Electrical Panel Upgrades for EV Infrastructure
Future-proof your home or business with a code-compliant electrical panel upgrade. We size, permit, and install upgrades that fully support Tesla Powerwall, Wall Connectors, and EV charging — all across the Tampa Bay area.
How Your Panel Upgrade Works
From initial assessment to final inspection, Gulfstar Electric handles every step of your electrical panel upgrade — so you get a safe, permitted, EV-ready electrical system without the guesswork.
Electrical Assessment
Our licensed electricians perform a thorough on-site evaluation of your existing panel, service entrance, load profile, and wiring. We identify any code deficiencies and determine the exact upgrade path needed to support EV charging, Powerwall, or other high-demand loads.
Panel Sizing & Design
We calculate your current and future electrical loads — including EV chargers, battery storage, HVAC, and appliances — to specify the correct panel amperage (100A, 200A, 400A, or sub-panel). Our team designs a system that gives you room to grow without costly future rewiring.
Upgrade Installation
Our certified electricians safely replace or upgrade your electrical panel with a new code-compliant unit. We coordinate the utility company disconnect, perform the swap with minimal downtime, run new circuits as needed, and ensure every breaker is properly labeled and bonded.
Permitting & Inspection
Gulfstar Electric pulls all required permits with your local municipality or county — including Hillsborough, Pinellas, Manatee, and Pasco counties. We schedule and pass the electrical inspection so your installation is fully documented, code-compliant, and insurable.
EV Infrastructure Commissioning
Once the panel upgrade is approved, we install your EV charging circuit, Tesla Wall Connector mount point, or Powerwall connection. We test every load, verify breaker ratings, and hand you a complete documentation package — ready for manufacturer warranties and future service.

Use this reference guide to understand amperage requirements, EV charger and battery compatibility, and typical Tampa Bay upgrade costs before your free assessment.
Panel Amperage
Basic upgrade — suitable for smaller homes with single EV charger (Level 2, up to 30A circuit)
Standard residential upgrade — supports Level 2 EV charging + Powerwall + full home loads
Heavy-duty residential or light commercial — supports dual EV chargers, Powerwall 3, full HVAC, pool equipment
Adds dedicated circuits for EV/battery loads without replacing main panel — cost-effective in many cases
EV Charger Compatibility
Requires dedicated 60A / 240V circuit — 200A+ panel recommended for whole-home compatibility
Standard 40–50A / 240V dedicated circuit — compatible with all panel sizes after upgrade
Requires dedicated 3-phase or 200A+ service — commercial panel upgrade or utility upgrade required
Battery & Storage Compatibility
11.5 kW continuous output — requires 200A panel minimum, dedicated Gateway connection
7.6 kW / 5 kW output — 200A panel recommended; load-managed 150A installations possible
Microinverter-based — compatible with existing 200A service; minimal panel impact
Full backup requires transfer switch + 200A+ service — Gulfstar Electric configures both simultaneously
Typical Upgrade Costs (Tampa Bay)
Approximately $1,800 – $3,500 depending on meter location, wiring distance, and permit fees
Approximately $2,500 – $4,500 — includes EV-ready sub-panel wiring run
Approximately $3,500 – $6,000 — often requires utility coordination and new meter base
Approximately $800 – $2,000 — ideal when main panel has capacity headroom
Permitting & Code
All panel upgrades must meet NEC 2020 as adopted by Florida — Gulfstar ensures full compliance
Hillsborough, Pinellas, Manatee, Pasco, and Polk counties all require permits for service upgrades
TECO, Duke Energy, and FPL coordination included — we schedule and manage utility hold periods
NEC 2020 requires AFCI/GFCI on specified circuits — included in all Gulfstar panel upgrade scopes
