You primarily prepare your hot water using photovoltaics. If there is excess photovoltaic power, this energy is simply fed into a micro PV inverter. This allows you to use excess energy to reduce electricity costs.

Configure your own hot water supply with surplus feed-in. We recommend the following products:
- 1x photovoltaic heating element
- 4x photovoltaic modules
- 2x 10m extension cable (switching device to the boiler)
- 4x 5m extension cables (from the photovoltaic modules to the switching device)
- 1x fothermo switching device
- 1x Micro PV inverter

Configure your own hot water supply with surplus feed or use our pre-assembled set.
