my-PV AC-THOR 9s PV power manager up to 9kW for hot water

The AC-THOR 9s from my-PV (MPN: 20-0300) is a continuously adjustable PV power manager with an output of up to 9 kW. Unlike the AC-THOR, it efficiently controls up to three of your electric heat sources and regulates them based on the availability of PV energy and your heating needs. It ensures living comfort fully automatically, whether for hot water or heated rooms. In modern or renovated residential buildings, the AC-THOR 9s can replace conventional, water-based home heating systems or be integrated into existing systems, such as buffer tanks. Any shortfall in energy is covered by the utility grid. Thanks to its touchscreen display, it’s easy to operate at any time and a breeze to install. The my-PV Cloud is available to help you keep an eye on everything and respond as needed. In off-grid applications, the AC-THOR 9s can operate in frequency mode. It’s compatible with brands such as Victron Energy, Growatt, Huawei, Studer, and SMA.

The AC-THOR 9s Takes Center Stage

• Continuously adjustable up to 9 kW, instead of 3 kW with the AC-THOR
• 3 adjustable outputs
• Frequency mode for off-grid applications
• For 3-phase heating elements with a common neutral conductor
• 30% cost savings compared to conventional systems
• Two-zone room heating possible
• Can be combined with a heat pump
• Everything at a glance—thanks to my-PV Cloud
• Integrated touchscreen

Better than conventional heat generators

For PV systems with capacities ranging from 5 to 10 kWp, the AC-THOR 9s achieves annual performance factors that are significantly higher than typical values. This makes electric space heating economically attractive. It relies on cables instead of pipes and electricity instead of hydraulic systems, while remaining simple and straightforward. Unlike heat pumps, you can significantly influence investment and operating costs by sizing your PV system appropriately. Savings of up to 30% are easily achievable.

Versatile Applications

• Pure photovoltaic water heating up to 9 kW
• Can be combined with a wide variety of battery storage systems
• Extremely simple charging of three zones—3 x 3 kW
• Hot water and two-zone space heating
• Standard heat pump becomes PV-compatible

System for 3-phase heating elements up to 9 kW— The AC-THOR 9s offers the same compact design as the AC-THOR and can simultaneously provide stepless control of 3-phase heating elements with a power output of up to 9,000 watts. More power and flexibility for your heating system! Thanks to plug-in connections, installation is a breeze. You can commission the Power Manager quickly and easily and immediately enjoy the benefits of its high efficiency.

System for three single-phase heating elements— It’s ideal for charging large thermal storage tanks. It continuously regulates up to three heating elements in sequence, ensuring you have hot water available quickly. If the excess power exceeds 3,000 watts, the AC-THOR 9s combines the control of the heating elements. This maximizes self-consumption and significantly shortens the charging time.

System for Hot Water and Space Heating— This feature not only ensures efficient hot water production but also controls your electric space heating continuously and in a photovoltaic-compatible manner. In addition to controlling heating elements, it can supply two heating circuits and regulate them independently of one another. This offers you maximum flexibility and optimal use of your PV energy.

Operating Modes in Various Combinations

...with WiFi Meter
When used with the my-PV WiFi Meter, the AC-THOR 9s utilizes excess energy from your PV system to continuously power up to three electric heaters. Whether you have heating elements, electric heating mats, or infrared panels—your home benefits from optimal energy utilization.

...with battery storage
When combined with compatible battery storage systems, it—like the AC-THOR—performs a practical hybrid storage function. It stores excess PV energy not only in hot water but also in the building’s thermal mass. This ensures that excess PV output is optimally utilized, even with larger systems. The priority between battery and thermal storage is perfectly regulated.

...with Smart Home
The Power Manager is flexible in its application and, thanks to its open-system control, also communicates with various energy management systems. In addition to the my-PV WiFi Meter, it can thus also receive surplus energy data from other sources. This enables seamless integration into custom home automation systems. The data can be visualized in the Smart Home system.
