There are possibilities:

  1. Use the the Elios4you on-board relay. The smart switching ON/OFF are directly programmed from the App, depending on the available surplus energy and on configurable threshold / delay. It will be also possible to manage the switching on of the boiler in case there is no immediate energetic availability, to always keep hot water in storage.
  2. With the Power Reducer accessory. With a power reducer the user can accurately manage the solar PV self-consumption. Therefore, combined with Elios4you, the Power Reducer can manage the energy consumed by the boiler depending on the surplus energy of the electricity users. In that way, even if the energy available is inferior to the consumption of the boiler’s resistance, it is possible to store domestic hot water (DHW) without drawing any energy from the grid.
