SRNE HESP48180UH3 Delivers 18kW Three-Phase Hybrid Solar Storage
Three-phase 120/208V buildings need an inverter that can carry real commercial loads. The SRNE HESP48180UH3 inverter is an 18kW, 48V hybrid solar storage inverter with three MPPT inputs, a separate generator port and up to 350A of battery charging. It is certified to UL 1741-2021 (UL1741SB) and IEEE 1547, and it can parallel up to 9 units for 162kW.
Why You'll Love The SRNE HESP48180UH3 Inverter
Big solar capacity. Three independent MPPTs take up to 36,000W of PV (1.6 times rated power) at up to 600V, with 40A per tracker for high-power modules.
Fast battery charging. Up to 350A of charge and discharge current on a 48V bank, with two battery inputs and BMS self-adaption for lithium.
Built for the grid and beyond. 200A bypass, anti-islanding, AC coupling, smart load output and time-slot charging to make the most of peak and off-peak rates.
Tough enough for outdoors. IP65 enclosure, -13 to 140°F operating range and a 5-year warranty.
Your life, with the SRNE HESP48180UH3 Inverter
Your shop runs on three-phase power. When the utility drops, the compressors, lights and registers keep going on stored solar. When rates peak in the afternoon, the batteries carry the load and your bill stays flat.
