TS-4850H Series High Voltage Solar Charge Controller Module

Description

TS-4850H is a 1U rack-mounted high-voltage MPPT solar charging module specifically designed for CONSNANT communication. It is developed for 48V communication base stations, edge rooms, integrated power cabinets, and photovoltaic energy storage communication systems. It belongs to the category of high-power DC-DC photovoltaic charging units, with the low-voltage version of the same series being TS-4850L.

Key Features：
1. Wide High-Voltage PV Input for Large PV Arrays
• Supports 120–425Vdc PV input, allows more solar panels connected in series to form high-voltage strings, effectively reducing cable loss and wiring cost.
• Stable MPPT tracking range: 120–340Vdc, startup voltage ≥160V, maintains stable power capture under weak light conditions.
• Maximum withstand input voltage up to 430V, with input overvoltage latch protection to shut down the module automatically under PV surge conditions.
2. High-Precision MPPT with Ultra-High Conversion Efficiency
• MPPT tracking accuracy ≥99%, maximum overall conversion efficiency reaches 98%.
• Real-time dynamic tracking of the maximum power point, generating over 30% more electricity than traditional PWM solar controllers.
• Adopts digital dual closed-loop voltage & current control, delivering stable power output without power oscillation.
3. 3-Stage Intelligent Charging for Multiple Battery Types
• Standard three-stage charging logic: constant current bulk charge → constant voltage absorption charge → float charge, with equalization function to desulfate lead-acid batteries and extend service life.
• Customizable charging voltage curves, compatible with flooded lead-acid, sealed gel and 48V lithium iron phosphate batteries.
• Built-in temperature compensation function, automatically adjusts charging voltage under high/low ambient temperature to avoid overcharging or undercharging.
• Output voltage accuracy ≤±0.2V to fully protect storage batteries.
4. 1U Hot-Swappable Modular Design for Easy Expansion & Maintenance
• Standard 1U plug-in size, mechanically compatible with telecom high-frequency rectifier modules for mixed installation in one cabinet.
• Multiple TS-4850H modules support parallel current sharing to increase total system charging capacity on demand.
• Front lock buckle and quick plug terminals, single module can be replaced without shutting down the whole cabinet.
• Integrated air duct and intelligent temperature-controlled fan: low-speed silent operation at low temperature, full-speed heat dissipation at high temperature.
5. Comprehensive Multi-Level Electrical Safety Protection
• PV side protection: input overvoltage, undervoltage, reverse connection, short circuit and anti-reverse current.
• Battery side protection: output overvoltage, undervoltage alarm, overcurrent, short circuit and reverse connection.
• Whole machine protection: over-temperature power derating / shutdown, module current limiting, anti-circulation, lightning surge protection compliant with IEC61000-4-5.
• Hierarchical fault response: minor faults auto-recover; severe overvoltage triggers latch protection, reset by power cycle.
6. Isolated Standard Communication for Remote O&M
• Built-in isolated RS485 bus with standard Modbus protocol, compatible with mainstream telecom power monitoring units.
• Real-time upload of PV voltage, charging current, battery voltage, module temperature and fault alarm data.
• Supports remote parameter modification, module start/stop and fault record storage, perfectly matching room environment monitoring systems.
• Front panel LED indicators clearly display running, charging and fault status for fast on-site troubleshooting.
7. Industrial-Grade Reliability & Global Certifications
• Wide operating temperature range: -20℃ ~ +55℃, reliable operation in harsh outdoor base station environments.
• Reinforced dust-proof and anti-vibration structure, meets reliability standards for outdoor communication equipment.
• Certified with ISO, IEC and CE, satisfying bidding qualification requirements for domestic and overseas telecom projects.
• Ultra-low standby power consumption, almost no power drain from batteries when no PV input at night.
