Paragraph 14a EnWG: Defending Your Energy Autonomy in 2026
Under §14a EnWG, German grid operators now have the right to "throttle" (dimmen) heat pumps and EV chargers to 4.2 kW during peak grid stress. Homeowners are realizing that "electrification" can mean "less comfort"—unless they have a buffer.
The Strategy: The Battery as a Shield
A battery is no longer just for the night; it is a buffer for the day.
Growatt: The WIT-series for Gewerbe (SMEs) is essential. It ensures business machinery stays at 100% power using stored energy, even if the grid operator restricts the main connection.
Huawei: The Luna S1 detects the grid's throttle signal and immediately begins discharging to cover the shortfall. The user never notices a drop in comfort or charging speed.
Conclusion: Stay in Control of Your Home
The German energy transition requires a "buffer for freedom." By selling batteries as a defense against §14a throttling, you ensure your customers stay warm and their cars stay charged, regardless of what the grid operator decides.
FAQ: Germany - §14a EnWG
Can the grid operator turn off my heat pump? No, they can only throttle it to a minimum of 4.2 kW.
Is §14a mandatory? Yes, for all new controllable loads above 4.2 kW installed after Jan 1, 2024.
Does a battery stop the throttling? It doesn't stop the signal, but it provides the power the grid is denying you, so you don't feel the effect.
Is a Smart Meter Gateway mandatory? Yes, for all new §14a-compliant installs to facilitate remote management.
