⚡ EV Charger Installation: What You Need to Know Before You Buy
As California leads the charge toward electric vehicles, more and more homeowners in areas like Agoura Hills, Simi Valley, Calabasas, Westlake Village, and across Ventura and Los Angeles Counties are buying EVs and realizing — sooner or later — they need a dedicated EV charger at home.
But installing a charger isn’t as simple as plugging in a cord. There’s a lot to consider before you buy or install your first EV charging system. From understanding your home’s electrical capacity, to knowing if you need a panel upgrade, this guide will help you make an informed decision that’s safe, cost-effective, and future-proof.
At DNZ Electrical Services, we’ve helped hundreds of Southern California homeowners prepare their homes for Tesla, Ford Lightning, Rivian, and all other EV models. Here’s everything you need to know.
🚗 Why Install an EV Charger at Home?
Sure, you can charge your EV at public stations — but that’s not ideal for long-term convenience, cost, or control. Here’s why homeowners are choosing to install their own EV charging stations at home:
✅ Convenience:
Charge your vehicle overnight while you sleep. No waiting in line, no searching for a charging station.
✅ Faster Charging:
Level 2 chargers (240V) can fully charge most EVs in 4–6 hours, compared to 24–36 hours on a standard Level 1 plug.
✅ Lower Energy Costs:
Home EV chargers can be set to run during off-peak hours, which saves money on your electric bill.
✅ Increased Property Value:
A home equipped with a modern EV charger is more attractive to future buyers.
🔌 EV Charger Types: Level 1 vs. Level 2
Before you buy an EV charger, it’s important to understand your options. There are two common types of EV chargers:
🔹 Level 1 Charger
-
Uses a standard 120V household outlet (like what your microwave uses)
-
No special installation needed
-
Adds 3–5 miles of range per hour (very slow)
-
Best for plug-in hybrids or occasional use
🔹 Level 2 Charger
-
Requires a 240V circuit (like a dryer or oven plug)
-
Needs professional installation
-
Adds 25–50+ miles of range per hour
-
Ideal for Tesla, Rivian, Ford Mustang Mach-E, and other full EVs
-
Most common for residential installations
DNZ Electrical Services installs all Level 2 chargers, including Tesla Wall Connector, JuiceBox, ChargePoint, Wallbox, and more.
🧰 Do You Need a Panel Upgrade for an EV Charger?
This is one of the most important questions — and one most homeowners don’t consider until it’s too late.
In many cases, yes — you may need an electrical panel upgrade.
Most older homes in Agoura Hills, Simi Valley, or Thousand Oaks were built with 100 amp electrical panels, which can be insufficient to safely support a Level 2 EV charger, especially if you also use high-powered appliances like HVAC systems, electric ovens, pool pumps, or electric dryers.
💥 Risks of Not Upgrading:
-
Overloaded circuits
-
Frequent breaker trips
-
Potential fire hazards
-
Insurance violations
-
EV charger underperformance
At DNZ, we often recommend a 200 amp panel upgrade to support the charger and future-proof your home for solar, batteries, or additional EVs.
