Adjusting Charge Rate On-Demand via the Emporia Energy App
You can manually adjust the charge rate at any time in the app. There are two key settings: When determining the charge rate, it is essential to follow the 80% rule for circuit breaker compatibility. This means the charger's amperage should not exceed 80% of the breaker's capacity, ensuring safe and efficient operation.
Maximum Charge Rate – A permanent ceiling to ensure safe operation based on your electrical system
Real-Time Charge Rate – A dynamic setting that allows on-the-fly adjustments in single-amp increments (6A–40A for NEMA 14-50, up to 48A if hardwired) These settings are crucial not just for operational flexibility but also to ensure the charger's amperage aligns with the electrical panel’s capacity, which reduces safety risks and inefficiencies.
To adjust the Maximum Charge Rate:
Tap the Electric Pump icon next to your charger’s name
Open Settings by tapping the Charger Settings tile at the bottom of the page
Select Breaker
You can select the appropriate breaker size. Selecting the correct breaker size ensures that the charging setup aligns with its capacity. The Emporia app helps you adjust the setup automatically based on the chosen breaker. For instance, with a 50-amp breaker, the maximum continuous current should be 40 amps, adhering to the 80% safety rule.
To adjust the Real-Time Charge Rate:
Tap the Electric Pump icon next to your charger’s name
Tap the Charger Settings tile at the bottom of the page
Tap Charge Rate from the settings list
Automated Energy Management
The Emporia platform offers smart features to adjust charge rates for efficiency and cost savings automatically:
Excess Solar Optimization – Adjusts the charge rate to maximize solar energy usage
Peak Demand Management – Modulates charging to reduce peak demand charges
Load Management – Balances electrical load to prevent system overloads
Limitations to Consider
Vehicle Limitations – Some EVs have a maximum charge rate that cannot be exceeded. Always check the EV's specifications, as not all vehicles support the charger’s maximum amperage. Tailor the amperage settings accordingly to avoid compatibility issues. Always consider applying the 80% rule when determining safe and effective charge settings. Consulting a professional for complex setups ensures adherence to safety standards and electrical system compatibility.
System Limitations – Your home’s electrical setup may impose restrictions
Installation Limitations –
40A max for NEMA 14-50 plug installations
Up to 48A if the charger is hardwired- Hardwiring versus Outlet Usage – Hardwiring the charger can eliminate reliance on outlets, reducing failure points and increasing reliability, especially for high-powered and long-term use cases. Alternatively, upgrading to outlets explicitly rated for Level 2 chargers can also enhance performance and safety.
PIN Requirement (NEC Compliance)
The National Electrical Code (NEC) requires a PIN to change the breaker size for safety. The installer sets this PIN. Contact them or Emporia Support for resets
Safety Note
Always ensure your charge rate matches your electrical system’s capacity. Incorrect settings may cause safety hazards—consult a professional for adjustments requiring a PINFor installation tasks such as converting from a NEMA 14-50 configuration to a hardwired setup, professional assistance is strongly recommended. A qualified electrician ensures compliance with safety standards and reduces risks associated with incorrect setup. Exceeding the safe amperage setting can lead to tripped breakers, overheating, or potential hazards. Always reduce settings conservatively if unsure, and prioritize professional guidance to avoid risks.
