BESS Product Manager (Utility and Industry)

Position Summary

The Utility & Industrial BESS Product Manager owns the product vision, roadmap, and lifecycle for large-scale Battery Energy Storage Systems (50 kWh – 10 + MWh). The role spans market analysis, technical definition, product development, containerized system architecture, PCS/EMS integration, safety compliance, and commercial success.

You will work closely with engineering, supply chain, certification bodies, EPC partners, utilities, and large industrial customers to ensure successful deployment of grid-scale and C&I energy storage products.

Key Responsibilities

• Define product strategy for utility-scale and industrial BESS (AC-coupled, DC-coupled, hybrid ESS).
• Build the long-term roadmap for containerized BESS (250 kWh – 10+ MWh) and PCS/inverter platforms.
• Analyse global and domestic market trends (LFP cell tech, 2P/3P configuration, liquid cooling, fire safety).
• Define competitive differentiation in cost, safety, energy density, lifecycle, and digital integration.
• Conduct market sizing, TAM/SAM analysis, and customer segmentation (utilities, IPPs, C&I).
• Create PRDs and system specifications for:
• Battery packs, racks, and container architecture
• PCS/inverter requirements (20 ft/40 ft)
• HVAC/thermal management
• Fire Detection & Suppression (FDS)
• BMS/EMS integration
• Protection schemes, grounding, and grid code compliance
• Define performance KPIs: round-trip efficiency, degradation, availability, OPEX.
• Work with R&D on cell selection, topology choices, control algorithms, safety design.
• Coordinate with electrical, mechanical, thermal, firmware, and EMS teams.
• Drive certification requirements (UL9540, UL1741, IEC 62933, UL1973, IEEE 1547, BIS and other relevant standards as applicable).
• Support supply chain in selecting cells, racks, PCS, thermal systems, and auxiliaries.
• Enable manufacturability, configuration standardization, and cost optimization.
• Lead product introduction, field trials, and pilot deployments.
• Develop technical datasheets, manuals, and product documentation.
• Train internal teams (sales, service, EPC partners).
• Track product field performance using data analytics and customer feedback.
• Drive cost-down initiatives (cell sourcing, cooling redesign, cabinet/container optimization).
• Manage component EOL and product upgrades.
• Lead next-gen design initiatives (liquid cooling upgrades, modular PCS, sodium-ion readiness, etc.).
• Good Customer connect in utilities, IPPs, C&I, microgrid segments.
• Work closely with developer, consultant, EPC, and support design proposal, Product evaluation and technical clarification.

Preferred Experience

• Experience with containerized ESS (1 MWh – 5 MWh blocks).
• Knowledge of LFP, NMC, and emerging chemistries (sodium-ion, semi-solid).
• Exposure to battery Energy Storage Application: peak shaving, arbitrage, frequency regulation, black start.
• Hands-on with commissioning or lab testing of PCS/BESS systems.
• Experience in tender preparation, technical proposal, System Level Preliminary Design

Education Qualification

• BE/ME in Electrical/Electronics, Power Electronics.
• 5-15 Years of Experience in relevant industry
