Vertiv eSure S48-2000e3 MPPT Solar Converter | 48V 2000W PV Charge Module

Specifications

Product Overview

The Vertiv eSure S48-2000e3 (1S482000E3) is professional DSP-controlled MPPT solar DC-DC converter developed by former Emerson Vertiv, specially designed to be hot-plugged into all Vertiv NetSure series embedded power cabinets for hybrid solar telecom sites. It converts wide-range PV DC input (120~420VDC, nominal140~400VDC) into adjustable 42~58VDC standard telecom voltage with max 2000W/42A rated output. Featured ultra-high ≥99% MPPT tracking efficiency above 350W load and peak conversion efficiency up to 96.8%, it can be mixed installed together with R48-2000e3 AC rectifiers in same shelf, realizing priority solar power consumption to cut grid electricity cost for remote unmanned communication stations. Widely used in rural off-grid 4G/5G small cell, pole-mounted FTTx OLT cabinet and old telecom station solar energy-saving renovation projects.

Key Features

Ultra-wide PV input:120~420VDC(Standard 140~400VDC), flexible matching multiple series combinations of solar panels

Adjustable DC output:‑42~‑58VDC(default53.5VDC), constant power design with max 2000W/42A continuous output

MPPT tracking precision＞99% when load＞350W, maximize solar panel energy harvesting efficiency

Peak conversion efficiency up to 96.8%, intelligent variable-speed fan reduces idle power consumption and running noise

Fully interchangeable & hot-swap with R48-2000e AC rectifier, no cabinet modification needed for retrofitting existing NetSure power rack

Built-in CAN bus communication, real-time data synchronization with cabinet master monitor for PV generation statistics & remote fault alarm

Full multi-protection: PV overvoltage/undervoltage, output OVP/OCP/SCP/OTP plus PV side lightning surge protection

Wide working range:‑40℃~+65℃ full-power output below 2000m altitude, adapt high-temperature sealed pole cabinet environment

Compliant with GR-1089, CE, EN62477 international safety & EMC standards
