Off-Grid Power Systems
Quick answer
True off-grid and grid-optional power, solar arrays sized for winter, serious battery banks, and generator backup for the dark weeks. Engineered systems, not kits.Off-grid is an engineering discipline: the system must survive its worst week, not average its best month. We design around winter solar production, real load budgets, battery depth for cloudy stretches, and a generator for the residual, for cabins, homesteads, and remote properties beyond the utility's reach.
About Off-Grid Power Systems
Off-grid design starts from a number most people have never calculated: the daily kilowatt-hours you're committing to live on. Everything cascades from it, array size against December sun, battery bank against cloudy stretches, generator runtime against the residual. Honest systems begin with honest load budgets.
We build the whole stack: solar arrays mounted and angled for winter production, LiFePO4 battery banks sized for 2–3 days' autonomy, inverter/charger systems with generator integration, and the load-side discipline (propane for heat and cooking, efficient pumps) that keeps the numbers rational.
The off-grid design sequence
- Load budget: every circuit, every season, in kWh/day
- Solar sized to worst-month production, not annual average
- Battery: 2–3 days autonomy at realistic depth of discharge
- Generator for the residual, the economical last 5%
- Monitoring so you see trouble a week before it's cold showers

Modest cabins start around $15,000–$25,000; full-home off-grid with winter-capable arrays and generator backup typically runs $40,000–$80,000+. The load budget you commit to drives everything.
Yes, grid-optional (solar + substantial battery + islanding) keeps utility convenience while surviving indefinite outages. It's the right call for most homes; true off-grid is for where the grid isn't.
Honestly: a generator. Sizing batteries for the worst week of the year is uneconomic; a propane generator covering the residual 5% keeps the battery bank rational.
Yes, with design and budget, modern LiFePO4 banks and cheap panels changed the math. What still doesn't pencil is electric resistance heating off-grid; propane or wood carries the heat load in serious climates.
