Our Process: Engineered for Your Convenience
The 3-Step Build Process

Phase 1: Consultation & System Architecture
Every successful build starts with a blueprint. We begin with a comprehensive consultation to assess your exact power needs, your rig's layout, and your travel style. From there, we engineer a custom system architecture and provide a detailed, transparent quote.
Phase 2: Equipment Procurement
To ensure we are installing only the highest-tier, factory-fresh components, equipment is procured specifically for your build. 100% of the hardware cost is collected upfront to lock in your components, secure your installation dates, and initiate shipping.
Phase 3: Mobile Execution & Commissioning
We arrive at your location to execute the build. Labor is billed on a standard 50/50 split (50% due at project start to retain your dedicated installer, and the final 50% due only when the system is successfully commissioned, tested, and handed over to you).
Where We Work
Standard Service
We are fully equipped to perform your installation at your residence, storage facility, RV resort, or marina. To ensure a smooth and safe installation process, we simply ask that your chosen location has adequate space for our service vehicles and safe clearance to work on roofs and battery bays.
Note: If we are working at a commercial RV park or marina, please ensure you have secured any necessary management approvals or gate codes prior to our arrival!
Our Coverage Zone
Our standard service area covers a 100-mile radius around our home base in Corona/Temescal Valley, spanning from West LA to Lake Havasu, and Victorville to San Diego. Outside the zone? We frequently accommodate extended travel and air-travel installations for specialized projects. Custom logistical quotes are available upon request.


The Lithium Standard
We engineer high-tier, reliable micro-grids. To maintain our uncompromising standard of safety and performance, Xtreme Off Grid specializes exclusively in Lithium Iron Phosphate (LiFePO4) battery architectures. We do not service, sell, or install outdated lead-acid, AGM, or Gel battery banks.
