The company bills it as the ‘world’s first’ combined solar pavilion and battery deck. The OS1 puts solar panels in the pavilion roof and batteries beneath the deck, giving homeowners a way to generate and store electricity without altering the roof of their house. A full-size unit at booth W17153 will give visitors a look at both components and the electrical wall that connects them. Outer Spaces will offer the OS1 in two sizes. The 12-by-12-foot model has about 2.5 kW of solar capacity, while the 12-by24-foot version has about 5 kW. Beneath the floor, slim lithium iron phosphate battery modules lie flat in dedicated compartments, leaving the deck clear for furniture and appliances.
Homeowners can configure the system with one to eight modules, for up to 62.64 kWh of storage. The pavilion’s electrical wall houses the hybrid inverter, the OS1 DC Hub, and the distribution equipment. “We designed OS1 around the battery from day one, so the cooling, waterproofing, and wiring live inside the frame. It’s modular and easy to assemble on-site,” said Jiake Liu, co-founder and chief executive of Outer Spaces. The OS1 has a rated power output of up to 11.4 kVA. Outer Spaces said the system can start equipment with large motors, including air conditioners and heat pumps.
Whether it can back up an entire home during an outage depends on how the system is configured and what equipment is connected. Owners can control the system through an app or a web portal. They can choose among modes for using stored power at home, managing electricity use around time-of-use rates, or keeping power in reserve for outages. The system is also designed to participate in virtual power plants where regional programs allow it, linking the batteries with other distributed energy resources. The pavilion is assembled on-site, with a licensed electrician handling the final connection to the home. Outer Spaces plans to meet with builders and installers at RE+ as it recruits its first Southern California partners for 2027.
