Product Overview
The Vertiv eSure S48-2000e3 is professional DSP-controlled MPPT solar converter module developed by former Emerson Vertiv, specially designed for telecom hybrid solar off-grid base station and retrofitting existing NetSure series 48V communication power cabinets. It converts variable high-voltage PV input (140~400VDC) into stable adjustable -42~-58VDC communication standard DC power, rated maximum 2000W/42A@48V, with industry-leading MPPT tracking efficiency over 99.5% and peak conversion efficiency up to 96.8%. Adopt standard hot-swap plug-in structure perfectly matching Vertiv NetSure series rack, multiple modules parallel expand capacity freely, realize priority solar power supply to reduce grid electricity consumption, widely used in remote unmanned 4G/5G sites, FTTx outdoor cabinet and rural off-grid communication projects.
Key Features
Wide PV DC input range:140~400VDC(extreme 120~420VDC), compatible multiple series solar panel combinations
Nominal DC output:-42~-58VDC(default53.5VDC), max 2000W/42A continuous output@48V, constant power design
Ultra-high MPPT tracking efficiency>99.5% above 350W load, maximize solar energy utilization
Peak conversion efficiency up to 96.8%, intelligent fan speed control for energy saving and low noise
Standard plug-and-play hot-swap design, directly installed into original NetSure cabinet without rack modification
Built-in CAN bus communication, real-time data sync with cabinet master monitor for remote PV yield statistics & fault alert
Full multi-protection: OVP/OCP/SCP/OTP + PV side anti-lightning surge protection for harsh outdoor environment
Intelligent energy management: preferentially consume solar power, auto switch to mains when insufficient PV generation
Wide working temperature:-40℃~+65℃, stable full-load operation for high-temperature outdoor pole cabinets
