Enphase IQ System Controller 3 INT – 3-phase ATS

IQ System Controller 3 INT: the beating heart of your Enphase Energy System

Seamless transfer from grid to back-up during a power outage
The Enphase IQ System Controller 3 INT (SC100G-M230ROW) is the central connection and control point for your 3-phase Enphase solar power and home battery system. This smart switch box connects your home to the electricity grid, the IQ Battery 5P and the IQ7 or IQ8 Microinverters. Thanks to the integrated Automatic Transfer Switch (ATS), the system automatically detects a power outage and switches over to back-up power within 120 ms. With a maximum continuous current of 80 A per phase and support for both 3-phase and 1-phase configurations, this is the ultimate all-in-one solution for a future-proof energy installation.

Smart integration and wired communication

IQ Gateway, production and consumption CTs and IQ Relay in a single enclosure
The IQ System Controller 3 INT consolidates all the required interconnection equipment in one pre-wired enclosure: an integrated IQ Gateway monitoring plate, pre-wired production and consumption CTs on the PV and grid terminals, IQ Relay functionality and a Mobile Connect cellular modem with a 5-year data subscription for a back-up internet connection. The wired control communication provides a fast and reliable connection to the IQ Battery 5P. Via the Enphase App you have 24/7 insight into production, consumption and battery status, and you can monitor and operate the system remotely. The unit also supports 2× NO and 2× NC auxiliary contacts for PV shedding, integration of third-party string inverters and load control.

Robust design for Dutch conditions

IP55 polycarbonate enclosure with a 10-year manufacturer’s warranty
With a durable IP55 polycarbonate enclosure, the IQ System Controller 3 INT is suitable for both indoor and outdoor mounting and resistant to weather, dust and splash water. The wide ambient temperature range of -40°C to +50°C and natural convection cooling guarantee reliable operation in all Dutch weather conditions. The unit has room for 10 single-pole circuit breakers on the PV/battery side and 8 on the grid/back-up side, and supports conduit entry from below, behind, left and right. Enphase provides a 10-year manufacturer’s warranty on the System Controller and 5 years on the System Shutdown Switch and Mobile Connect.
