Off-Grid Solar for Oklahoma

Complete energy independence. No utility bill. No grid connection. Solar panels, battery storage and inverters designed for properties beyond the power lines.

Who It's For

Built for properties off the beaten path

Rural Homes

Properties where running utility lines would cost tens of thousands of dollars. Off-grid solar pays for itself faster than a grid connection in many rural Oklahoma locations.

Cabins and Retreats

Weekend getaways, hunting cabins and lake properties. Systems sized to match your usage patterns, whether you're there full-time or just on weekends.

Farms and Ranches

Power for barns, workshops, irrigation pumps and outbuildings. Off-grid solar eliminates the cost of running lines across large properties.

Our Equipment

Powered by EG4

We build our off-grid systems around EG4 Electronics. Their inverters and batteries are purpose-built for off-grid applications. Not adapted from grid-tied products. Designed from the ground up for standalone power.

Every battery in the lineup uses LiFePO4 chemistry at 48V/51.2V. That means longer cycle life, better performance in extreme temperatures and no thermal runaway risk. The self-heating feature on the PowerPro 280Ah keeps the batteries operational through Oklahoma winters without external heating equipment. See our battery storage page for the full lineup including Tesla Powerwall and FranklinWH options.

EG4 delivers the lowest cost per kilowatt-hour of any battery brand we install. For off-grid builds where you need serious storage capacity, that cost difference adds up fast.

Components

What goes into your system

EG4 off-grid inverter/charger

Inverters

EG4 6000XP and 12000XP inverter/chargers handle the conversion from DC solar and battery power to AC for your home. They support split-phase 120/240V output for full-size appliances, well pumps and HVAC systems.

  • 6000XP: 6,000W continuous, ideal for cabins and smaller homes
  • 12000XP: 12,000W continuous, full-size homes and heavy loads
  • Stackable for larger systems
  • Built-in MPPT solar charge controller
EG4 WallMount LiFePO4 battery

Batteries

Three battery options depending on your capacity needs and installation environment. All use LiFePO4 chemistry with 10-year warranties.

  • WallMount 314Ah: 16 kWh, 10,000+ cycles, indoor or outdoor
  • PowerPro 280Ah: 14.3 kWh, IP65 outdoor rated, self-heating
  • LifePower4 v2: 5.12 kWh rack units, stackable up to 64 units
Tier 1 monocrystalline solar panel

Solar Panels

440W Tier 1 panels with 21%+ efficiency. Sized to match your daily energy consumption plus a buffer for cloudy days and seasonal variation. See our solar panels page for full specs.

  • Ground mount or roof mount options
  • Hail rated for Oklahoma weather
  • 25-year manufacturer warranty

Generator Integration

For extended cloudy periods or heavy seasonal loads, we can integrate a backup generator into your off-grid system. The inverter starts the generator automatically when battery levels drop and stops it when batteries are charged.

  • Auto-start and auto-stop
  • Charges batteries while powering loads
  • Propane or diesel options

System Design

How we size your system

1

Energy audit

We start with your actual energy needs. Every appliance, every light, every well pump. Off-grid systems have no utility to fall back on, so accurate load calculation is critical.

2

Solar production modeling

We model solar production for your specific location using Oklahoma weather data. The system is sized for your lowest-production months, not your best. That way you have enough power year-round.

3

Battery bank sizing

We calculate how many days of autonomy you need. Most systems are designed for 2 to 3 days of cloudy weather without generator backup. More if you want to run purely on solar.

4

Install and commission

Our crew handles everything: panel mounting, battery installation, inverter wiring, generator integration and system commissioning. We test every circuit before we leave.

Comparison

Off-grid vs grid-tied

Feature Off-Grid Grid-Tied
Utility bill None Reduced (net metering credits)
Battery required Yes (mandatory) Optional (for backup)
Grid outage impact No impact Loses power (unless battery backup)
System size Larger (must cover 100% of load) Can be smaller (grid supplements)
Upfront cost Higher Lower
Monthly cost $0 Reduced utility bill
Best for Rural, no grid access, full independence Urban/suburban, reduce utility costs

Oklahoma Specific

Built for Oklahoma conditions

235 sunny days per year

Oklahoma averages about 3,090 sunshine hours per year. That is well above the national average and makes the state one of the better locations in the country for solar energy production.

Storm-ready design

Our systems are designed for Oklahoma weather. Hail-rated panels, outdoor-rated batteries with self-heating for winter and generator integration for extended cloudy periods during storm season.

No utility required

Running utility lines to a rural Oklahoma property can cost $15,000 to $50,000 or more depending on distance. An off-grid solar system often costs less than the grid connection itself and eliminates the monthly bill permanently.

Common Questions

Off-grid FAQ

How much does an off-grid solar system cost in Oklahoma? +
Costs vary based on energy needs, battery capacity and system size. A small cabin system starts lower than a full-size home system. In many rural locations, the off-grid system costs less than running utility lines to the property. Contact us for a free site assessment and custom quote.
Can I run AC, a well pump and a dryer on off-grid solar? +
Yes. The EG4 12000XP inverter delivers 12,000W continuous with split-phase 240V output. That is enough to run central AC, well pumps, electric dryers and other large appliances. We size the battery bank to handle your peak loads and daily consumption.
What happens during a week of cloudy weather? +
We size systems for 2 to 3 days of autonomy without sun. Solar panels still produce 10 to 25% of their rated output on overcast days. For extended cloudy periods, we recommend generator integration. The EG4 inverter will auto-start the generator when battery levels drop and stop it once batteries are charged.
Do I need permits for off-grid solar in Oklahoma? +
Permitting requirements vary by county. Some rural Oklahoma counties have minimal requirements for off-grid installations. We handle all permitting and inspections as part of the installation. No extra work on your end.
How long do the batteries last? +
EG4 LiFePO4 batteries are rated for 8,000 to 10,000+ cycles depending on the model. With daily cycling, that is over 20 years of service life. All batteries include a 10-year manufacturer warranty.
