Bucium

The photovoltaic system installed on the roof of a house in the Bucium area (Iași) covers the energy demand during the day, with the delivered power automatically adapting to what the consumers need. The installed power is 5 kW, with an on-grid connection.

The SMA Home Manager coordinates the energy transfer between the producer (photovoltaic panels + inverter) and the consumers. It supplies the energy required and reduces the inverter's output when consumption is lower.

The Home Manager has been configured not to feed energy into the grid. When future regulations become favourable for producers of renewable energy, the settings can be changed so that surplus energy that is produced but not consumed is fed into the grid.

The owner can optimise consumption to make the most of the energy produced during the day (washing machines, sprinklers, electric oven, etc. are scheduled to run during the day), with the system monitored and controlled remotely through a mobile app.
