Job description

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.

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
• RS‑485
• Modbus TCP
• Modbus RTU
• remote monitoring platforms
• inverter telemetry validation
• communications fault isolation

Battery Energy Storage Systems (BESS)

Required Working Knowledge

Candidates with strong BESS field experience are strongly preferred.

• AC‑coupled and DC‑coupled architecture
• PCS (Power Conversion System)
• BMS (Battery Management System)
• SCADA integration
• battery racks and containerized systems
• control and protection interfaces
• functional startup logic
• fault isolation and safe shutdown procedures
• pre‑functional inspection
• startup readiness verification
• battery communications verification
• sequence‑of‑operations testing
• functional control testing
• operational verification
• capacity validation support
• troubleshooting communication and controls faults

Growing utility‑scale storage deployment is increasing demand for technicians who can support field energization, controls integration, commissioning documentation, and safe turnover.

Safety & Compliance

Must demonstrate working knowledge of:

• OSHA
• NFPA 70E
• Lockout / Tagout
• arc‑flash practices
• job hazard analysis
• energized work planning
• NEC Article 690
• NEC Article 705
• NEC Article 706

Basic familiarity with NFPA 855 and UL 9540/9540A preferred for storage systems.

The Lead PV / BESS Master Technician is expected to:

• lead crews in the field
• identify issues before they become delays
• communicate clearly with field management and clients
• make sound technical decisions without escalation
• protect schedule, quality, and system performance

Required Experience

5+ years of hands‑on commercial or utility‑scale PV field experience

• Proven lead technician, commissioning technician, or senior service technician experience
• Demonstrated success diagnosing live system failures
• Ability to work independently under field pressure
• Ability to travel to project sites

Preferred Qualifications

• OSHA 10 / 30
• NFPA 70E
• SMA
• Enphase
• Tesla
• Fluence
• Powin
• Sungrow storage platforms

What This Role Is Not

• Not a remote position
• Not a training seat
• If you need daily instruction to perform technical work, this role is not a fit.
• 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.

How to Apply

• years of hands‑on PV experience
• system sizes worked on
• commissioning experience
• inverter platforms supported
• BESS experience
• examples of major troubleshooting work personally completed

Only candidates with proven field capability will be considered.
