About Us

Power Where Pavement Ends

Veteran-Owned. Arizona-Based. Built for the Off-Grid Life.

4xSolar is an online store built for people who go where the grid doesn't. Whether you're overlanding through the desert, building a DIY solar setup for your cabin, or putting together an emergency power system for your family — we're here to get you the right gear at a fair price.

Who We Are

4xSolar was founded in 2026 by Carlos Diaz, a retired U.S. Air Force pilot based in Tucson, Arizona. After years of relying on equipment in situations where failure wasn't an option, Carlos built 4xSolar with the same standard: every product has to work when it matters.

That military mindset drives everything we do — from the suppliers we choose to the gear we recommend. We don't carry products we wouldn't trust in our own rig.

What We Sell

  • LiFePO4 Battery Systems — EVE cells, pre-built packs, BMS units, and all the components to build your own off-grid power bank
  • Portable Solar Panels — Foldable, rigid, and flexible panels from brands like ACOPOWER for camp, vehicle, or rooftop use
  • Portable Power Stations — BLUETTI and other trusted brands for grab-and-go power
  • EMP Protection — Military-tested EMP Shield units for vehicles and homes, plus Mission Darkness Faraday bags for your electronics
  • GMRS Radios — Midland and other FCC-certified radios for off-grid communication when cell service disappears
  • Preparedness Gear — Faraday bags, go-bag essentials, and survival equipment

Our Approach

We're a lean operation and proud of it. Every product in our store is selected based on real-world testing data, community reviews, and proven track records. If we wouldn't put it in our own Jeep, we won't sell it to you.

We ship direct from US-based supplier warehouses, which means faster delivery and lower overhead that we pass on to you.

Based in Tucson, Arizona

We're headquartered in Tucson — surrounded by the kind of terrain that demands reliable off-grid gear. The Sonoran Desert is our backyard and our testing ground.
