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
No utility lines? That's not a problem. That's the point.
Rural homesteads, hunting cabins, lake houses, farms and ranches. Some properties are miles from the nearest power line. Running one out can cost $15,000 to $50,000 or more. Others simply prefer not to depend on a utility.
Off-grid solar replaces the grid entirely. Your panels, your batteries, your power plant.

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
Inverters
EG4 6000XP and 12000XP inverter/chargers. Split-phase 120/240V output for full-size appliances, well pumps and HVAC.
- ✓ 6,000W or 12,000W continuous
- ✓ Stackable for larger systems
- ✓ Built-in MPPT charge controller
Batteries
Three LiFePO4 options with 10-year warranties. Sized to your capacity needs and environment.
- ✓ WallMount 314Ah: 16 kWh, 10,000+ cycles
- ✓ PowerPro 280Ah: IP65, self-heating
- ✓ LifePower4 v2: stackable rack units
Solar Panels
440W Tier 1 panels with 21%+ efficiency. Ground or roof mount. See our solar panels page for full specs.
- ✓ Hail rated for Oklahoma weather
- ✓ 25-year manufacturer warranty
- ✓ Sized for lowest-production months
Generator Integration
For extended cloudy periods or heavy seasonal loads, we integrate a backup generator. The inverter auto-starts it when battery levels drop and stops it once batteries are charged.
- ✓ Auto-start and auto-stop
- ✓ Charges batteries while powering loads
- ✓ Propane or diesel options
System Design
How we size your system
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.
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.
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.
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) |
| 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
sunny days per year
Oklahoma averages over 3,090 sunshine hours annually. That is 15% above the national average and one of the best solar resources in the country.
Storm-ready by design
Off-grid means no backup grid. We design for that reality. Hail-rated panels, outdoor-rated batteries with self-heating for winter and generator integration for extended cloudy periods.
EG4 batteries operate from -4°F to 131°F. The PowerPro model heats itself automatically through Oklahoma winters. No external equipment needed.
