ZECO Energy is proud to announce a major technical milestone: the successful installation of its Marshall device in a Sigenergy PV system within the AusNet network.
This breakthrough brings a practical solution to one of the key challenges faced by homeowners and businesses using Sigenergy inverters in Victoria: compliance with the state’s Emergency Emergency Backstop Mechanism. Marshall bridges this critical gap.
ZECO engineers worked closely with industry partners to ensure that Marshall can act as the certified gateway device, interpreting signals from DNSPs and coordinating appropriate inverter response in real time — even in complex systems involving battery storage.
“We’ve worked hard to develop and certify Marshall for compatibility with multiple inverter brands. With these integrations, customers get the best of both worlds — smart solar tech and full regulatory compliance in a system that overcomes all the Backstop problems."
Jag Makam, Director of ZECO Energy.Marshall, ZECO’s advanced Technology, is already trusted by installers nationwide for its robust export control, system monitoring, and load management capabilities.
Its unique ability to adapt across protocols and inverter types has made it a go-to choice for systems requiring flexible integration — and now, that includes Sigenergy.
The newly certified setup enables:
For energy providers, solar installers, and homeowners alike, this is a game-changer.
Marshall is available in multiple formats (Lite, Blackbox, and Blackbox Ultra) to suit residential and commercial systems. It can be purchased via ZECO or Tradezone.

ZECO Marshall is a dynamic export control and energy management product that optimises solar energy usage. It allows flexible energy exports, supports load control, and integrates with solar inverters, energy meters, and smart devices through our unique hardware and software solution.
ZECO Marshall is used for:
ZECO offers three main Marshall products:
Marshall Lite – A compact, essential-feature version for dynamic export control.
Marshall Blackbox – Comprehensive control and monitoring capabilities, includes a single-phase meter.
Marshall Blackbox Ultra – Includes an integrated three-phase meter for detailed energy insights.
ZECO Marshall supports most major inverter brands and is compatible with SAPN, ENERGYQ, and Victorian DNSPs (AusNet, United Energy, Jemena, Powercor, Citipower).
Overload Control prevents household and commercial overload by monitoring energy import amperage. If the current exceeds the main switch rating, ZECO Marshall trips non-essential loads to keep the system within safe limits. This feature is particularly useful for preventing residential system trips.
ZECO Marshall devices are designed for easy installation. Refer to the installation manuals for more details. They can be connected via LAN, Wi-Fi, or RS485, depending on the setup. A licensed installer should handle the installation to ensure proper integration and compliance.
While an internet connection is recommended for real-time monitoring and firmware updates, ZECO Marshall can operate in a local network environment with limited cloud dependency.
Yes, ZECO Marshall devices are Clean Energy Council (CEC) certified, Australian Made and comply with relevant Australian energy regulations for export control and metering.
Users can monitor and control Marshall devices through our web portal or mobile app, allowing access to energy data, export settings, and load control features remotely.
Yes, Marshall supports both residential and commercial solar installations, making it ideal for larger energy management applications.
