Frequently Asked Questions About Covolt Horizon

Covolt Horizon is the technological ecosystem that Covolt uses to monitor, control, and provide insights into your renewable energy installation. It consists of three components: the Horizon Dashboard (our internal EMS), the Horizon Control Box (the control unit at your site), and the myHorizon app (your customer portal).
Covolt Horizon is designed for large business customers with one or more renewable energy installations—such as solar panels, battery systems, or charging stations. Whether you’re a farmer, a property manager, or an industrial customer, Horizon adapts to your specific needs.

The Horizon Control Box is our on-site control unit. The Control Box communicates with your hardware—inverters, batteries, power meters, and charging stations—and executes control instructions from our platform in real time.
The myHorizon app is your personal customer portal. You can view real-time energy flows, returns by strategy, battery status, and Covolt’s control settings—all clearly displayed on your mobile device.
Yes. Our systems support the Belgian market, including specific communication protocols for Belgian network operators.
