El Segundo – November 10, 2026 -- Outer Spaces, a startup backed by $8 million in pre-seed funding, will show its OS1 solar pavilion and battery deck in person for the first time at RE+ 2026 in Las Vegas, with scalable storage of up to 62.64 kWh and rated output of up to 11.4 kVA.
OS1 builds solar generation into a backyard pavilion roof
The system combines open-air living space with solar generation and battery storage. Panels are integrated into the pavilion roof, so homeowners add generation without modifying or penetrating the main-house roof.
OS1 comes in two sizes: a 12x12 ft unit with approximately 2.5 kW of solar and a 12x24 ft unit with approximately 5 kW.
Under-deck LFP modules scale from one to eight units
OS1 Horizon BladePack lithium iron phosphate (LFP) battery modules sit horizontally in dedicated bays below the deck, leaving the full deck surface free for furniture and appliances. Each module holds 7.83 kWh, and systems scale from one to eight modules, reaching 62.64 kWh.
An integrated electrical wall houses the hybrid inverter, the OS1 DC Hub and distribution equipment. CEO Jiake Liu said the company designed OS1 "around the battery from day one," with cooling, waterproofing and wiring inside the frame.
11.4 kVA output targets whole-home backup, including air conditioners and heat pumps
OS1 delivers up to 11.4 kVA of rated power and can start large motor loads. Whole-home backup during outages, including air conditioners and heat pumps, depends on configuration and connected loads.
Owners manage the system through an app or web portal with Self-Power, Time of Use and Backup Standby modes. It is built to be ready for virtual power plant (VPP) participation where regional programs allow.
Installer channel is the commercial focus at Booth W17153
OS1 is modular and assembled on-site, with a licensed electrician completing the connection to the home. At RE+, held November 16-19 at the Las Vegas Convention Center, the Outer Spaces team will meet installers and builders to line up its first Southern California partners for 2027.
Upfront Ventures led an $8 million pre-seed round in October
Outer Spaces launched in October with $8 million in pre-seed funding led by Upfront Ventures, with participation from Unlock Venture Partners, Mucker Capital and Genius Ventures. The company was founded in 2025 by Jiake Liu, Terry Lin and Robin Liao, who also founded the outdoor living brand Outer.
OS1 will be available starting in 2027 in Southern California and select markets nationwide, sold online and through installers, builders and developers. Pricing will be announced in early 2027.
