Sr. Technical Analyst, BESS & Inverter

Location: San Francisco, CA, United States Location Type: On-site Salary Range: 105000 - 140.000 USD Annually

We are looking for a Sr. Technical Analyst, BESS & Inverter Technical to join the Team AVL Tech SMEs sub-pod within EnFin's Offering Development organization to serve as the deep-domain technical authority for all battery energy storage and inverter technologies on the EnFin Approved Vendor List (AVL). The ideal candidate will have experience in residential and light-commercial solar and storage equipment, with fluency across the major BESS and inverter vendor landscape (Tesla, Enphase, SolarEdge, Franklin, EG4, Sol-Ark, Fortress, Panasonic, LG, and others), and will work closely with the PV/Racking Tech SME, the AVL Integrations Engineer, the AVL Project Management sub-pod, Team IRA, Engineering, Quality, Procurement, Field Operations, and the Qcells in-house hardware organization.

This position will be based out of our San Francisco, CA office with an in-office schedule set at the direct manager's discretion in accordance with the company policies and procedures. Remote may be considered in exceptional cases. Travel up to 25%.

Responsibilities

• Own technical evaluation, OEM qualification, technical onboarding, and annual AVL technical refresh for residential and light-commercial hybrid inverters, string and microinverter platforms (including Qcells Q.MI), and BESS systems; lead technical scoring on RFPs and report quality, performance, and reliability trends at QBRs.
• Own the accuracy of BESS and inverter records in the Airtable AVL golden record — setpoints, datasheet parameters, loss factors, certifications — and audit third-party design tool libraries (Aurora, Solargraf, Solo, OpenSolar) for accurate product representation; partner with the AVL Integrations Engineer on schema mapping into Salesforce Master Equipment.
• Define authoritative technical parameters for each approved product (efficiency curves, MPPT settings, derate curves, round-trip efficiency, UL 9540 / 9540A, IEEE 1547-2018, Rule 21) and maintain MBOS / EBOS compatibility matrices for all approved combinations.
• Run pre-launch AVL readiness reviews on every Qcells in-house BESS, inverter, and Q.MI microinverter SKU and variant; coordinate readiness milestones with the Qcells hardware organization and provide structured field-performance feedback for next-generation product specifications.
• Attend pilot installations, support O&M escalations and RMAs, and conduct failure-mode analysis; deliver technical training to internal teams and external TPO partners on BESS and inverter technologies, compatibility rules, and troubleshooting.
• Author and maintain the AVL requirements documents for BESS and inverter products on the AVL Hub — defining the technical, certification, and compatibility bar (UL 9540 / 9540A, UL 1741-SB, IEEE 1547-2018, NEC, Rule 21, interconnection) that OEMs must clear for approval. Curate the virtual dataroom in Airtable that holds OEM-submitted compliance records, certification artifacts, and supporting documentation for products applying to and approved on the AVL; ensure records are complete, current, and auditable for AVL governance, AHJ inquiries, and FMV / capital markets reviews.
• Author tech memos, install guides, integration diagrams, and troubleshooting guides as source content for the AVL Hub knowledge base; partner with the AVL Project Management sub-pod on packaging and distribution.
• Provide product-domain technical input to Team IRA on DCA / FEOC / Safe Harbor / IRA §45Y / §48E matters (Team IRA owns the policy-compliance evidence); supply technical traceability artifacts to Strategy, Finance, and Capital Markets when FMV models are challenged or audited.
• Partner with the Product & Commercial Strategy Manager on joint decisions: AVL add/retire calls, vendor QBRs, buy-vs-partner decisions for Qcells in-house products, and setpoint accuracy through FMV.

Required Qualifications

• Bachelor's degree in electrical engineering or related technical field; or equivalent experience / licensing (e.g., journeyman or master electrician) with a minimum of 8+ years of professional experience including 5+ years directly relevant to this role and 2-3+ years in solar or storage.
• Demonstrated breadth and depth across the residential and small-commercial BESS and inverter vendor landscape — fluent in competitive positioning, failure modes, and differentiators of the major platforms.
• Hands-on working knowledge of at least two PV / storage modeling platforms (Aurora Solar, Solargraf, Solo, OpenSolar, PVsyst, SAM, HelioScope) including how their inverter and battery libraries are structured.
• Strong grasp of inverter and battery datasheet parameters, loss factors, and the modeling assumptions that drive production estimates.
• Working proficiency with Salesforce (custom objects, product catalog) and Airtable (bases, linked records, automations) — or demonstrated ability to become proficient quickly.
• In-depth knowledge of regulatory requirements: NEC, UL, IEEE 1547, Rule 21, UL 9540 / 9540A, interconnection processes.
• Strong written and verbal communication and professional presence; this role authors technical content that becomes EnFin's source of truth and represents EnFin to OEM partners and external stakeholders.
• Ability to work in a fast-paced, dynamic environment, manage competing priorities, and deliver results under tight timelines.
• Excellent organizational skills and attention to detail.

Preferred Qualifications

• NABCEP PV Installation Professional or PV Technical Sales certification.
• Hands-on BESS / inverter installation, commissioning, or troubleshooting experience.
• Working knowledge of PV module behavior and MBOS / EBOS compatibility for AVL decisions.
• Experience working on or alongside a Smart Quote / design-to-proposal tool, vendor PIM, or equipment master-data program.
• Familiarity with AI-assisted content review, RAG-based knowledge tooling, or MCP integrations.
• Interest in scalable clean energy solutions and solar business operations.
