FAZOR collects telemetry from inverters, strings and batteries every second, finds losses and schedules charging by market price. For O&M engineers and CTOs running more than one plant.
The on-site gateway polls inverters, meters and BMS over Modbus and IEC 104, buffers data during link outages and backfills it without gaps.
Every string gets a model of expected current from irradiance and module temperature. A deviation above 6 % that lasts 20 minutes becomes a ticket with a map position and a likely cause.
The dispatcher plans the battery schedule a day ahead from market prices and the generation forecast, keeps headroom for grid limits and tracks cell degradation every cycle.
P10–P90 for 48 hours from numerical weather prediction and satellite cloud cover. Yesterday’s error is computed every morning and shown next to the forecast.
REST and an MQTT stream with the same IDs as the interface. Webhooks for tickets, history export to Parquet, keys scoped per plant.

We mount the gateway in the comms cabinet, map the registers and get first telemetry the same day.
We calibrate expected current on two weeks of data and switch on loss tickets.
First as an advisor, then an automatic schedule within the grid operator’s limits.
An on-call engineer, a monthly loss report and a review of every outage.
Send us the capacity and equipment list — within a week we connect one plant in read-only mode.
