Frequently Asked Questions

Common questions about off-grid power systems in Havre

Answers about solar sizing, battery storage, generator backup, and system costs for northern plains bunkers.

Without power, air filtration stops within minutes, leaving your family breathing stale air with rising CO2 levels. Lighting, heating, and communication systems shut down. Battery banks that aren't sized for 3-5 days of storage run out during cloudy periods, forcing you to surface during a crisis. Proper solar array sizing and generator backup prevent this failure.

Systems range from $15,000 for basic 5kW solar with 48V battery bank to $40,000+ for 10kW arrays with generator backup and load balancing. Cost depends on bunker size, power load from air filtration and heating systems, and battery storage days needed. We provide detailed quotes after load calculation and site assessment.

We calculate arrays at 150% of summer load to account for 40-50% winter production loss from low sun angles, shorter days, and snow cover. Panels are tilted at 60 degrees to shed snow and capture winter sun. Battery banks store 3-5 days of power for cloudy stretches when solar output drops near zero.

Yes, electrical permits are required for solar panel installation, battery bank wiring, and generator integration. We handle permit applications and inspections to ensure systems meet Montana electrical code and local building requirements for off-grid installations.

The 33% rule suggests solar arrays should produce 33% more power than daily consumption to account for inefficiencies and cloudy days. For Havre bunkers, we size arrays at 150% of load because winter production drops 40-50% and battery recharge must happen during short daylight hours while systems run simultaneously.

Lithium iron phosphate batteries last 10-15 years with proper charge controller management. Lead-acid batteries degrade faster, lasting 5-7 years. Without charge controllers preventing overcharge and deep discharge, batteries fail within 2-3 years. We install charge controllers and test battery health annually to prevent unexpected failure.

Yes, when properly sized. CBRN air filtration draws 500-800W continuously, electric heating adds 1,500-3,000W depending on bunker size. We calculate total load including lighting and communication systems, then size solar arrays and battery banks to handle peak demand for 3-5 days without sun.

Generator backup with auto transfer switch provides redundant power when solar production fails. We install panels in protected locations when possible and include spare panels in larger systems. EMP-shielded wiring protects charge controllers and inverters from electromagnetic pulse damage that would disable the entire system.
