The first customer is Airstream, the iconic maker of riveted aluminum travel trailers. Earlier this week, Airstream unveiled its new Trade Wind 27FB, which features a Harbinger power system designed to support off-grid camping, run air conditioning, and integrate with solar power.

The Trade Wind 27FB's next-generation energy system delivers up to 18.5 kWh of battery capacity—the largest in Airstream's lineup—paired with a 600W rooftop solar array for efficient renewable energy capture. A fully inverted electrical system with a 5,000W inverter supports 50-amp service, allowing dual air conditioners with heat pumps to run seamlessly even when camping off-grid and away from traditional shore power.
"By introducing automotive battery systems to the RV market, we're helping set a new standard for off-grid performance. At the same time, we are demonstrating that high-quality, American-made battery systems can be delivered at a price point that makes sense for customers," said John Harris, co-founder and CEO, Harbinger.
At its California facility, Harbinger develops and builds its own high-voltage battery systems from the ground up. By keeping design and manufacturing in-house, the company claims it tightens control over quality while improving reliability and cost efficiency. The systems use lithium-ion cells supplied by Panasonic Energy, and are engineered to meet demanding automotive-grade standards.

The Harbinger Power System, the company explains, actively manages battery health, temperature, and power flow to ensure reliable operation. Automated controls prevent over-discharge, while liquid cooling protects the battery in extreme weather conditions. Another cool feature, a dedicated display, provides users real-time insight into energy use and available power from batteries, solar, or shore connections.
"The Airstream Trade Wind 27FB has the most capable off-grid electrical system we've ever offered in our travel trailer product line," said Bob Wheeler, Airstream president and CEO. "By integrating Harbinger's industry-leading battery technology in our travel trailers, our customers can stay off-grid longer with confidence."
