What Is The Emporia EV Charger?
The Emporia EV Charger is a Level 2 electric vehicle charger offering 240V AC charging at up to 48A (11.5 kW), designed for residential and light commercial use. It features Wi-Fi connectivity for smart scheduling, energy monitoring via the Emporia Vue energy management ecosystem, and UL certification for safety. Its modular design allows hardwired or NEMA 14-50 plug installations, competing with ChargePoint and JuiceBox while prioritizing cost-efficiency and user-friendly app controls.

What defines the Emporia EV Charger’s core functionality?
Emporia EV Charger operates as a Level 2 J1772-compliant unit, delivering 240V AC power through SAE J1772 connectors. Its dynamic load management syncs with home energy usage to prevent circuit overloads. Snippet: Built for 48A continuous output, it charges EVs 6x faster than Level 1 chargers, with app-controlled scheduling to leverage off-peak electricity rates.
The Emporia charger’s 48A maximum output requires a 60A circuit breaker (NEC 80% rule), translating to ~44 miles of range per hour for a Tesla Model Y. Pro Tip: Pair it with Emporia’s Vue energy monitor to balance EV charging with household loads like HVAC systems. For example, during peak demand, the charger automatically throttles to 32A if the home’s total load exceeds 200A. Technical specs include IP65 weather resistance for outdoor use and a 24-foot cable with auto-retract. But what happens if your panel lacks capacity? The charger’s load-sharing feature can sync with multiple units, prioritizing charging based on predefined hierarchies. Warning: Never install on circuits with shared GFCI outlets—nuisance tripping may interrupt charging sessions.
How does the Emporia EV Charger handle smart connectivity?
Through Wi-Fi and Zigbee, the Emporia charger integrates with smartphones and home energy systems. Its app provides real-time kWh tracking, cost calculations, and firmware updates. Snippet: Users set charging windows to align with solar production or utility time-of-use rates, reducing energy bills by up to 30%.
The Emporia app (iOS/Android) displays session history, including exact charging times and energy sources. For solar users, the charger can delay charging until PV panels generate surplus power. Pro Tip: Enable “Departure Time Charging” to ensure the battery reaches 80% precisely before your commute. Technical protocols include OCPP 1.6 compatibility, allowing future integration with public charging networks. A real-world example: A household with a 10kW solar array uses the charger’s “Solar Only” mode to divert excess energy to their Nissan Leaf, achieving net-zero charging. However, weak Wi-Fi signals can disrupt remote commands—always test signal strength at the installation site. Transitioning to hardware, the charger’s 7-inch LCD shows voltage, amperage, and error codes like ground fault or over-temperature alerts.
| Feature | Emporia EV | ChargePoint Home Flex |
|---|---|---|
| Max Current | 48A | 50A |
| Cable Length | 24 ft | 23 ft |
| Price | $499 | $699 |
What installation requirements apply to the Emporia EV Charger?
Installation demands a 240V circuit (40A–60A), with hardwired or NEMA 14-50 plug configurations. NEC 625-compliant wiring and grounding are mandatory. Snippet: Professional installation is recommended due to high-voltage risks, though DIYers can attempt plug-in setups if local codes permit.
The charger’s manual specifies 6 AWG copper wires for 48A operation and 8 AWG for 40A. Pro Tip: Use a GFCI breaker even if not required locally—it adds a layer of protection against ground faults. For hardwired installations, torque terminals to 25 lb-in to prevent arcing. A case study: A Tesla owner in Colorado saved $300 by self-installing the plug-in version but later paid $150 for an electrician to upgrade to 48A hardwired. Transitionally, municipalities like Los Angeles require permits for EV charger installations, adding $50–$200 to project costs. Always check whether your utility offers rebates; Con Edison in NY provides $500 for Emporia units. Warning: Avoid using aluminum wiring—higher resistance causes voltage drops and fire hazards.
| Configuration | Breaker Size | Wire Gauge |
|---|---|---|
| Plug-in (40A) | 50A | 8 AWG |
| Hardwired (48A) | 60A | 6 AWG |

FAQs
Yes, via the J1772-to-Tesla adapter included with all Tesla models. Charging speed caps at 48A (11.5 kW), matching Tesla’s Mobile Connector.
What’s the warranty period?
Emporia offers a 3-year limited warranty, covering defects in materials and workmanship. Exclusions include physical damage or improper installation.
Can it charge two EVs simultaneously?
No—each Emporia unit serves one vehicle. For dual charging, install two chargers with load-sharing enabled via the app.
