Lead Field Service Technician - PV/BESS

Location: Multiple Sites / Regional Travel Required Job Type: Full-Time Level: Senior / Lead / Field Authority Job Summary We are hiring a Lead PV / BESS Master Technician with proven field authority, advanced troubleshooting capability, and the ability to lead commissioning and service execution on complex renewable energy systems. This position is built for a high-level field professional who can own technical performance from installation turnover through energization, commissioning, troubleshooting, remediation, and long-term operational reliability. This is not an entry-level role. This is not a helper position. This is not a role for candidates who require step-by-step instruction. We are looking for the technician who gets called when systems will not commission, performance is off target, communication networks fail, punch lists stall, or energization is at risk. Primary Responsibilities Serve as the technical field lead for solar PV and BESS commissioning, service, troubleshooting, corrective maintenance, and remediation Lead field crews, direct technical workflow, and enforce workmanship standards Execute cold commissioning, hot commissioning, functional testing, startup, energization, and performance verification Troubleshoot live DC and AC electrical systems under field conditions Diagnose and resolve inverter faults, production losses, communication failures, protection issues, and control integration problems Validate installation quality against drawings, single-line diagrams, OEM documentation, and commissioning procedures Interface directly with owners, utilities, AHJs, EPCs, OEMs, engineers, and commissioning authorities Produce detailed turnover packages, commissioning reports, punch lists, corrective action reports, and deficiency documentation Support project closeout, warranty investigations, recommissioning, and operational performance optimization Advanced knowledge of commercial and utility-scale PV systems Full understanding of: MLPE systems DC collection systems AC collection systems transformer and switchgear integration protection and interconnection architecture Advanced Electrical Troubleshooting Must be capable of independently diagnosing: Ground faults Arc faults Insulation resistance failures Voltage imbalance clipping and curtailment issues failed terminations polarity errors intermittent production faults Must have hands-on field experience with: Digital multimeters Clamp meters IV curve tracers Insulation resistance testers (Megger) Thermal imaging cameras continuity and polarity testing equipment Must be able to interpret test data , not simply perform the tests. Hands-on commissioning, startup, troubleshooting, and service experience with: Required abilities: firmware upgrades parameter configuration protection verification grid support function setup inverter replacement and recommissioning Monitoring / SCADA / Communications Hands-on experience configuring and troubleshooting: Ethernet networks fiber communications

Competitive compensation based on experience Leadership-level field responsibility Exposure to complex commercial, utility-scale, and storage systems Opportunity to work on high-value commissioning, startup, and O&M projects The current U.S. solar market is facing a skilled labor shortage, especially for senior field and commissioning roles, which is pushing greater value toward technicians who can independently lead energization and turnover. #J-18808-Ljbffr Pps
