This page documents Enode’s Solar Curtailment Early Adopter program.

Contact your Customer Success Manager to join the program and help us pilot and shape this feature.

</aside>

Solar curtailment lets you reduce or stop an inverter's grid export or generation through the Enode API. Use it to limit solar output during periods of oversupply or negative pricing.

This guide walks you through setting up curtailment: understanding the two limit types, sending commands, monitoring actions, and reverting safely.

Prerequisites: You need a linked Inverter and HEM System from the supported brands with the new control scope inverter:control:power_limit.

Changelog

Getting started

1. Join the Early Adopter program - reach out to your Customer Success Manager to be included in the program
2. Set up and link and inverter - curtailment builds on the HEM system foundation. Link an inverter, the HEM System gets created automatically
   1. Include the control scope - add inverter:control:power_limit to your Link UI configuration
3. Check capabilities - verify which limit types are available for a system
4. Run your first curtailment event - use the API to dim solar generation

During the Early Adopter phase, you have direct access to Enode's Home Energy team. For any questions or feedback, please reach out directly via slack/teams.

Why curtailment?

Curtailment reduces costs created by exporting solar during negative price periods.

• Market context: who pays for unnecessary solar exports

Power limits

Enode's curtailment API gives you direct access to two power limits on the inverter. Both are set through a single endpoint using a limitType discriminator:

• Export limit: limits the maximum power exported to the grid (requires an inverter bundled meter) without impacting self-consumption
• Generation limit: limits the maximum power output from the inverter into the household
