200A Main Service Breaker Included

The Canadian Solar EP Cube Smart Gateway SGNA2-200GX is the control and interconnection hub for EP Cube hybrid solar plus storage systems, designed to deliver seamless whole-home energy management with reliable backup performance. Built for split-phase residential service, it supports 240/208V AC operation with a 200A maximum current rating, making it an ideal solution for main panel integration, backup loads control, and microgrid-ready operation. 

With seamless on-grid to off-grid switchover, the Smart Gateway helps keep critical loads powered during outages when paired with EP Cube batteries and the hybrid inverter. It also adds expansion and integration flexibility through an AC extend interface that supports generator control (2-wire start) and RS485 EV charger communication, plus support for up to 5 smart breakers for circuit-level control and future system growth. Built for durability, it features a NEMA 3R enclosure for robust protection and quiet operation at <30 dB(A) @ 1m, plus long-term confidence backed by a 10-year system warranty.
