Description
Direct photovoltaic heating for small to medium systems
SOL•THOR
Flexible photovoltaic power diverter for small to medium PV systems
SOL•THOR is a 0 - 3 kW linearly controlled photovoltaic power diverter designed for small to medium PV systems from 1 to 10 modules, offering maximum flexibility for hot water heating.
Simple & versatile: SOL•THOR works with existing heating elements in hot water storage tanks or electric boilers, making it perfect for retrofitting existing systems. Unlike other solutions, SOL•THOR doesn't include an integrated heating element, providing compatibility with your current setup while maximizing solar energy utilization.
The SOL•THOR features proven hot water backup functionality - even when there isn't enough sunlight, hot water can be heated to the desired temperature using grid electricity. This allows you to completely switch off conventional heating systems during summer, increasing system lifespan while being environmentally friendly and cost-effective.

Flexible solutions for every heating scenario
SOL•THOR with heating element in heat storage
The simplest way to retrofit for ecological and economical heat in single-family homes, multi-family houses, or autonomous applications.
The SOL•THOR linearly controls heating elements and uses the entire output of the photovoltaic modules for heat generation. Existing heating elements can be used, or a my-PV screw-in heating element can be integrated into the existing hot water or buffer storage.
The cables from the PV modules are plugged directly into the SOL•THOR via MC4 connectors, and the new or already installed heating element in the heat storage is connected to the SOL•THOR – that's how simple photovoltaic heating is.
SOL•THOR with electric boiler or wall-mounted storage heater
Conventional electric boilers become photovoltaic-compatible through SOL•THOR's linear regulation.
In addition to using the my-PV screw-in heating element, conventional electric boilers can also be controlled by the SOL•THOR. This means that electric boilers become compatible with photovoltaic systems through the linear regulation of my-PV's DC power manager, maximizing heat yield from photovoltaic power.
For autonomous use of photovoltaic power for heating with an electric boiler or wall-mounted storage heater, the cables from the PV modules are connected directly to the SOL•THOR via MC4 connectors. The conventional electric boiler is connected to the SOL•THOR, and the integrated heating element is regulated by the my-PV DC power manager according to the photovoltaic output.
SOL•THOR in combination with dynamic electricity tariffs
On days with low sunlight, the SOL•THOR can utilize cheaper electricity from the public grid for heating supply.
Anyone with a photovoltaic system and a dynamic electricity tariff can use the my-PV DTO to access cheap energy from the grid for heating even on cloudy days or at night when the PV system doesn't provide enough electricity. The my-PV DTO is easily activated in the my-PV Cloud and controls heating automatically – based on the lowest market electricity prices.
The my-PV DTO works in combination with all IoT-capable my-PV devices.
Frequently Asked Questions
Everything you need to know about SOL•THOR
The SOL•THOR can be flexibly used with a PV system ranging from 1 to 10 PV modules . Even the smallest photovoltaic systems are suitable for generating heat from photovoltaic electricity with the SOL•THOR.
Unlike the ELWA, which can be used with 4 to 8 modules, the SOL•THOR offers greater flexibility for your specific application with its broader scaling. Additionally, the SOL•THOR does not come with an integrated heating element, making it compatible with existing heating elements in a hot water storage tank or an electric boiler.
An Excel document provided by us offers assistance with sizing, allowing you to precisely enter the data of the PV module and check whether the number, etc., is compatible with the SOL•THOR.
Download Sizing DocumentThe SOL•THOR features our proven optional hot water backup function : Even if there isn't enough sunlight, the hot water can be heated to the desired temperature using energy from the public power grid.
This allows you to completely switch off the conventional heating system in the summer. This increases the lifespan of the heating system, is environmentally friendly, and saves money.

Which heating rod fits the SOL•THOR? That's easily answered with the my-PV 3 kW screw-in heating element .
The SOL•THOR regulates the heating rod - depending on the yield from the photovoltaic system - continuously from 0 up to 3,000 watts, thereby maximizing the utilization of photovoltaic heat. The 3 kW screw-in heating element from my-PV can be used in both fresh water and buffer tanks, offering maximum flexibility for applications in hot water or heating systems.
Key Features:
- Continuous 0-3,000W regulation
- Fresh water and buffer tank compatibility
- Easy screw-in installation
Cover 50% of your annual hot water needs
Just three conventional photovoltaic modules can make a significant difference
Half of your hot water needs covered
Cover half of your annual hot water needs with just three conventional photovoltaic modules: this is possible with the SOL•THOR.
If you have space on your balcony, garage, or roof, you can easily produce 50% of your hot water using solar power with the SOL•THOR.
The space available next to an existing balcony power plant (grey modules) can be efficiently used with DC standard modules (in green) for heating with the SOL•THOR. Heat from photovoltaic energy – good for the environment and your wallet.
