Take negative electricity rate into account

Information: This function is only available for PV systems in Germany and when a fixed feed-in tariff is configured.

The EEG (Renewable Energy Sources Act) feed-in tariff ceases to apply as soon as the electricity market price turns negative - effective from the first 15 minutes with a negative electricity rate. Such phases typically occur when a particularly large amount of solar power is fed into the utility grid - while demand is simultaneously low.
This rule applies to all new PV systems between 2 and 100 kW that go into operation on or after February 25, 2025, regardless of whether a control device is present, provided the system is not participating in direct selling.

When the electricity prices are negative, the feed-in tariff is set to 0 €/kWh. Activating this function has no impact on energy management or load planning, but it serves to calculate compensation more accurately.
