Overview
Expanded Monitoring
Firmware Version is 5.557 - Click here to see the release notes.
Expanded Monitoring
With this update, CT2 and CT3 can now be used in 3-phase zappi installations on single-phase supplies. This enables the simultaneous monitoring of multiple energy circuits, providing more comprehensive data and management.
Auto-Detection
The zappi now automatically detects the supply type (single-phase or three-phase) and adjusts CT functionality accordingly (see "Technical Considerations" below).
Enhanced Admin Portal Visibility
Monitoring and setup options for single-phase installations are now more visible and manageable in the admin portal.
Key Benefits
When installing a 3-phase zappi on a single-phase supply, please note the following configurations:
- CT1: Bi-directional readings.
- CT2: Uni-directional readings (typically used for generation or solar monitoring).
- CT3: Bi-directional readings.
Important: The CT setup must follow these new configurations to ensure proper monitoring.
CT Functionality
A new label will be introduced, indicating the zappi’s compatibility with both single-phase and three-phase supplies.
Product Labelling
Transitioning from a 3-phase to a single-phase installation will be clearly indicated in product documentation and labelling.
Technical Considerations
CT Auto-Adjustment
-
For configurations where all CTs are set to the same group (e.g., “none,” “generation,” or “storage”)
- The system will not make changes.
- Example: Gen, Gen, Gen = Gen, Gen, Gen
-
For configurations with mixed settings
- The system will automatically set CT1 as the primary CT and configure CT2 and CT3 as “none.”
- Example: Grid, Grid, Grid = Grid, None, None
Transition from Single-Phase to 3-Phase Installation
-
If one CT is set to an energy group and the other two are set to “none”
- The system will match all three CTs to the active one.
- Example: Grid, None, None = Grid, Grid, Grid
-
If all three CTs are already configured identically
- No changes will occur.
- Example: Storage, Storage, Storage = Storage, Storage, Storage
-
If each CT is configured differently
- All CTs will reset to “none,” and the installer must manually choose and complete the setup.
- Example: Grid, Solar, Battery = None, None, None
