From Factory Floor to Charging Site: How eM4’s Customization Delivers Faster Deployment

3 min read

In commercial EV charging, speed to market is everything. Whether you’re deploying a hotel charging network, scaling fleet infrastructure, or rolling out public charging points, every extra day between delivery and go-live costs you – in time, resources, and potential revenue.

That’s why the Wallbox eM4 isn’t just designed for performance at the plug. It’s built for efficiency from the moment it leaves our factory. With eM4’s Customization & Pre-Configuration Service, we help operators go from delivery to operation faster, with fewer on-site errors and less back and forth between teams.

The Real-World Challenge: Commissioning Delays

In an ideal world, commissioning a commercial EV charger is straightforward. All the information is ready. The installer knows the setup. Everything works the first time.

In reality?

The installer could arrive without the correct data to connect to the OCPP backend.
SIM cards aren’t configured, or worse, they arrive late.
The customer isn’t clear on technical requirements.
A sub-contracted electrician is unfamiliar with EV charger connectivity.

Each of these scenarios can delay commissioning by days, requiring repeat site visits and additional costs. And when you’re scaling across multiple locations, those delays multiply fast.

How eM4’s Customization Solves This

Our advanced, flexible production line allows us to pre-configure and customize your eM4 units before they even leave our factory. That means when they arrive on-site, they’re ready to go – no missing steps, no unnecessary delays.

Here’s what we can do for you:

Factory OCPP Provisioning
We set all necessary OCPP parameters in advance – including URLs, charger IDs, and authentication settings – so your units connect immediately on-site.
SIM Card Installation & Testing
Send us your SIM cards before shipping. We’ll insert them, configure APNs, and test connectivity during our End-of-Line checks, ensuring your charger connects instantly when powered up.
Custom Bill of Materials
Need QR codes, branded instruction sheets, or location-specific stickers? We’ll include them inside the box so they’re ready for installation.
Premium Branding Behind the Glass
Your logo is printed behind impact-resistant glass for a sleek, professional finish that won’t fade or peel, keeping your chargers on-brand for years to come.

The Benefits: Speed & Standout Branding

Two things matter most when deploying commercial charging at scale: commissioning speed and brand impact.

With eM4 Customization, you get both:

→ Faster, Error-Free Commissioning: Minimise on-site configuration and eliminate common errors, reducing deployment timelines from days to hours.

→ Brand Presence That Lasts: Deliver a premium charging experience that reflects your brand’s quality, from first impressions to long-term use.
