NEP – 30kW | Neptune 30kW | 3 Phase String Inverter | 208 VAC

The NEP Neptune 30kW (NEP-30KW) is a high-efficiency, three-phase grid-tied string inverter specifically optimized for North American 208V commercial and industrial (C&I) grids. Delivering a maximum efficiency of 98.7% (CEC 98.3%), this inverter features 3 independent MPPTs with 2 string inputs each and an upgraded input current of 40A per MPPT, allowing it to support a 150% DC/AC oversizing ratio and high-power bifacial solar modules. It is engineered as a true “RSD-ready” solution, featuring a built-in NEP Rapid Shutdown Transmitter that natively pairs with NEP panel-level devices for NEC 690.12 safety compliance. Built for industrial durability, it includes a NEMA 4X (IP66) enclosure with C5-level anti-corrosion protection, integrated AFCI, built-in PID recovery to enhance module longevity, and intelligent I-V curve scanning accessible through the NEP “Galaxy” monitoring platform for granular, panel-level data visibility.
