PowerSmart dynamically adjusts your EV Charger's charging rate to prevent panel overloading by monitoring system usage with an Emporia Energy Monitor. This allows the installation of a 48A EV Charger without electrical service panel upgrades. PowerSmart can manage single or multiple EV Chargers simultaneously.
To enable this feature, ensure you purchase the PowerSmart software for your charger if required and install the Vue Energy Monitor to monitor your panel's energy consumption. Both Pro and non-Pro models of chargers are compatible with PowerSmart.
Pre-requisites for PowerSmart Setup
Before proceeding to set up PowerSmart, ensure the following:
Obtain the PowerSmart software for your charger. Purchase may be required to enable this feature.
Install the Vue Energy Monitor to monitor the electrical panel that the EV Charger is wired to.
Confirm the Service Rating of the panel to ensure PowerSmart can manage the maximum current.
Configuration Settings
Enabled: Toggle to activate/deactivate PowerSmart. Recommended to keep enabled when PowerSmart is required
Energy Monitor: Select your Vue: Gen 2 or Vue: Gen 3 device to monitor your system's energy consumption
Service Rating: Enter your electrical service panel's amperage rating (typically your main breaker size, e.g., 100A, 150A, 200A)
Minimum Guaranteed Charge Rate: Specify the available amperage in your service panel before installation of the EV Charger. PowerSmart will allow the charger to draw up to this amount regardless of real-time Energy Monitor measurements
PowerSmart for Multiple Chargers
Minimum Guaranteed Charge Rate: Total amperage available for all EV charging across your panel. PowerSmart will distribute this capacity among active chargers
Individual Charger Limits: Each charger maintains its maximum charge rate setting, which PowerSmart will not exceed even when capacity is available
Dynamic Distribution: When multiple EVs are charging, available power is automatically distributed based on:
Equal sharing among chargers with the same service rating
Proportional allocation based on individual charger ratings
Real-time adjustments as vehicles complete charging or are plugged in
System Requirements for Multi-EVSE
All chargers must have PowerSmart capability or an upgrade
A single Vue energy monitor can manage multiple chargers
The electrical panel must have sufficient total capacity for the minimum charging requirements (6A per charger minimum)
All chargers must be on the same electrical panel being monitored
