- Tracker manufacturersYou build the mechanics but have no controller? Feldmelder provides box, tracker control unit (TCU) and portal for single-axis trackers – scope and how a pilot starts.
- EPCFor EPCs: open interfaces, a documented protocol, geometry as a file and a portal from commissioning – what Feldmelder delivers in projects.
- Owners and operatorsFor IPPs and owners: see whether every tracker follows the sun, alarms with escalation, data via API and CSV – and an independent controller.
- O&M providersFor O&M: alarms for angle deviation, outage, motor and drive-sync faults, escalation with maintenance windows and signed remote commands – Feldmelder in service.
- Agri-PVAgri-PV with trackers: safety positions, maintenance mode for field work, share links for farmers and honest limits – Feldmelder for agrivoltaic trackers.
Five roles, one system
Feldmelder consists of the box in the field (sun position, safety positions, buffer), a control unit per tracker (TCU) and the portal for monitoring, alarms and a few signed commands. The pages below describe what matters for your role – and what is built in the project.
How we work: every function of the box, the tracker control unit (TCU) and the portal is covered by automated tests. Field installations start with a pilot project and acceptance criteria agreed beforehand. The live demo shows an example plant with example data.
