WENZHOU – November 06, 2026 -- Erayak Power Solution Group (Nasdaq: RAYA) said the new Ruike Electronics (Wenzhou) facility has entered final construction acceptance. The energy storage portion carries a planned annual design capacity of 150 MWh, and the company's 16 kW tri-fuel inverter generator is approaching pilot production.
Ruike facility adds capacity, with phased start-up through Q4 2027
The Ruike facility adds to ERAYAK's manufacturing footprint and does not replace existing capacity. The company expects acceptance of all main buildings to be completed in the first quarter of 2027. Production on relevant lines is planned to start in phases from the fourth quarter of 2026 through the fourth quarter of 2027, subject to acceptance results, equipment commissioning and product introduction schedules.
The 150 MWh figure is a design-capacity number. It is not an estimate of initial effective capacity or actual output, and it does not cover generator production. The site will primarily serve next-generation portable tri-fuel generators and battery energy storage products.
16 kW tri-fuel generator targets gasoline, propane and natural gas
The independently developed single-unit design targets up to 16 kW of rated output across the three fuels. A two-unit parallel configuration is planned, with a targeted combined output in the 32 kW class. Rated output may differ by fuel type, and final ratings and parallel-operation capability remain subject to testing and validation. Pilot production will focus on process readiness, manufacturing consistency and product verification. ERAYAK is also exploring automatic transfer switch (ATS) compatibility for home backup.
Storage roadmap spans six output classes from 1.8 kW to 13 kW
The battery programs target approximately 1.8-2 kW, 3.6-4 kW, 5 kW, 7 kW, 10 kW and 13 kW. The near-term priority is a portable unit of about 1.8-2 kW and 1 kWh, aimed at camping, mobile power and short-duration backup of essential household loads. A later 3.6-4 kW class would carry around 2 kWh of base storage. ERAYAK is also developing an approximately 90 Wh USB-C power bank. All figures are development targets and may change.
Two hybrid architectures pair engines with batteries
The first design integrates a fuel-powered generating unit, battery storage, power conversion and controls in one portable system. The engine would replenish energy while the battery handles rapid load changes. The stated aim is better power density, weight, size and fuel utilization for defined loads.
The second design pairs an outdoor generator with a separate battery unit and coordinated energy management for home backup. The battery could supply household loads from an approved indoor or other permitted location. Generators, including integrated hybrid units with an engine, must always be operated outdoors. UPS-style continuity is under exploration, and performance and installation requirements remain subject to engineering validation.
"Fuel-powered generation offers endurance, while batteries can respond quickly to changing demand," said CEO Lingyi Kong.
North America leads own-brand rollout; ODM work runs in parallel
ERAYAK expects to prioritize North American rollout of its own-brand products through existing retail and distribution channels. Its commercially available 6800PT tri-fuel inverter generator is separate from the new development programs. The company also plans to use available manufacturing resources and shared technology platforms to pursue customized development and original design manufacturing (ODM) opportunities. None of the new generator, storage or hybrid platforms is yet offered for commercial sale, and the company has not given launch timing.
