Short Explanation

In a small holiday village with ten houses, the AC•THOR uses energy from the in-house 9.3 kWp photovoltaic systems for hot water preparation. Each building provides two residential units with clean, free hot water. The buildings are arranged in a rectangle, ensuring the PV modules are either south or east/west oriented. PV performance measurement in all houses is carried out by the my-PV Power Meter.

The ten AC•THOR units regulate 3 kW heating rods in ROTEX hot water storage tanks steplessly. When sufficient power is available, a second 3 kW heating rod is added. This allows a regulation range of 0 – 6 kW for each hot water storage tank. The maximum target temperature for PV electricity is set to 65°C. At the same time, the proven hot water assurance from my-PV ensures no loss of comfort, even on days with insufficient solar radiation.

With the AC•THOR 9s, a regulation range of up to 9 kW would even be possible!
