What is the TommaTech Heatpump Controller Box?
TommaTech Heatpump Controller Box is a control box that integrates a heat pump with a TommaTech inverter and energy storage system. It aims to manage the use of surplus solar energy in the heat pump through the inverter settings.
According to the manufacturer, when PV production exceeds the home's needs during the day and the batteries are completely full, the surplus can be used to feed the heat pump; this way the heat pump runs on a higher share of solar energy and the energy bill can be reduced. No additional technical values are given in the product information.
Which projects is it suited for?
In systems that combine a heat pump with solar energy, the following scenarios stand out:
- Homes with heat pumps that run on solar panels, a hybrid inverter and batteries
- Villas with high heating and hot water demand
- Users who want surplus production used in the home instead of being fed into the grid
Installation considerations
The heat pump, inverter and control box must be selected to be compatible with each other; before installation, it is checked whether the heat pump has an external control input and whether the inverter software supports this function. The threshold at which surplus energy is directed to the heat pump is set in the inverter settings; since a wrong setting can cause the heat pump to cycle on and off unnecessarily, commissioning by an expert team is recommended.
Use in Antalya and Solar Nexo support
Winters in Antalya are mild and heating demand is lower than in northern regions, but a heat pump can run all year round for hot water, pool heating and air conditioning. Directing surplus energy to the heat pump during the hours of high solar production increases the share of self-consumed energy.
Solar Nexo verifies the compatibility of the heat pump, inverter and control box at the project stage, and carries out installation and commissioning. You can consult our technical team for compatible heat pump models.
