Space Craft MFG, a full-custom towable RV builder, and Volta Power Systems have partnered to debut a 54-foot luxury trailer with enough power and water to spend several weeks completely off-grid. The prototype trailer, revealed at last week’s Florida RV SuperShow, features the largest li-ion system Volta has ever installed on a towable with 108kWh of storage, the company said. For long stays, a 10,000-watt slide out array of solar panels help to maintain the system, and there are 485 gallons of fresh water storage to increase flexibility when staying in arid climates. Space Craft designed the trailer with a convertible bedroom/garage to transport and charge a Volvo XC40 electric SUV.
“Our customer’s goal was to maximize their boondocking capability for extended to indefinite periods of time. To accomplish that, we utilize the ability to remove black water and bring fresh water with the semi-tractor, and we integrated a self-replenishing clean energy strategy with a huge solar array and the Volta li-ion system,” said Greg Wallman, CEO at Space Craft MFG. “The customer also wanted the RV to be as comfortable as possible, designed to fit their needs. Amenities like an LG mini-split HVAC, floor heating and residential appliances redefine what it means to live off-grid.”
The Volta system on board stores enough energy to run the trailer’s residential appliances, air conditioning, lighting, entertainment and more for several days without the use of a backup generator. In sunny weather, the solar system is rated to collect up to 50 kilowatt-hours over the course of the day, which helps maintain battery levels or top off the EV. However, the system is also chargeable from shore, generator and a custom secondary alternator installed in the towing semi-tractor so that the unit can charge while driving.
“People want more than just a clean battery. They want all the power they need to create an experience just like home,” said Jack Johnson, co-founder and chief technology officer of Volta Power Systems. “The customer will be able to take a day trip in their electric vehicle while their Volta system is recharged by the solar panels. When they return, they can plug their car into the L2 charger, relax in the AC, and even cook dinner on electric appliances without any noise or emissions.”
Enhancing the at-home, high-comfort feel, the vehicle will contain residential appliances, heated tile floors, a 50-inch fireplace, tankless hot water and Starlink internet.
