Diagnostic LEDs
- The diagnostic LEDs provide a per-phase indication of power (green flashing) and negative power (red flashing) to help troubleshoot connection problems, like swapped CTs, or excessive line voltage. See the manual for a full description.
Advanced Output Capabilities are available as factory options:
- Standard output provides pulses on one terminal for positive energy and on another terminal for negative energy. This is useful with solar panels, where energy taken from the grid and energy fed to the grid can be metered separately with one meter (net metering).
- For more information on available options click the Options tab.
