Southern Utah spec
EG4 whole-home backup
EG4 PowerPro wall-mount or LifePower4 rack systems paired with the EG4 18kPV hybrid inverter. Typical St. George build: 15–30 kWh for backup, 45–90 kWh for full off-grid homes.
Serving St. George · Washington County · Arizona Strip
Off-grid solar & EG4 battery installer in St. George, Utah.
Southern Utah has the best solar resource in the country and some of the most remote building sites. That combination is our specialty. EnergBase has designed and built 50+ off-grid homes across the region — whole-home EG4 LiFePO₄ battery systems, hybrid inverters, geothermal heat pumps, and Grundfos solar water wells, all wrapped in 24/7 AI monitoring via Solar Assistant.

50+Off-grid homes
24 / 7AI oversight
Why Southern Utah off-grid is different.
St. George sits at 2,860 ft with ~300 sunny days a year and summer cooling loads that punish undersized systems. Hurricane and LaVerkin have the same resource, with building lots that often sit 1,000+ ft from the nearest power line. Most installers don't design for that. We do.
Dixie solar advantage
High-yield solar array
Washington County's DNI hits 6.5+ kWh/m²/day — the highest in the state. That usually means a smaller array does the same work as elsewhere. We model the exact sizing for your roof or ground mount.
Rural builds
Off-grid solar wells
For remote lots outside Hurricane, LaVerkin, Virgin, and Rockville, pulling power to a well is often more expensive than a Grundfos solar-direct pump. We've run 280 GPM wells this way — no batteries, no inverters.
Cooling-dominated loads
Geothermal heat pumps
St. George summers are brutal on any off-grid AC load. Geothermal cuts that load so hard it usually pays for itself in saved solar and battery capacity. Fewer than 1% of US homes run them. For off-grid dream homes, it's the right call.
EnergBase Agent · Always on
Remote monitoring, watched from the Arizona Strip to Cedar City.
Every EnergBase system we install in Southern Utah ships with Solar Assistant pre-configured and our AI agent watching every cell 24/7 — so our team in Hurricane catches drift on your cabin in Pine Valley before you notice a flicker.
Live dashboards
Per-cell voltage, temperature, and SoC from your phone in Vegas, St. George, or anywhere you're not at the cabin.
Weeks of warning
Our models flag imbalance and capacity fade long before a cell hits its limit — the right battery gets swapped before the system ever faults.
Utah-tuned optimization
Adaptive SoC windows tuned to Rocky Mountain Power plans for grid-tied systems, or to your own load profile for off-grid builds.
A real human to call
Based in Hurricane. We pick up. Always.
