Description
OD-TRSS series is an integrated outdoor hybrid energy telecom power system independently developed by CONSNANT, combining high-efficiency AC rectifier modules and multi-channel MPPT solar charge modules, delivering standard -48VDC power supply for telecom equipment.
Designed for mains + photovoltaic complementary power supply, the system realizes solar priority energy dispatch to maximize solar utilization and cut site electricity expenditure. It supports seamless coordination of mains grid, PV panels, storage batteries and optional diesel generator, ensuring zero-interruption power supply for remote communication sites with unstable power or no grid coverage. The whole machine adopts IP55 outdoor cabinet structure with compact layout, front access maintenance, and optional air conditioner/electric heater to adapt to extreme outdoor environments.
Working Principle：
Under normal grid power, rectifier modules, MPPT solar modules, load equipment and batteries operate in parallel floating charging mode. Solar power supplies loads and charges batteries preferentially; when solar output is insufficient, rectifiers automatically supplement power.
1. Mains outage with normal PV output: Solar modules feed loads and charge batteries.
2. Mains outage + PV failure: Batteries discharge to sustain loads. When battery voltage drops to generator startup threshold, the monitoring unit sends startup signal to diesel generator; the generator supplies AC to rectifiers to recharge batteries and restore full load power. When battery voltage reaches generator stop threshold, the system shuts down the generator automatically.
Core Features：
1. High-Performance Hot-Swap Power Modules
◦ MPPT solar tracking accuracy ≥99.5%, solar module efficiency ≥95%; rectifier with active PFC (PF≥0.99), peak efficiency ≥93%~96%.
◦ Non-destructive plug-and-play hot swap for rectifier & PV modules; module replacement finished within 1 minute without system shutdown.
◦ Dual hardware + software overvoltage protection; software OVP supports two lockout modes for selection.
◦ High power density, 1–6 modules for 300A model, 1–12 modules for 600A model for flexible capacity expansion.
2. Intelligent Battery Management System
Full battery protection suite, automatic voltage regulation, stepless current limiting, real-time battery capacity calculation, auto float/equal charge switching, online battery health test function.
3. Optimal Solar-Grid Complementary Control
Intelligent energy management logic prioritizes PV power output to loads, fully exploits renewable energy to reduce grid consumption and carbon emissions.
4. Complete Data Statistics & Historical Recording
Real-time statistics of load power consumption, PV generation, mains power input, diesel generator output, battery charge/discharge volume; stores 90-day historical operation data, 200 fault alarm records and 10 groups of battery test data, all data remotely uploadable.
5. Comprehensive Alarm & Multi-Layer Protection
Full-range electrical protection: AC over/undervoltage, PV over/undervoltage, output OVP/UVP, overcurrent, short-circuit, over-temperature, PV reverse polarity protection; built-in AC & DC two-stage lightning protection SPD for thunderstorm-prone regions.
6. Humanized Monitoring & Remote Management
15° inclined LCD operation panel for intuitive parameter query, historical alarm check and manual system control; supports dry contact alarm, RS485 communication, optional GPRS modem for cloud remote monitoring and unattended site operation; local software upgrade available.
7. Advanced Energy-Saving Design
Rectifier automatic sleep function under light load, dual steady-state contactors, low-power shunt and variable-speed fan technology to lower standby power loss.
