String-Level Work:

Diagnose and repair faults within PV module strings on site.

Proficient use of string testers to identify issues, interpret results, and communicate findings effectively to supervisory staff.

Navigate monitoring portals to locate underperforming strings and perform physical repairs including fault tracing and panel replacement.

Replace string home runs when necessary and handle DC cable terminations using MC4 connectors.

Communications and Monitoring:

Conduct detailed diagnostics on communications hardware to determine fault causes and component health.

Understand the interplay between communications devices such as routers, data loggers, and monitoring systems.

Verify 3G SIM card functionality and remotely monitor inverters using online platforms.

Interpret inverter alarm data and yield deviations, taking into account environmental and array design variables.

Identify and diagnose inverter faults using error codes and system analytics.

Inverter Maintenance:

Work safely with various inverter brands (e.g., SMA, Huawei), performing tasks like firmware updates via multiple connectivity methods (Wi-Fi, Ethernet, RS485).

Download and interpret event logs from inverter interfaces.

Troubleshoot alerts from inverter managers and monitoring platforms (e.g., Weblog, Bluelog).

Log faults with manufacturers' support and follow up until resolution.
