Grand Design RVs has tapped Volta Power Systems for its newest offering of off-grid towables. Integrated with the best-selling Momentum fifth wheel and others, the systems offer up to 18 kilowatt-hours in energy storage, which can run overnight air conditioning, entertainment and other high-draw appliances.
“Having a Volta-equipped trailer means all the power you need for off-grid adventures without sacrificing the comfort you want from your home base,” said Lance Lees, product manager for the Momentum brand at Grand Design. “Quiet power also enables our customers to sleep more peacefully and securely without running a noisy generator at night.”
Volta and Grand Design are debuting their partnership with an Adventure Without Limits demonstration at the SEMA Show in Las Vegas this week. The demo included a Grand Design Momentum fifth wheel toy hauler connected with a Dodge RAM tow vehicle and TOMCAR TX4 electric ATV. A secondary 9,000-watt alternator on the RAM charges a 40 kilowatt-hour storage system on the rig while driving or idling. In turn, the trailer is upfitted with exportable power to recharge the TOMCAR. Topping off the demo is a massive 2,250-watt solar array from Future Solutions, which maintains an eco-friendly charge and can extend runtime for hours or days.
“This is the future of off-grid adventure,” said Jack Johnson, co-founder and chief technology officer at Volta Power Systems. “With a unit like this demo, you can run your electric 4×4 up and down the mountain all day, and still have enough power to recharge it and run your AC when you get back to the RV.”
With the announcement and demo unit at SEMA, Grand Design is now taking preorders for Volta-equipped towables with deliveries in early 2022. Standard options begin with 6 kilowatt-hours of storage and 3,200 watts of AC power, which can run lighting, entertainment and refrigeration. Advanced systems top off at 18 kilowatt-hours with 6,400 watts of AC power for additional amenities like all-day air conditioning (or several days depending on weather). The base units charge from shore and an MPPT solar controller.
Interested customers can also work with an approved retrofit dealer to upgrade their tow vehicle with the NITRO secondary alternator charge system or their trailer with L1 or L2 charging for EV toys.
