The Terli DC OEM Emergency Power System for Building carries a complete global market battery certification stack. OEM brand owners avoid independent testing costs — eight certifications ship with every unit.
CE: Clears EU market distribution covering EMC and low-voltage safety directives
TUV: Delivers independent safety verification for European and international procurement programs
KC: Clears South Korean market entry without additional testing
UN38.3: Satisfies lithium battery transport requirements demanded by freight forwarders and customs globally
MSDS: Provides required documentation for international shipping and storage compliance
CB scheme: IEC-based OEM battery certification cutting per-market re-testing costs across 50+ countries
ISO: Third-party-audited manufacturing quality management system
3C (CCC): Covers China Compulsory Certification for domestic market distribution
Terli supports full OEM/ODM development for the DC emergency power system for building — covering enclosure design, brand labeling, and firmware customization. Brand owners receive a private label emergency power product built to their specification, not a repackaged stock item.
Production runs through 7 defined steps. These span from Outer Box Preparation and Cell Preparation through Product Assembly, Product Testing, and Product Packing to final shipment. Terli manufactures core components in-house, placing quality control at the cell level rather than at final inspection only.
The platform covers three form factors: Pack X (19-inch 5U), Energy Storage System (19-inch 5U), and Telecom Battery (19-inch 6U). This range gives OEM partners a custom rack battery system base across building, telecom, and commercial markets. ISO-certified production backs batch consistency across repeated orders.
The DC emergency power system for building uses LiFePO4 chemistry with a stable electrochemical structure. This chemistry eliminates thermal runaway — passing extreme safety tests without fire or explosion risk.
Independent BMS per module: Each module runs its own LiFePO4 battery BMS protection system, covering overcharge, over-discharge, short circuit, over-current, and thermal cutoff. A fault in one module does not affect others in the stack.
Modular scalable design: The modular battery system ships in a compact, lightweight enclosure. Capacity expands by stacking additional units without rewiring existing installations.
Pulling-ear quick installation: The standard 19-inch rack form factor fits existing rack infrastructure. The pulling-ear mechanism locks units into position without additional tooling.
Wide operating temperature: The system operates from -10°C to 50°C, covering building mechanical rooms, outdoor enclosures, and telecom cabinet environments.
Multi-protocol communication: RS485, CAN, and RS232 interfaces connect directly to mainstream inverters, MPPT controllers, and monitoring platforms.
LCD display: The on-unit screen shows SOC, voltage, current, and cell-level data without external software.
At 6,000+ cycles versus lead-acid’s 300–500, this DC emergency power system for building cuts OEM battery total cost of ownership by eliminating mid-contract replacements. The 10-year design life aligns with commercial building system lifecycles — reducing warranty claim exposure for brand owners.
LiFePO4 eliminates thermal runaway risk — the primary fire hazard from NMC chemistries in enclosed building environments subject to fire codes. Per-module BMS fault isolation means a single failed unit does not interrupt the remaining stack.
The -10°C to 50°C operating range removes the need for heating or cooling enclosures across most global deployment environments. Pre-certified CE, TUV, KC, and UN38.3 coverage supports building emergency power reliability in multiple markets from a single supplier — OEM partners avoid partial-cert gaps across regions.
The DC emergency power system for building serves four primary market segments. Each deploys through the standard 19-inch rack form factor and multi-protocol communication support.
Commercial building emergency power. The system provides DC continuity for building backup power applications: elevators, emergency lighting, fire alarm control panels, and building management systems.
Telecom infrastructure. The telecom battery backup system application uses the 19-inch 5U/6U rack format for direct cabinet integration at base stations and communication sites.
Data center and industrial UPS. Server rooms, control rooms, and industrial automation facilities use the system as an uninterruptible power source in standard rack installations.
Solar and renewable energy. RS485/CAN compatibility connects the system to MPPT controllers and hybrid inverters, making it a solar energy storage system for off-grid and grid-tied projects.
The -10°C to 50°C operating range opens deployments across Middle East, Southeast Asia, and cold-climate regions without auxiliary thermal management.
