Optimum use of excess solar energy with a combination of my-PV control units and RCT Power solar storage systems

The owners of PV systems can now use the solar energy they generate more efficiently: my-PV control units and RCT Power solar storage systems communicate with each other. The energy which cannot be stored by the fully charged battery is simply diverted to the hot water storage tank.

If the PV system generates excess electrical power of 1 kW, the energy created by this excess power is directed into the domestic hot water storage tank. If it generates excess electrical power of 2 kW, the energy created by this excess power is redirected to the domestic hot water storage tank. Up to 3 kW of excess electrical power generated, no excess energy is fed into the grid.

The PV system owner can increase his self-consumption of the generated solar energy when using my-PV control units and RCT Power solar storage systems in combination and thus become even more independent from the energy providers. In addition, the heating system does not need to be run conventionally during the summer period increasing the economics of the battery storage system installation. A specific example: A typical four-person household requires approximately 1300kWh for domestic hot water preparation in the spring to autumn period. If this energy demand is covered by excess energy produced by a PV system with 6 kWp it translates into a 20 per cent increase in self-consumption.  The interaction between my-PV control units and the RCT Power solar storage systems allows the PV system’s excess solar energy to be used more efficiently. 

RCT Power and my-PV have ideally matched their products to work with each other. This presents a further contribution to the tying of the power generation sector to the energy consumption sectors and the sustainable use of solar energy.
