Utility-Scale

Utility-Scale Solar
Technical Support & Diagnostics

Utility-scale solar plants operate under tight performance agreements and strict grid compliance requirements. When a central inverter trips, SCADA goes offline, or a protection relay activates unexpectedly, the financial stakes are high. Our specialists provide remote diagnostic support to help you assess, document, and resolve issues efficiently.

Capabilities

Utility-Scale Support Services

Central Inverter Diagnostics

Remote fault analysis for large central inverters from Advanced Energy, Sungrow, SMA Sunny Central, ABB/FIMER, Yaskawa Solectria, and others. We help interpret complex fault logs before dispatching a service crew.

SCADA & Monitoring Support

Troubleshooting Modbus, DNP3, IEC 61850, and Ethernet communication issues between inverters, weather stations, meters, and the plant-level SCADA system.

Grid Compliance & Interconnection

Review of inverter settings against utility interconnection requirements — voltage ride-through (LVRT/HVRT), frequency response, reactive power, and power factor settings.

Commissioning Support

Remote guidance during utility-scale plant commissioning — inverter startup sequences, grid code verification, protection relay coordination, and pre-energization checklists.

Performance Analysis

Review of SCADA data, clipping losses, PR degradation trends, and inverter-level production discrepancies to identify underperforming blocks before they affect PPA obligations.

Emergency Response

When a plant trips offline or production drops unexpectedly, our specialists are available to help assess cause and coordinate with on-site personnel on a safe, documented restart path.

Before You Call

What to Prepare Before Your Session

Having this information ready helps us assess your issue efficiently and make the most of the support session.

Plant Details

Plant name, total capacity (MW), number of inverters, and inverter manufacturer and model.

Fault Description

What happened, when it started, and the production or revenue impact.

SCADA or DAS Data

Exports or screenshots from the plant monitoring system showing the fault event and surrounding period.

Fault Logs & Alarms

Inverter fault logs, alarm history, and any protection relay events.

Weather Data

Irradiance and temperature data for the period in question, if available from the on-site weather station.

Interconnection Requirements

The utility-approved inverter settings profile or interconnection agreement, if the issue is grid-compliance related.
