Product Overview
The CE+T Bravo ECI T521D70201 modular inverter is professional high-efficiency power conversion module designed by CE+T Power, adopting exclusive ECI redundant architecture to eliminate single-point failure risk. Rated at 3kVA/2.5kW, it converts nominal 336VDC battery power into stable 230VAC pure sine wave output, equipped with extra auxiliary AC input to boost running efficiency drastically. Multiple modules can be freely paralleled to build single-phase or 3×400V+N three-phase power system, scalable from standalone 3kVA up to maximum 1.35MVA large uninterrupted power station. Widely applied in high-voltage battery energy storage, industrial control, data room and telecom base station AC backup power scenarios.
Key Features
Standard 2U 19-inch rack mounting dimension, compact structure for embedded cabinet installation
Dual-source input design: nominal 336VDC(200~400VDC wide range) + 230VAC auxiliary input, AC→AC efficiency up to 96%, DC→AC up to 94.5%
Zero-transfer automatic switchover between mains AC and battery DC when grid blackout, uninterrupted critical load power supply
Pure sine wave output with ultra-low ripple, no interference to battery bank and sensitive DC loads
Hot-swappable module structure, single unit replacement without shutting down whole power system, reduce maintenance downtime
Flexible system configuration: ≥3 modules form complete three-phase 400Vac+N infrastructure, max expand to 1.35MVA system capacity
Built-in overload protection: 15s 150% short-time overload, 110% continuous overload resistance under rated ambient
Intelligent temperature-controlled fan cooling, wide working range -20℃~+65℃ (power derating over 40℃)
CE & RoHS certified, fully comply with international industrial and telecom power safety specifications
