The Atmoce MG100 M-Gateway is the intelligent controller at the heart of every Atmoce home energy system, enabling seamless communication between microinverters, batteries, and home smart devices. With capacity for up to 90 connected microinverters and simultaneous Bluetooth and Wi-Fi communication, the MG100 gives installers and homeowners real-time visibility of energy production, consumption, and system status.
Supporting six communication protocols — PLC, Wi-Fi, ETH, BLE, RS485 and CAN — the MG100 is designed for pre-installed, pre-connected setup and quick activation through the Atmozen app, forming a mandatory core component of the Atmoce M-Combiner range.

Important Safety Information: The M-Gateway is a mandatory component of the Atmoce system and must be installed within a combiner enclosure that meets IP65 ingress protection standards; the MG100 itself carries only IP30 protection and is not designed for stand-alone outdoor exposure.
System-Wide Coordination
Enables seamless communication between microinverters, batteries, and home smart devices, letting users optimise power usage and track energy production from a single point.
|
High Microinverter Capacity
Supports up to 90 connected microinverters per gateway, suiting both single unit residential arrays and larger multi-array installations.
|
Simultaneous Wireless Communication
Provides simultaneous Bluetooth and Wi-Fi connectivity alongside PLC, ETH, RS485 and CAN interfaces for flexible integration into different system layouts.
|
Pre-Installed & Pre-Connected
Ships pre-installed and pre-connected within Atmoce combiner units, with easy system activation available through the Atmozen app.
|
Remote Energy Management
Supports remote management of home electricity via bi-directional communication with Atmoce-Cloud, allowing performance monitoring from anywhere.
|
Compact, Low-Power Design
A lightweight 0.6kg unit drawing under 20W keeps the gateway's footprint and running cost minimal within the wider system.

What is the role of the MG100 in an Atmoce system?
The MG100 is the intelligent controller that manages communication between microinverters, batteries, and home devices, giving users real-time visibility of energy production and consumption via the Atmozen app.
How many microinverters can a single MG100 support?
A single MG100 gateway supports up to 90 connected microinverters, covering the vast majority of residential rooftop arrays.
Can the MG100 be installed outdoors on its own?
No. The MG100 itself carries only IP30 protection and must be installed within an Atmoce combiner enclosure that meets IP65 ingress protection standards; it is not designed for stand-alone outdoor exposure.
Is the MG100 sold separately or only within combiner kits?
The MG100 can be purchased as a standalone replacement or spare unit, though it is also pre-installed within Atmoce MC100, MC100-T and MC100L combiner units as standard.
What communication methods does the MG100 support?
The MG100 supports six communication methods: Power Line Communication (PLC), Wi-Fi, Bluetooth Low Energy (BLE), Ethernet (ETH), CAN, and RS485, providing flexibility for different installation setups.
