Grizzl-E Ultimate 48A Level 2 EV Charger – Professional Review

The Grizzl-E Ultimate 48A is a high-power, hardwired Level 2 EV charger built for users who prioritize durability, electrical safety, and long-term reliability over minimal aesthetics or plug-and-play convenience.

Charging Performance & Electrical Capacity

• Maximum Output: 48A / 11.5 kW
• Up to 9× faster than a standard 120V Level 1 charger
• Compatible with all J1772 EVs (Tesla requires adapter)

At 48 amps, the Grizzl-E Ultimate delivers charging speeds comparable to premium residential stations while remaining compliant with NEC hardwired installation standards.

Hardwired-Only Design: Why It Matters

Unlike plug-in EVSEs, this model is hardwire-only, which provides several technical advantages:

• Lower contact resistance
• Reduced heat generation
• Higher long-term reliability
• Improved compliance for 48A continuous loads

The included hardwire kit (terminal lugs and heat-shrink wrap) simplifies installation and ensures a clean, code-compliant connection.

Industrial-Grade Construction (Made in Canada)

The charger features a UL Type 4 rated aluminum cast enclosure, designed to withstand:

• Rain, snow, sleet, and dust
• Extreme temperature swings
• Mechanical stress in garages or outdoor mounts

This is a charger built for long service life, not lightweight consumer plastics.

Certifications & Safety Protections

• UL Certified
• Energy Star Certified
• Full electrical protection suite
• 3-year manufacturer warranty

These certifications ensure compliance with North American electrical safety and efficiency standards.

Smart Charging & Connectivity

Powered by Grizzl-E Connect, the charger supports:

• Real-time charging monitoring
• Scheduling and energy usage statistics
• Diagnostics and firmware updates

Importantly, charging continues even without an active internet connection, ensuring reliability during network outages. An external antenna improves Wi-Fi stability in garages and basements.

Advanced Load Balancing & OCPP Support

The Ultimate model supports intelligent power distribution across multiple chargers:

• Equal sharing for balanced usage
• Priority charging for a primary vehicle

Optional premium OCPP activation enables future-ready integration with energy management systems, fleets, or smart infrastructure (one-time activation fee applies).
