Deye LV 14kW Three Phase Hybrid Inverter - SUN-14K-SG05LP3-AU

Overview

The SUN-14/15/16/18/20K-SG05LP3-AU-SM2 Series is a modern range of three-phase hybrid inverters delivering outputs from 14 kW to 20 kW. Designed specifically for Australian residential and light commercial energy storage systems, this series combines high performance, intelligent energy management, and advanced low-voltage battery integration.

Supporting 48 V low-voltage batteries with a transformer-isolated design, these inverters provide enhanced electrical safety, very high battery current capability, and flexible hybrid operation. Features such as unbalanced three-phase output, AC coupling, and programmable battery scheduling make this series suitable for both new installations and retrofit projects.
