Pebble Turns the 2027 Flow Into a Rolling Microgrid With Up to 4 kW of Solar

Pebble has rolled out a meaningful update to its flagship fifth-wheel trailer for the 2027 model year, and the headline change is energy: the Flow can now function as a genuine microgrid on wheels, capable of powering both your campsite and your home.

The centerpiece is a new external solar integrator that plugs straight into the trailer and adds a pigtail with four pairs of solar MC4 connectors. It allows owners to add as much as 3 kW of extra solar on top of the 1.1 kW array already mounted on the roof, pushing total solar input toward 4 kW. That harvested energy feeds the Flow’s 45 kWh iron phosphate battery. Pebble has also partnered with Jackery so its 500W foldable panels integrate cleanly with the system. The energy upgrade ships in December 2026, and existing owners can retrofit their units.

More solar means more flexibility in every season. Owners can use the trailer as a backup power source during grid outages, run the air conditioner for longer stretches, or even charge an electric vehicle from the Flow. Because it handles its own generation and consumption so capably, the trailer can plausibly serve as an accessory dwelling unit when guests visit, a non-traditional but practical use case.

Inside, the biggest change for 2027 is a new twin-bed configuration that replaces the queen-size Murphy bed that was previously the only option. The two twins are fixed to the floor, opening up additional storage beneath, and the layout includes a narrow aisle between them so occupants can walk up to the side of the bed before sitting down. Couples with older children may find this especially appealing, with the convertible dinette at the rear sleeping two adults. A new clay colorway also joins the palette. Electrochromatic glass on all exterior windows, along with the bathroom and shower section, provides genuine privacy in a small space.

On the software side, Pebble is shipping Pebble OS 2 as an over-the-air update for existing owners and natively on the 2027 Flow. The release introduces Boost Mode, which unlocks the full 40 kW (54 horsepower) of tow assist from the hub motors mounted in each wheel. Those motors read whether the tow vehicle is accelerating or braking and respond accordingly, accelerating to match speed or engaging regeneration. Combined with the trailer’s aerodynamics and active aerocap, the system can stretch range substantially — upward of 250 miles per charge when starting with a full EV battery and a fully charged Flow, versus roughly 100 miles for a comparable 6,000 lb trailer. The motors also enable remote-controlled maneuvering via an iPad, simplifying hitching and even letting owners drive the Flow directly into a fast-charging stall. Fast charging is supported as well.

Taken together, the 2027 Flow is less a conventional fifth wheel and more a self-contained energy and living platform — one that makes towing easier and adventuring more comfortable than the segment has traditionally allowed.
