Product Overview
The Vertiv S48-3000 (Model 1S483000) belongs to eSure series professional MPPT solar DC-DC converter developed by former Emerson Vertiv, specially designed for NetSure series hybrid DC power cabinets in off-grid telecom sites. It converts 58~150VDC solar panel voltage into standard adjustable 42~58VDC telecom voltage with max rated 3000W/61A output power. Equipped advanced DSP digital control technology, it features ultra-high MPPT tracking precision over 99.5% and peak conversion efficiency above 98%, realizing preferential solar power supply to cut grid and diesel fuel cost. Standard hot-swap plug-in structure can be mixed installed together with AC rectifiers inside same power shelf without cabinet modification, widely applied in remote 4G/5G base station, pole-mounted FTTx OLT cabinet and rural off-grid solar transformation projects.
Key Features
Wide PV input range:58~150VDC(nominal68VDC), withstand max 165VDC static open-circuit PV voltage, match multiple series solar panel combinations
Adjustable DC output:42~58VDC(default53.5VDC), max61A/3000W constant power output, precise voltage regulation≤±0.6%
Ultra-high MPPT tracking efficiency ≥99.5% under rated load, maximize solar panel power harvest to reduce energy waste
Peak conversion efficiency＞98%, intelligent variable speed fan cooling to lower idle power consumption and operating noise
Full hot-swap drawer design, online replace module without whole cabinet power shutdown for easy maintenance
Complete multi-protection:PV reverse connection prevention, OVP/UVP/OCP/SCP/OTP + PV side lightning surge protection
Built-in CAN bus communication, real-time data sync with cabinet monitor for PV generation statistics and remote fault alert
Stable full-power output from -20℃~+55℃, power derating above 55℃, adapt high-temperature outdoor sealed pole cabinet
