What this product is
What this product is
The S4875G1 is a high-frequency isolated DC-DC step-down solar MPPT converter controlled by advanced digital signal processors (DSP), packaged in a modular 1U hot-pluggable enclosure equipped with integrated CAN communication bus and variable-speed dual-ball cooling fans.
What problem it solves
Eliminates high fuel consumption and maintenance costs associated with off-grid diesel generators, mitigates erratic power fluctuation caused by cloudy conditions via ultra-fast MPPT, and bridges the gap between solar arrays and telecom DC power racks via unified hybrid slot operation.
Who and where it is for
Green telecom 5G base stations, remote microwave repeater sites, solar-diesel-battery hybrid off-grid power systems, and edge industrial IoT 48V DC cabinets.
Core advantages
- Ultra-High Peak Efficiency: Achieves ≥98.5% peak MPPT conversion efficiency, maximizing energy yield per square meter of solar panel arrays.
- Hybrid Parallel Operation: Can be mixed with Huawei grid rectifiers (like R4875G1) in identical subracks under unified SMU controller orchestration.
- High Density 1U Form Factor: Compact 1U hot-swappable modular architecture allows seamless live insertion without interrupting power supply.
- Harsh Environment Resilience: Designed to operate flawlessly between -40°C and +75°C, equipped with robust built-in surge protection.
