Required Hardware
Emporia Energy Monitor (Vue 3 or Vue 2 with 200A CTs on mains)
Emporia Classic or Pro EV Charger- Install the Vue Energy Monitor with 200A CT sensors on the main lines between your utility and solar power source to precisely determine energy flow.
Verify Configuration
Open the Emporia Energy App
Tap Discover → Excess Solar Management
Verify that your energy monitor shows Enabled status
Check that all devices have automation enabled (the toggle should be green)
Verify device priority order matches your preferences
EV Charger Setup Requirements
Navigate to your EV charger in the app.
Tap the "Pause" button to disable immediate charging. This mode enables charging only when excess solar energy is available. Pause Mode: Ensures the charger operates automatically based on a confirmed 1.5 kW excess solar output.
Plug in the EV charger while in "Pause" mode.
Minimum 1.5 kW excess solar power for EV charger activation.
Net production status for 3+ minutes (generating more than consuming).
If using a solar battery system like Tesla Powerwall, configure the battery settings to disable power supply to the EV charger circuit and align the load-following feature to solar output.
Common Troubleshooting
EV Charger Not Activating:
Confirm the charger is in "Off" mode - prior to plugging into the EV
Verify excess solar ≥1.5 kW for 3+ minutes
Check device priority settings
Ensure stable network connectivity.
Verify that the Vue monitor's CT sensors are correctly placed upstream of your solar production to avoid inaccurate readings.
"Excess Solar Has Been Overridden"
Open Excess Solar Management in the app
Toggle the excess solar feature off
Toggle the excess solar feature back on
This clears the override and restores normal operation
Troubleshooting and Support
The Excess Solar Management feature requires proper installation and configuration of your energy monitor and controllable devices. While most setups are straightforward, some fine-tuning may be needed for optimal performance.
