Avoid Costly Electrical Panel Upgrades with PowerSmart
Yes, for most customers faced with a costly electrical system upgrade, we can help.
Installing an EV charger may reveal that your electrical panel lacks sufficient power capacity, potentially requiring an expensive upgrade. PowerSmart by Emporia Energy offers an alternative solution.
PowerSmart automatically controls your EV Charger load in compliance with NEC regulations, eliminating the need for costly electrical system upgrades. Both the EV Charger and Vue monitoring devices are UL-certified for safety.
Single Charger Cost Savings
While a typical panel upgrade from 100A to 200A can cost $1,000-$5,000 or more, our PowerSmart solution costs just $600 total.
Multi-EVSE Panel Capacity Management
Enhanced Load Management with Multiple Chargers
PowerSmart's multi-EVSE support significantly increases your ability to avoid expensive panel upgrades. Here's how:
PowerSmart intelligently balances the load across multiple EV Chargers, dynamically adjusting charging rates based on your home's real-time energy usage. This means you can install multiple high-capacity chargers without exceeding your panel's limits.
