Grid-supportive feed-in control for specialist partners

Classification

Peak shaving reduces grid peaks

Specialist partners are the link between end customers, system planning and grid connection.

Grid-serving feed-in control limits peak output from PV systems. New systems should be planned so that they feed no more than 70% of their installed module capacity into the public grid. For customers, the majority of annual production remains usable; this mainly affects a few production peaks on very sunny days.

Implementation variants

Choose the right control system for the installation and the customer’s situation

Depending on the system, self-consumption, storage and control, different technical implementations are possible.

Simple limitation

These variants are suitable if the feed-in limitation is to be implemented directly and robustly.

Procedure

How to integrate feed-in control into your project

The regulation should already be taken into account in the dimensioning, quotation and technical submission.

Specialist partners create clarity by informing customers early, choosing the appropriate implementation option and documenting the technical details carefully.

01

Assess system and connection

Check the module output, inverter output, connection capacity, load profile and planned self-consumption.

02

Select implementation option

Specify whether a fixed limitation, a control system, a storage system or an energy management system is used.

03

Advise customers

Explain the benefits, technical implementation, potential yield losses and optimisation options transparently.

04

Submit and document

Submit the technical specifications in full and document the parameterisation, control and evidence for commissioning.

Technical planning

Understand the 70% limit as a planning parameter

The regulation does not replace the careful design of the system, connection and self-consumption.

The feed-in limit reduces the maximum power that is fed into the public grid. The energy produced can still be consumed locally, stored, or used optimally via an energy management system. Especially for systems with high daytime consumption, charging infrastructure, storage or process loads, curtailment can be significantly reduced.
