Smart vs Standard EV Chargers: What’s the Difference (and Which Is Right for You?)
As more homeowners switch to electric vehicles, one of the most common questions we’re asked is:
“Do I need a smart EV charger, or will a standard one do?”
At first glance, all EV chargers do the same job, i.e. they charge your car. But how they do it, and how efficiently they work alongside your home energy system, can vary significantly.
What is a standard EV charger?
A standard EV charger is the simplest type of home charging.
You plug your car in, and it starts charging immediately at a fixed rate. There’s no communication with your home energy system, no scheduling and no optimisation.
It’s reliable and does the job, but it’s essentially an on/off device.
This means:
- Charging often happens when electricity is most expensive
- It doesn’t respond to solar generation
- There’s no control over when or how energy is used
Standard chargers are generally lower cost upfront, but they don’t help you make the most of your energy.
What is a smart EV charger?
A smart EV charger is designed to do much more than simply charge your car.
It connects to your home, your energy tariff and often your solar system, allowing it to control when and how your vehicle charges.
Instead of charging immediately, it can:
- Charge at cheaper, off-peak times
- Adjust based on your household energy use
- Prioritise solar energy when it’s available
- Be controlled remotely via an app
In simple terms, it makes charging more efficient, more flexible and more cost-effective.
Why smart chargers work better with solar
This is where the difference really matters.
Without a smart charger, any excess solar energy your system produces is often exported back to the grid.
With a smart charger, that energy can instead be used to charge your car.
That means:
- More of your own energy is used at home
- Less electricity is bought from the grid
- The cost per mile of driving is reduced
Using your own solar energy is always more valuable than exporting it, and a smart charger helps you do exactly that.
Smart charging and battery storage
If you also have a battery, a smart charger becomes part of a wider energy system.
Together, they can:
- Store energy during the day
- Charge your car overnight on cheaper tariffs
- Reduce reliance on the grid during peak times
It’s a more joined-up approach to energy, one that improves overall efficiency and long-term savings.
What about cost?
Smart chargers do typically cost more upfront than standard chargers.
However, over time they can:
- Reduce electricity bills
- Increase use of free solar energy
- Adapt to changing energy tariffs
In many cases, the long-term savings outweigh the initial difference, particularly for homes with solar panels.
A quick note on 3-pin charging
Some EVs come with a 3-pin “granny charger” that plugs into a standard socket.
These can be useful occasionally, but they are:
- Very slow (often taking over 24 hours for a full charge)
- Not designed for regular, long-term use
- Potentially risky if used on older wiring or for extended periods
For most EV owners, a dedicated home charger is the safer and more practical solution.
Which charger is right for you?
A standard charger may suit you if:
- You don’t have solar (and don’t plan to)
- You’re looking for the lowest upfront cost
- You have simple charging needs
A smart charger is usually the better choice if:
- You have (or are planning) solar panels
- You want to reduce energy costs
- You want more control and flexibility
- You’re thinking long-term
Looking ahead: bi-directional charging
One of the most exciting developments in EV charging is bi-directional charging.
This allows your car battery to do more than just charge, it can also:
- Power your home
- Store excess solar energy
- Support the grid when needed
SolarEdge already has a bi-directional charger ready to launch, currently awaiting final regulatory approval for grid integration.
At Sunlit Solar, we’re preparing for this next step and will be ready to install these systems as soon as they are approved, so watch this space!
The bottom line
Both standard and smart chargers will charge your car.
But a smart charger does more than that. It helps you:
- Use more of your own energy
- Reduce reliance on the grid
- Lower your long-term running costs
When combined with solar and battery storage, it becomes part of a much smarter, more efficient home energy system.
