Atmoce MC100 Single-Phase M-Combiner | Solar Battery Grid Management Hub

Description

The Atmoce MC100 single-phase M-Combiner is the central management hub of the Atmoce home energy system, bringing together solar microinverters, battery storage, and the grid connection in a single pre-wired, pre-installed enclosure. It supports up to 10kW of PV power across two branches and up to 21kWh of battery capacity, making it suitable for the majority of residential single-phase installations.

Built into an IP65-rated, reinforced-insulation enclosure for indoor or outdoor mounting, the MC100 arrives pre-connected with its integrated M-Gateway MG100 controller, allowing installers to complete system activation quickly through the Atmozen app.

Please Note: The MC100 is designed for single-phase installations only. For three-phase properties, use the MC100-T; for smaller single-phase systems up to 5kW PV, the compact MC100L Lite may be more appropriate.

Integrated System Hub Combines the gateway, grid interface relay, current sensors and power breakers in one unit, managing the interaction between microinverters, batteries, loads, and the grid connection.	High Power Capability Rated for 10kW of PV power across two branches, 21kWh of battery capacity, and 7kW of load power, comfortably covering most residential solar-plus-storage arrays.	Pre-Installed & Pre-Connected Ships with the M-Gateway MG100 already fitted, along with pre-wired breakers and current transformers, so on-site work is limited to final connections and app activation.
Bi-Directional Cloud Communication Communicates with Atmoce-Cloud and the Atmozen app via PLC, Wi-Fi, BLE, ETH, CAN and RS485, giving installers and homeowners remote visibility of system performance.	Reinforced Safety Design An IP65-rated enclosure with reinforced insulation and Class II protection supports both indoor and outdoor installation, with a Type III overvoltage rating for grid-side protection.	Precision Metering Includes current transformers accurate to within 0.1% for both microinverter and battery monitoring, feeding accurate real-time production and consumption data to the Atmozen app.

What does the MC100 do within an Atmoce system?

The MC100 is the central hub that safely connects and manages the interaction between solar microinverters, battery storage, the grid connection, and home loads, using its integrated M-Gateway to control and monitor the whole system.

How much solar and battery capacity can the MC100 support?

The MC100 supports up to 10kW of PV power across two branches and up to 21kWh of connected battery capacity, suitable for most single-phase residential installations.

Does the MC100 come with the gateway already fitted?

Yes. The unit ships pre-installed and pre-connected with the M-Gateway MG100, along with its breakers and current transformers, so installation is largely a case of making final wiring connections and activating the system in the Atmozen app.

Is the MC100 suitable for outdoor installation?

Yes. It carries an IP65 environmental rating with reinforced insulation, making it suitable for both indoor and outdoor mounting.

What is the difference between the MC100 and the MC100L?

The MC100 supports up to 10kW of PV power and 21kWh of battery capacity across two PV branches, while the MC100L Lite is a smaller single-branch unit rated for up to 5kW PV and 7kWh of battery capacity, suited to more compact systems.
