The Grizzl-E Smart Level 2 EV Charger (240V, 40A) is a budget-friendly smart EV charger with a rugged aluminum build, J1772 compatibility, UL-listed, Energy Star certified, and NEMA 14-50/6-50 plug support.
The Grizzl-E Smart EV Charger takes the tough, reliable design of the Classic model and adds smart features that actually save you money. It uses OCPP 1.6 technology to connect with apps like ChargeLab and the company’s own Grizzl-E Connect app. You get remote monitoring, scheduling, and energy tracking without giving up the rugged durability that made the original Grizzl-E Classic popular.
We first came across the Grizzl-E line while looking for a tough, off-road-ready EV charger, and it didn’t disappoint. We used the Grizzl-E Classic with our Jeep 4xe and can confirm it holds up better than most in harsh conditions. This charger isn’t the smartest option on the market, considering now we have AI smart EV chargers such as the Autel MaxiCharger 80A EV Charger, but it’s perfect for homeowners who want a durable, smart charger at an affordable price. If you’re also looking for serious long-term value and flexibility, the Grizzl-E Smart delivers.
How It Compares to the Competition
The Grizzl-E Smart goes head-to-head with DEWALT EV Chargers, which offer similar rugged, weatherproof designs. DEWALT adds both Bluetooth and Wi-Fi connectivity, targeting customers who trust the American brand name and want extra safety features. Both options give you tough outdoor performance combined with intelligent charging management, so your choice might come down to brand preference and specific features you need.
Smart Features That Actually Save You Money
The Grizzl-E Smart charger connects to apps like Grizzl-E Connect or ChargeLab to help you save money on electricity. The biggest savings come from scheduling your charging sessions during off-peak hours when electricity is cheapest. In places with Time-of-Use rates, like California or Ontario, peak electricity can cost three to five times more than off-peak rates.
By scheduling EV charging during off-peak TOU hours with the Grizzl-E Smart EV Charger, we reduced our monthly EV charging costs by roughly 20% (Our TOU EV charging strategy)
Tracking Time-of-Use savings manually is complicated, but the Grizzl-E Connect app makes it easy by working with smart home monitors on our EV circuit to show exactly when and how much we’re saving with every charging session.
You can also earn money through Demand Response programs. Many utility companies will pay you $50 to $150 per year just for letting your charger slow down during times when the power grid is stressed. Programs like OhmConnect make this easy, and the credits show up right on your electricity bill.
Freedom to Choose Your Software
The Grizzl-E Smart uses something called OCPP 1.6J, which is an open standard for EV chargers. This might sound technical, but it’s actually one of the charger’s best features for protecting your investment.
Most smart chargers force you to use only the manufacturer’s app. If that company goes out of business or changes its terms, your expensive charger becomes a basic “dumb” charger overnight. The Grizzl-E Smart is different because it works with multiple third-party software providers like ChargeLab and ev.energy.
You can switch between apps in just minutes if you want different features or better pricing. Since the average Level 2 charger should last over 10 years, this flexibility protects your Grizzl-E Smart EV charger investment for its entire lifespan. Your charger stays smart no matter what happens with any individual software company.
Avoiding Expensive Electrical Upgrades
One of the smartest features is load balancing, which can save you thousands of dollars upfront. Many older homes have 100-amp or 125-amp electrical panels. Adding a 48-amp EV charger usually means you need to upgrade your entire panel, which costs between $2,000 and $4,500.
The Grizzl-E Smart uses intelligent power sharing to avoid this problem. It automatically adjusts how much power it draws based on what else is running in your home. If your air conditioner or dryer turns on, the charger backs off to stay within your panel’s limits.
This technology can cut your total installation costs by more than 60% if your home has limited electrical capacity. You get a powerful Level 2 charger without the massive upgrade bill.
Flexible Installation Options
The Grizzl-E Smart works with your home’s setup. You can choose professional hardwire installation for a permanent solution, or go with the plug-in option using either a NEMA 6-50 or NEMA 14-50 outlet. This flexibility makes it easier to install, whether you’re in a new home or retrofitting an older one.
Setup Got Much Easier
When we first tested the Grizzl-E charger, the setup was frustrating. The third-party ChargeLab app had compatibility problems that made the experience harder than it should have been. Grizzl-E listened to feedback and built their own app called Grizzl-E Connect, which has completely changed the game.
The native Grizzl-E Connect app makes everything smoother. You can monitor your charging status, schedule sessions, and adjust settings without fighting with compatibility issues. What used to be a complicated setup is now straightforward and user-friendly. This improvement alone makes the Grizzl-E Smart a much better product than when it first launched.
Making the Most of Your Solar Panels
If you have a grid-tied EV charging set-up, the Grizzl-E Smart can work with energy management systems like Emporia to maximize your savings. Without this integration, you might sell extra solar power back to the grid for just five cents per kilowatt-hour, then buy it back at night for 25 cents.
Smart software fixes this problem by charging your EV directly with surplus solar energy during the day. Every kilowatt-hour you use from your own panels instead of the grid saves you 20 cents. If you have a typical solar surplus of 10 kilowatt-hours per day, this adds up to about $730 in extra savings each year.
NEMA 14-50R Outlet Installation for Grizzl-E Smart EV Charger
When I installed the NEMA 14-50R outlet for my Grizzl-E Smart EV Charger, the first thing I did was switch off power at the main panel, safety first. Then I added a dedicated 50-amp double-pole breaker to handle the load. Running 6 AWG feeder wires from the breaker to the outlet spot felt straightforward, but I made sure the wire length was kept tight to avoid unnecessary voltage drop.
The outlet itself has four terminals: two hot wires carrying 240V, one neutral, and one ground. I carefully stripped each wire just right; too much exposed copper can be dangerous, and too little makes a weak connection. Tightening the screws firmly was key because loose connections can cause heat buildup and damage over time.
Mounting the outlet solidly to the wall gave me confidence it wouldn’t wiggle or pull on the wiring. I used proper strain relief clamps to keep tension off the wires, which is often overlooked but super important for safety and durability.
Once everything was wired up, I tested the outlet with my Grizzl-E charger. The charger fired up smoothly, no hiccups or tripped breakers. One thing I keep in mind: always follow local electrical codes and regulations. Trust me, cutting corners here is not worth the risk.
A quick pro tip from my experience: when working with continuous loads like EV chargers, double-check that your breaker and wiring are rated correctly for 125% of the charger’s max current, per NEC Article 625. It’s a small detail that protects your investment and keeps everything running cool and safe.
