The Microgeneration Certification Scheme (MCS) has a classification system for Electrical Energy Storage Systems (EESS) outlined in standard MIS 3012. This system categorises battery storage solutions into four classes based on how the components—such as the batteries and inverters—are integrated and sourced.
MCS Battery Classification:
- Class 1 – All components are enclosed within a single unit, with no exposed direct current (DC) cabling.
- Class 2 – The battery modules and inverter are housed in separate enclosures but come from the same manufacturer and are connected by DC cabling.
- Class 3 – The battery modules and inverter are from different manufacturers, requiring compatibility checks by the installer.
- Class 4 – All components, including batteries, safety devices, and inverters, are sourced from different manufacturers and must be configured by the installer to ensure safe and effective operation.
How This Applies to FoxESS Systems
At FoxESS, we offer two main battery ranges: the ECS and EP models. When paired with a separate Fox inverter—such as the H1, K, H3, or H3 Pro—these systems fall under MCS Class 2, as the batteries and inverter are designed to work together but are housed separately and connected by DC cabling.
The exception is our PowerQ model, which is an all-in-one unit with no external cabling between the inverter and batteries. This means it falls into a different classification, aligning more closely with MCS Class 1.
By understanding MCS classifications, installers and customers can ensure compliance with industry standards while selecting the most suitable storage system for their needs.
