About us

Thanks for visiting OffTheGridRVs for all your solar needs

We specialize in custom RV solar installations and lithium conversions. We are not a mass production shop. We are located at 1130 N Central Blvd, Quartzsite, AZ 85346, 1 mile north of Main Street/I-10 on the corner of Camel and Hwy 95, on the west side.

We have the largest selection and best prices on all Victron Energy products: MultiPlus II inverters, Quattros, touch screens, lithium batteries, Cerbo GX, Lynx Distributors and everything in between.

We have the only vehicle UL-listed lithium batteries in town that are start and deep cycle batteries, with built-in heaters and Bluetooth, designed and UL approved for auxiliary vehicle power: Lithionics Battery.

We're a seasonal shop, open mainly October through April. Hours & directions

What we do

Power systems for people who'd rather boondock

From adding a single panel to a full lithium and inverter build for full-time work-from-the-road, we design each system to fit your rig and how you use it.

Custom RV Solar Installs

Roof panels, charge controllers and wiring designed for your RV, with clean runs and tidy work you'll be proud to show off. That includes our own tilting panel brackets.

Lithium Conversions

Swap out lead-acid for lithium and get more usable power with less weight. We're Quartzsite's exclusive Lithionics dealer, and our new Victron installs are built around Victron's Lithium NG batteries. Newmar owners: we can expand your factory Lithionics bank.

System Redos & Inspections

Not happy with work done somewhere else? We dig into the whole system, find what's unsafe or undersized, and fix it properly. Customers bring us installs from other shops to redo.

Victron Showroom

We're an authorized Victron Energy dealer with the largest Victron selection in town: MultiPlus-II, Quattro, Cerbo GX, Lynx and more. We'll meet or beat any price in town or online. Visit the showroom

Made in our shop

Custom tilting solar brackets, machined in-house

Off-the-shelf mounts don't fit every roof or every way of camping. So we make our own. Our tilting solar panel brackets are cut on our CNC mill right here in the shop, so you can angle panels toward the low winter sun and get more harvest from the same roof.

  • Designed and built in-house by people who install them every day
  • Made to fit your rig, not a one-size-fits-all kit
  • We fabricate in-house with our MIG and TIG welders and plasma cutter, including custom aluminum racks with remote-control tilt
  • Coming soon: we're adding a full-size CNC machining center to expand what we can fabricate in-house

Newmar owners · Quartzsite's exclusive Lithionics dealer

Expand the Lithionics system in your Newmar

Many Newmar diesel pushers come factory-equipped with Lithionics lithium. Lithionics comes standard on the Essex, Newmar's top of the line, and is available on other Newmar models. On the Essex, Newmar also offers a third battery as a factory option, so these systems have room to grow.

Factory setups vary by model and year. We see both 630 Ah and 320 Ah Lithionics modules, paired with an external 400 A BMS. We work on these systems every season and can add matching modules to grow your bank.

On models below the Essex, there's room for a 320 Ah module right next to the factory 630, an easy way to add capacity.

As Quartzsite's exclusive Lithionics dealer, we can pick up where the factory left off:

  • Expand your existing Lithionics bank with matching Lithionics batteries
  • Convert an AGM coach to a factory-style Lithionics system
  • Add solar so you can boondock longer without running the generator
  • Integrate Victron charging and monitoring with your system

Essex, New Aire, Mountain Aire, London Aire and other Newmar Class A coaches. Not sure what your coach has? Call with your year and model and we'll help you find out.

2022 New Aire: factory AGM to a factory-style Lithionics system

This New Aire left the factory with 6V AGM batteries. We converted it to dual 630 Ah Lithionics modules with built-in heaters and a 400 A external BMS that talks over CAN bus to the coach's Silverleaf system. We configured the lithium clone file and uploaded it into Silverleaf, so the coach runs its new bank like a factory lithium Newmar.

  • 2400 W of solar on custom 80/20 aluminum racks, bolted to the factory roof-line gussets
  • Dual Victron SmartSolar MPPT 150/100 charge controllers
  • Victron Lynx Distributor, 5k Quattro inverter/charger, Cerbo GX and GX Touch 70

Have an AGM-equipped Newmar? It can be converted to a factory-style Lithionics system that talks to Silverleaf. See the solar install in our gallery

2023 Essex: six 320 Ah modules, and the hot-cable problem solved

This Essex came with dual 320 Ah Lithionics modules and room for a third. The owner added the third, then needed more, so we added three more for six 320 Ah modules in all. We modified the battery rack in-house on our MIG welder to carry the bigger bank.

Before the coach came to us, the owner had been dealing with cables getting extremely hot. When it came in for the install and we tore into the bay, we found the cause. The Essex comes with dual Xantrex SW3012 inverters, and the plans call for double 4/0 or 350 MCM cable from the BMS to the bus bars. At the factory, Newmar used single 4/0 with hammer crimps.

We removed all of those cables and made new ones with tinned copper lugs, crimped on our battery-powered hydraulic crimper.

Leisure Travel Vans (LTV) owners

Solar and lithium for your Leisure Travel Van

We often work on Leisure Travel Vans, especially the LTV Unity. A van roof doesn't leave much room around the air conditioner and vents, so we lay out each array to fit, often on our own tilt brackets.

  • Solar laid out for your LTV, like the eight 100W panels in the photo
  • Two kinds of tilt: individual manual tilt brackets for each panel, machined on our CNC mill, or a remote-control tilt rack on the Unity
  • Lithium upgrades with the Lithionics GTX12V320, which fits under the step where the factory 6V batteries were and can also start the generator
  • Victron charging and monitoring from solar, shore power and your alternator

Our biggest LTV builds have included up to three GTX12V320 batteries and a dedicated 280A second alternator.
