    Start Your Custom Build

Silence the Generator. Reclaim Your Independence.

You didn't invest in a luxury rig to listen to a rattling generator or worry about dead batteries at midnight. At Xtreme Off Grid, we replace outdated lead-acid anxiety with military-grade, high-capacity Lithium (LiFePO4) micro-grids. Run your A/C, make your espresso, and stay off-grid indefinitely.

Aerospace-Grade Craftsmanship

Engineered by a former USAF AWACS technician and Senior DevOps Engineer. We don't just run wires; we build highly redundant, code-compliant power architectures.

100% Mobile Execution

We bring the custom shop to you. Fully compliant with Designated Point of Installation (DPOI) standards at your residence, RV park, or marina. No contractor's license is required for our mobile installations.

Victron Energy Certified

Authorized professionals utilizing the global gold standard in mobile power components. Built for the extreme, guaranteed to perform.

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).

Uncompromising Standards

Please Note: Xtreme Off Grid strictly engineers and installs premium LiFePO4 Lithium systems. To maintain our standard of safety and performance, we absolutely do not sell, install, or service legacy Lead-Acid, AGM, or Gel batteries.


All complete integrations are backed by a 1-year craftsmanship guarantee on physical installation and initial baseline programming.
