How it works

Three layers. Zero manual intervention.

  1. 01 · Field

    Your inverters & meters

    Read over Modbus TCP/RTU or SunSpec. Any mix of brands, up to 200 devices per site.

  2. 02 · Edge controller

    GES Plant Controller

    Industrial DIN-rail unit with closed-loop power control at the point of connection. Keeps running offline.

  3. 03 · Grid

    CEBAssist

    Secure, encrypted link for setpoints, status and telemetry. Commands executed in under 2 seconds.

Everything a grid-connected plant needs to stay compliant.

01

Remote dispatch

Active power setpoints from CEBAssist applied plant-wide in under 2 seconds.

02

Export limiting

Zero-export or fixed-limit control at the point of connection with a revenue-grade meter.

03

Reactive power & PF

Q(U), fixed PF and voltage support modes to meet connection requirements.

04

Real-time telemetry

Power, energy, voltage and alarm data streamed every few seconds.

05

Offline resilience

Last setpoint held and data buffered locally if the link drops.

06

Audit-ready logs

Every command and response time-stamped for compliance reporting.

What plant owners say

“CEB sends a setpoint, the plant follows within seconds. We stopped worrying about compliance and started looking at yield again.”

Frequently asked questions

What is CEBAssist and why do I need to connect to it?+

CEBAssist is used to coordinate grid-connected solar plants. Connecting lets the grid operator see your plant and issue control commands, which is increasingly required for new and existing installations.

Do I need to replace my inverters?+

No. Our controller talks to your existing inverters over standard protocols. Mixed-brand plants are supported.

How long does installation take?+

Rooftop and commercial plants are typically commissioned within 3–5 working days of site survey.

What happens if the internet goes down?+

The controller keeps enforcing the last valid setpoint and export limit, buffers data locally and syncs once the link is restored.

Is the hardware included in the price?+

Yes. Controller hardware, configuration and remote support are included on every plan.
