my-PV SOL-THOR DC Power Manager up to 3.6 kW for photovoltaic heating

The SOL-THOR from my-PV (MPN: 14-0100) is a continuously adjustable DC power manager that efficiently converts solar power into heat. The direct current from your panels is transmitted almost loss-free directly to a connected heating element, ensuring maximum efficiency. Thanks to its self-sufficient operation, it requires no connection to the utility grid and is fully powered by your 1–10 PV modules. If you need additional heat, the SOL-THOR can automatically switch to grid power and provide supplemental heating. You can use both new and existing heating elements in your heat storage tank. This makes retrofitting a heating system simple and cost-effective. Furthermore, no approval from the grid operator is required, and because it uses cables instead of pipes, the system is maintenance-free. In off-grid applications, the SOL-THOR can operate in frequency mode. It is compatible with leading brands such as Victron Energy, Growatt, Huawei, Studer, and SMA.

Product Highlights

• Max. Power: 0–3.6 kW, continuously adjustable
• No inverter required
• For PV systems with 1–10 modules
• Frequency mode in off-grid applications
• Lossless conversion of all solar power into heat
• More cost-effective than conventional water heating
• Works just as well during power outages or grid failures
• Optional hot water backup

Flexible heat generation without additional effort

Thanks to its self-sufficient operation, no connection to the power grid is required. The SOL-THOR powers itself directly from your PV generator, eliminating the need for grid feed-in, inverters, and connection permits. This DC power manager efficiently and directly uses the solar power from your solar panels to generate heat. The system can be operated with 1–10 PV panels. It transmits the direct current from your panels directly to a heating element and converts it into heat. Two heating elements can be controlled alternately to optimally adjust heat generation. On a day with little sunshine, it automatically switches to grid power so you always have hot water. It doesn’t get any simpler—more flexibility and reliability for your solar supply.

Your advantages over solar thermal systems

• Install only electrical cables instead of complicated piping
• Virtually no losses between the PV generator and the heat storage tank
• No moving parts and no need for frost protection monitoring—maintenance-free
• PV modules actually deliver a higher yield at low ambient temperatures
• The system restarts automatically and ensures that your heat supply remains uninterrupted

Easy installation with a heating element in the heat storage tank

Installation is a breeze—simply connect the cables from your PV modules directly to the SOL-THOR using MC4 connectors. The heating element in the heat storage tank, whether new or already installed, is also easily connected to the Power Manager. If your PV output is ever insufficient due to bad weather, you can optionally supplement it with electricity from the public grid.

Maximum heat output with an electric water heater or wall-mounted storage tank

The SOL-THOR makes not only the my-PV screw-in heating element but also conventional electric boilers compatible with solar power. For self-sufficient operation, simply connect the cables from your PV modules directly via MC4 connectors. The electric boiler is also connected to the Power Manager, so that the integrated heating element is optimally regulated based on solar output. Of course, even on days with little sunshine, you remain flexible with grid power.

Applications

Single-family home— The simplest retrofit solution. It provides stepless control of heating elements and is also compatible with conventional electric water heaters.
Residential Buildings— In multi-unit buildings, grid-connected PV systems are often too complicated. The Power Manager offers the ideal solution for supplying each apartment separately—even with conventional electric water heaters.
Other Applications— It’s perfect for projects requiring hot water in rural or off-grid settings.
