature in an ecological and economical manner,
• Solar energy can be used efficiently to maintain an optimum floor temperature, which increases occupant comfort and reduces heating costs.

Easy monitoring and configuration
The solar inverter is equipped with an advanced LCD display that provides users with full control and transparency of system operation. Intuitive display menu makes it easy to configure and customise inverter settings to suit individual user needs. The display shows the current operating parameters, allowing the performance of the system to be monitored on an ongoing basis. Users can quickly check the current operating status of the inverter, including the operating mode (MPPT, BYPASS) and information on any errors or alarms.

Your safety is our priority - advanced security technologies
The product is equipped with a number of safety features to ensure safe and reliable use:

• Overvoltage protection: Prevents damage caused by excessive voltage from photovoltaic panels or the power grid
• Short-circuit protection: Automatically disconnects the system if a short circuit is detected, protecting the equipment and the installation
• Protection against overheating: A built-in temperature monitoring system automatically switches off the inverter if the internal temperature exceeds a safe level
• Overload protection: Prevents damage caused by overloading, ensuring long-term, trouble-free operation of the equipment
• Protection against power failure: The BYPASS function automatically switches power to the grid in the event of a power failure from the PV panels, ensuring uninterrupted system operation.
