EV Charger Site Assessment — What We Check and Why

Before any charger goes on any wall, there’s one step that determines whether your installation goes smoothly or becomes a headache: the EV charger site assessment. It’s a short visit where a trained assessor examines your home’s electrical system and your parking setup, then tells you exactly what your installation will involve — and cost. At MOEV Solutions, this assessment is completely free, and honestly, it’s the step we’d never let a client skip even if they wanted to.

Here’s exactly what we look at during an assessment, why each item matters, and what goes wrong when installers skip it.

What We Check During a Site Assessment

1. Electrical Panel Capacity

Your panel is the heart of the whole project. A 7kW charger adds a significant continuous load — around 32A on a single-phase supply — and your panel either has room for that or it doesn’t. We evaluate your panel’s rating against your existing household load: aircon units, water heater, kitchen appliances, everything.

If there’s comfortable headroom, great — standard installation. If the panel is near its limit, we’ll tell you upfront that a panel upgrade or load management is needed, and quote it clearly. What we won’t do is bolt a charger onto an overloaded panel and hope for the best. That’s how breakers nuisance-trip at 2am — or worse.

2. Spare Breaker Slots

The Philippine Electrical Code requires your charger to run on its own dedicated circuit with its own breaker — no sharing with the aircon, no tapping off an existing outlet circuit. That means your panel needs a physical slot for a new breaker (plus RCD protection). Full panels are common in older homes; the fix might be a small sub-panel, and it’s much better to know that at the quoting stage.

3. Distance From Panel to Parking

We physically walk and measure the cable route from your panel to where the charger will hang. This single measurement drives a big chunk of installation cost: more distance means more cable, more conduit, more labor, and on long runs, a heavier wire gauge to keep voltage drop in check.

This is also where we figure out the route itself — along a wall, overhead, underground across a driveway? Each option has different material and labor implications. Guessing this over the phone is how hidden costs get baked into your project.

4. Wall and Mounting Surface

Not every wall is charger-ready. We check that your intended mounting spot is structurally solid (concrete and solid block are ideal), at a workable height, protected from vehicle bumps, and — if outdoors — assess what weatherproofing the location needs. If your preferred spot isn’t suitable, we’ll suggest alternatives on the spot. There’s a bit of an art to this; we wrote more about it in where to mount your EV wall charger.

5. Earthing (Grounding)

This one is invisible to homeowners but critical to safety. Proper earthing is what makes RCD protection meaningful — it’s the path that lets fault current trip the breaker instead of passing through a person. Many older Philippine homes have weak or degraded earthing, and some have practically none. We check it, and if it needs improvement, that goes into the quote. A charger without proper earthing isn’t a charger; it’s a hazard with an app.

6. Your Load Profile and Charging Habits

Finally, we talk to you. When do you usually get home? Does the whole household run aircon all night? Do you plan to charge daily or a few times a week? Your answers shape recommendations — like whether a smart charger with scheduling makes sense, or whether your panel headroom is fine because charging happens when other loads are low. Electricity at around around ₱15/kWh overnight at home already beats public charging at ₱20–₱38/kWh; a bit of planning makes it even more sulit.

What Happens When You Skip the Assessment

We’ve seen the aftermath of skipped assessments, and it follows a pattern:

• The mid-job price jump. Installer quotes low sight unseen, discovers the 35-meter cable run on installation day, and suddenly there are “additional charges.” Now you’re negotiating with a half-finished install on your wall.
• The overloaded panel. Charger works fine — until summer, when the aircon load peaks and breakers start tripping nightly.
• The unsafe shortcut. No slot for a new breaker? Some installers just tap an existing circuit. It powers the charger, sure. It also violates the PEC and creates a genuine fire risk under continuous load.
• The wrong-location regret. Charger mounted where the cable barely reaches the charge port, so every session starts with awkward car repositioning. Forever.

Every one of these is preventable with a one-visit assessment. ‘Yung thirty minutes of checking saves you years of problems.

What You Need to Prepare (Almost Nothing)

For the visit itself: access to your electrical panel, access to your parking area, and about 30–60 minutes. If you already own your charger unit (say, the wall charger from your car dealer), have it or its spec sheet handy. That’s it. The assessment feeds directly into your written quote — standard installs run quoted after a free site assessment for labor and standard materials, and anything beyond standard gets itemized clearly. It’s the first step of the full installation process.

Frequently Asked Questions

Is the site assessment really free?

Yes — free, and with no obligation to proceed. We’d rather assess a hundred homes for free than install one charger on a site we haven’t seen.

How long does an assessment take?

Typically 30–60 minutes, depending on the complexity of your site. Condo assessments can take a bit longer if building admin coordination is involved.

Can you assess from photos instead of visiting?

Photos help us prepare, and for simple questions they’re a great start. But panel capacity, earthing, and accurate cable measurement need eyes and instruments on site. We won’t issue a final quote from photos alone.

What if the assessment finds problems with my electrical system?

Then you’ve just learned something important about your home for free. We’ll explain the issue plainly, present options, and quote the fix. You decide — no pressure, no scare tactics.
