Enterprise Fleet Telemetry

Real-time synchronization with enterprise solar SCADA.

Bridge on-site field diagnostic logs directly into your central operations platform. PVDIAG continuously syncs curve sweeps, string health registers, and thermal indicators without manual data exports or spreadsheet overhead.

Bidirectional SCADA Sync

Publish high-resolution IV curves and fault alarms directly to Ignition, OSIsoft PI, or custom Modbus networks in under 120ms.

Edge Storage & Offline Cache

Field technicians retain full diagnostic capability without cellular coverage; telemetry automatically buffers and syncs upon reconnection.

CMMS Work-Order Automation

Correlate string anomalies with asset serials to automatically generate maintenance tickets in SAP PM, Maximo, or Procore.
