Get My Estimate ↓Panel size, existing breakers, meter disconnect, roof entry — the real factors that drive your cost.
See exactly what you're paying for — panel, breakers, detectors, GFCI compliance — with a realistic range.
When you're ready to move forward, reach out. We'll schedule a site visit and lock in your exact number.
Count all breakers in the panel including doubles. Not sure? 20 is typical for a 3-bedroom home. Each gets replaced with a new AFCI/GFCI breaker.
A meter disconnect lets the power be shut off without calling the utility. Required by many local inspectors. If unsure, select No.
Look for conduit or wires coming through the roof into a weatherhead. Roof entries add labor for flashing and sealing.
GFCI outlets (with TEST/RESET buttons) are required in kitchens, bathrooms, garage, and exterior. Older homes often need these added to pass inspection.
Georgia code requires hardwired, interconnected detectors. Battery-only units don't meet this requirement and will be flagged at inspection.
One smoke-only detector per bedroom. Two combo smoke/CO units added for the hallway and main level.
CO detectors are required near sleeping areas when gas appliances or an attached garage are present.
One combo smoke/CO detector per location.
Estimates are for budgeting purposes only and do not constitute a proposal or contract. Final pricing depends on field conditions, utility requirements, and AHJ inspection standards. Permit fee not included. GE Martin Electrical LLC — Licensed Electrical Contractor, Georgia License #EN218401.
INSTALLATION
Getting an electric vehicle? See what a Level 2 home charger installation costs before you buy.
Calculate EV Charger Cost ↓Most EVs charge fully overnight on a 50A circuit. Check your vehicle's onboard charger rating — that's your ceiling.
Longer runs require more wire and conduit. Measure roughly from your panel to the garage or driveway where the charger will mount.
Detached garages and outdoor installs require weatherproof conduit and may need trenching.
If your panel is full or close to its limit, a subpanel or load management device may be needed. Not sure? Select No and we'll include an allowance.
Trenching is required when running underground between buildings or across a driveway. Wall penetrations are typical for most installs.
We supply and install hardwired Level 2 chargers (NEMA 14-50 or hardwired). Popular brands: ChargePoint, Enel X JuiceBox, Grizzl-E.
Estimates are for budgeting purposes only. Hardware pricing varies by brand and model. Permit fee not included. GE Martin Electrical LLC — License #EN218401.
BACKUP POWER
Outages happen. See what a standby generator, a home battery system, or a hookup for the portable generator or battery you already own costs to install.
Calculate Backup Power Cost ↓Not sure? 22 kW covers most 2,000–3,500 sq ft homes with one or two A/C units. We size it properly at the site visit.
Natural gas is the most common choice if your home already has gas service. Propane works anywhere and needs a tank on site.
If the gas line has to be extended, a licensed gas fitter runs it. We include an allowance. Not sure? Select No.
Essential circuits keeps the fridge, lights, furnace and key outlets running through a backup load center. Whole home uses a service-rated transfer switch.
Typical essentials run 8–12 circuits: fridge, lights, furnace or A/C, garage door, Wi-Fi, and a few outlets.
Generators must sit a minimum distance from windows and openings. Longer runs need more wire and conduit.
Runtime depends on what you power. Heavy loads like A/C and electric heat drain a battery fast, so we size around the circuits you choose.
We can supply and install your system, or install one you already own. Hardware pricing varies by brand and model.
The selected circuits move to a new critical-loads subpanel that the battery powers during an outage.
Outdoor installs need weatherproof mounting and conduit.
Longer runs require more wire and conduit.
A manual transfer switch moves the circuits you choose onto backup power. It is the simplest, most controlled setup. An interlock lets you power any circuit in your existing panel, but you manage the load yourself.
Typical essentials run 8–12 circuits: fridge, lights, furnace, garage door, Wi-Fi, and a few outlets. They move to a new load center behind the transfer switch.
An interlock mounts on the panel's main breaker. If your panel has no main (main-lug only), we add a main disconnect first. Not sure? Select No and we'll include an allowance.
Portable generators must run outdoors, so their inlet mounts on an exterior wall with a line run to the panel. A battery kept in a garage or utility room can plug into an inlet right next to the panel. Need both? Call us. We wire it so both inlets can never be live at once.
Longer runs require more wire and conduit.
Check the outlet on your generator or battery. 30A fits most portable generators. 50A is for larger units. Not sure? Choose 30A and we'll confirm at the site visit.
Estimates are for budgeting purposes only and do not constitute a proposal or contract. Equipment pricing varies by brand and model. Gas line and propane figures are allowances; final cost depends on site conditions. Utility interconnection or application fees, if required, are not included.

Already own one of these, or thinking about it? Here is how the common portable battery systems line up for a home hookup.
| Unit | Capacity | Max output | 240V? | Home hookup notes |
|---|---|---|---|---|
| Anker SOLIX F3800 Plus | 3.84 kWhexpandable to ~27 kWh | 6,000 W | Yes — L14-30R outlet | Strong fit for a 30A inlet. Can also take a 240V generator input to recharge in a long outage. |
| EcoFlow DELTA Pro Ultra | 6 kWh per batteryexpandable to 90 kWh | 7,200 W per inverter | Yes — 120/240V | Built for whole-home use. Pairs with EcoFlow's Smart Home Panel for automatic switchover. |
| EcoFlow DELTA Pro 3 | 4.1 kWhexpandable with extra batteries | 4,000 W8,000 W surge | Yes — L14-30R outlet | Switches between a 120V inverter and a 120/240V inverter, and only one runs at a time. 30A inlet. |
| Bluetti Apex 300 | 2.8 kWhexpandable | 3,840 W | Yes | 240V outlets are meant for a transfer switch. Confirm the outlet type before we size the inlet. |
| Bluetti Elite 400 | 3.84 kWhnot expandable | 2,600 W | No — 120V only | Can only power 120V circuits. Not a match for a 240V inlet or whole-panel interlock. |
Not on the list? Many similar units work. Call us with the model and we'll confirm the inlet and breaker size. Specs come from manufacturer and retailer listings and change by model and firmware, so check your unit's manual before you buy. Want automatic switchover instead? EcoFlow and Anker both sell smart panel systems that transfer on their own. That is the Battery option in the calculator above.
