The Atmoce MC100-T three-phase M-Combiner is the central management hub for larger Atmoce home energy systems, integrating solar microinverters, battery storage, and the three-phase grid connection within a single pre-wired, pre-installed enclosure. It supports up to 30kW of PV power across two branches and up to 42kWh of battery capacity, making it suitable for larger residential and small commercial three-phase installations.
Housed in an IP65-rated, reinforced-insulation enclosure suitable for indoor or outdoor mounting, the MC100-T arrives pre-connected with its integrated M-Gateway MG100 controller, streamlining installer setup and system activation via the Atmozen app.

What does the MC100-T do within an Atmoce system?
The MC100-T is the central hub for three-phase Atmoce systems, safely connecting and managing the interaction between solar microinverters, battery storage, the three-phase grid connection, and home loads via its integrated M-Gateway.
How much solar and battery capacity can the MC100-T support?
The MC100-T supports up to 30kW of PV power across two branches and up to 42kWh of connected battery capacity, suited to larger three-phase residential and small commercial installations.
Can the PV-side breaker be upgraded for higher power?
Yes. The standard configuration uses a 20A PV-side breaker, which installers can replace with a 25A-rated breaker to unlock the full 30kW maximum PV power rating.
Does the MC100-T come with the gateway already fitted?
Yes. The unit ships pre-installed and pre-connected with the M-Gateway MG100, along with its three-phase breakers and current transformers, reducing on-site installation time.
Is the MC100-T suitable for outdoor installation?
Yes. It carries an IP65 environmental rating with reinforced insulation, suitable for both indoor and outdoor mounting.
