- • 15-20 year degradation & augmentation modeling
- • LCOS (Levelized Cost of Storage) analysis
Tender Engineering & RFP Documentation
Drafting comprehensive Employer's Requirements, technical specifications, and performance guarantee schedules for competitive EPC bidding.
- • EPC contract risk matrix & SLA terms
- • Vendor technical evaluation & scoring
- • Warranty & capacity retention agreements
Factory Acceptance Testing (FAT) Witnessing
Physical inspection and witness testing at cell, rack, and container fabrication facilities to enforce manufacturing quality standards before dispatch.
- • Cell grading, internal resistance & capacity test
- • Thermal propagation & BMS safety tests
- • Inverter PCS full-power factory testing
EPC Contractor Oversight & Site QA/QC
Full-time engineering supervision on-site managing civil foundations, electrical installations, cabling, earthing, and safety adherence.

Complete BESS Turnkey EPC Infrastructure
From containerized battery racks to high-voltage grid synchronization, Ultrathon Electric handles complete engineering, procurement, construction, and commissioning.
Containerized Battery Enclosures
ISO standard 20ft and 40ft high-cube insulated enclosures rated IP55/NEMA 4X. Equipped with advanced liquid cooling or high-efficiency HVAC loops to maintain uniform cell temperature (±2°C) for maximized life cycles.
Power Conversion Systems (PCS)
Bi-directional central and string PCS units delivering 4-quadrant active and reactive power control. Supports both Grid-Following (GFL) and advanced Grid-Forming (GFM) virtual synchronous generator algorithms.
NFPA 855 Fire & Deflagration Safety
Comprehensive multi-hazard life safety infrastructure designed to eliminate thermal runaway propagation risks in accordance with UL 9540A and NFPA 855.
MV Power Transformer & Switchgear
Outdoor Skid or kiosk-mounted step-up transformers stepping low-voltage PCS output up to 33kV, coupled with gas or vacuum circuit breakers for safe utility interconnect.
BESS Engineering Standards Matrix
Governed by IEC 62933 (BESS System), UL 1973 (Battery Safety), UL 9540A (Fire Testing), IEEE 1547 / 2800 (Grid), and CEA Connectivity Regulations.
