Product Overview
The Huawei S4850G1 is professional built-in MPPT DC-DC solar converter exclusively customized for Huawei EN3M61SSUA01 outdoor integrated telecom cabinet and ETP48400 series power systems. Designed to convert variable solar PV DC voltage (58~150VDC) into stable adjustable 43.2~58VDC standard telecom voltage(default53.5VDC), rated max output 3000W/52A(50A nominal). Featured industry-leading ≥99.8% MPPT tracking efficiency above 100W load and peak conversion efficiency up to98.2%, it automatically locks PV maximum power point to maximize solar harvesting and reduce diesel & grid power consumption for remote unmanned communication sites. Standard drawer hot-swap structure enables direct plug-and-play installation inside EN3M61SSUA01 cabinet without structural modification, widely deployed in rural off-grid 4G/5G pole base station and FTTx outdoor OLT cabinet solar transformation projects。
