Private consumption reaps its rewards

The incentives available for electricity generated by photovoltaic systems are currently being cut back in some countries. A PV system is nevertheless well worth the investment - particularly in light of the prospect of steadily increasing energy costs in the future.

In Germany, for example, numerous electricity suppliers are planning to increase their prices over coming months, even though electricity prices have increased by more than five percent a year on average in recent years.

Fronius demonstrates how one can take a relaxed attitude towards future increases in electricity prices: anyone who uses their own PV system to generate the electricity their home needs will benefit in the long run! The more solar power one consumes oneself, the less electricity one needs to buy at expensive rates from an energy supplier; this starts to pay dividends from private consumption levels as low as
15 %.

Optimise private consumption with Fronius inverters
With its Energy management relay, Fronius has developed a solution that enables privately generated solar power to be used right away. Fronius inverters allow a power range for private consumption to be specified. This means that on/off thresholds can be set on the inverter as units of power (Watts). If the inverter produces more than the set power (e.g. 2000 W), a relay output is activated and the solar power generated is used to operate a consumer, instead of feeding power into the public grid. The relay output is deactivated if the energy yield drops below a specified value (e.g. 1800 W).
