The Atmoce MA-ESS-T Kit is a three-phase retrofit solution that allows an Atmoce M-ELV battery to be added to an existing solar installation running a third-party PV inverter, without needing to replace or reconfigure the existing generation equipment. The kit is built around the M-Gateway MG100, which manages system performance and communicates with the ATMOCE Cloud and ATMOZEN app so users can monitor home energy production and consumption alongside their new battery storage.
Supplied with pre-labelled current transformers and cable adapters for fast, accurate installation, the MA-ESS-T Kit is designed to bring battery storage to three-phase properties of any age, independent of the existing PV system's brand or inverter type.

Please Note: The MA-ESS-T Kit is designed to retrofit Atmoce M-ELV batteries onto systems using third-party PV inverters. It is not a replacement for the Atmoce M-Combiner range and does not include a battery unit — batteries must be ordered separately.
Third-Party Inverter Compatible
Lets installers add an Atmoce M-ELV battery to an existing three-phase PV system, regardless of the age or brand of the original solar inverter.
|
Gateway-Managed Control
Built around the M-Gateway MG100, which intelligently manages system performance and handles communication with ATMOCE Cloud and the ATMOZEN app.
|
Scalable Battery Capacity
Supports the connection of up to 18 Atmoce batteries per gateway, allowing storage capacity to be scaled to match the property's energy needs.
|
Pre-Labelled For Fast Installation
Individual cable adapter cores are clearly labelled, helping installers complete wiring quickly and accurately on-site.
|
Simple Retrofit Wiring
Includes split-core current transformers for battery and PV generation monitoring, plus a grid CT that connects directly to the gateway.
|
Remote Monitoring & Control
Once commissioned, the system is managed through the ATMOCE Cloud and ATMOZEN app, giving homeowners visibility of production, consumption, and battery status.

What does the MA-ESS-T Kit include?
The kit includes an M-Gateway MG100, a battery current transformer, a PV generation current transformer, a grid current transformer that plugs directly into the gateway, and two labelled cable adapters for easy connection.
Does the kit work with any solar inverter brand?
Yes. The MA-ESS-T Kit is specifically designed for retrofitting an Atmoce M-ELV battery onto three-phase systems running third-party PV inverters, regardless of the original inverter's brand or age.
Is the battery included in this kit?
No. The MA-ESS-T Kit provides the gateway and monitoring hardware needed to add battery storage; Atmoce M-ELV battery units must be ordered separately.
How many batteries can be connected to one kit?
Up to 18 Atmoce batteries can be connected to a single M-Gateway, allowing the system to be scaled to suit the property's storage requirements.
Is there a single-phase version of this kit?
This listing covers the three-phase MA-ESS-T kit; a corresponding single-phase MA-ESS kit is also available for single-phase properties.
