Background: The Ace 1500 was developed against the backdrop of rising electricity prices, high demand for household power and the popularization of time-of-use tariffs, taking into account the lack of off-grid functionality of the original SolarFlow balcony energy storage system, limited application scenarios and the difficulty of winter maintenance. It works in tandem with the battery system and is designed for outdoor adventures and emergency power backup, and incorporates a TOU function to adapt to changing electricity demand and provide a smarter, more flexible power solution.Features: The modular design of the Ace 1500 provides a convenient upgrade path for those who already have a SolarFlow system, especially when pursuing the freedom of off-grid electricity use and maximizing economic efficiency. Combined with the Add-on Battery system, the Ace 1500 is capable of 1500W AC output power, which not only supports fast utility charging, but also works with the Hub and micro-reverse system to realize long-time battery power supply to the home, significantly reducing electricity costs. Its long-term power supply capability for low power loads and UPS switching time of less than 20ms ensures the stable operation of home appliances, including refrigerators, without being affected by low standby power. In addition, the up to 10-year battery warranty and 15-year service life commitment highlight the product's durability and user return on investment.Design: The Ace 1500 combines the brand's consistent simplicity and pragmatism with high-quality metal buttons and hidden carrying handles on both sides, making it both easy to operate and easy to carry, even for children. The use of eco-friendly plastic not only shows respect for the environment, but also gives the product a lightweight texture, further enhancing its portability.Concept: The Ace 1500 responds to the modern pursuit of outdoor adventure, emergency preparedness, and energy-saving lifestyles, and is designed with the user's expectations for flexible, autonomous, and sustainable energy solutions in mind, demonstrating the brand's philosophy of green living.Safety and usability: The Ace 1500 is controlled by a smart APP that realizes the TOU function, allowing users to flexibly schedule charging and discharging according to fluctuations in electricity prices, simplifying energy management.The enhancement of the MPPT technology accelerates the battery charging speed, while the added AC input function ensures power supply even in low light conditions. The modular stacking design simplifies the installation and maintenance process. Users do not need complex wiring and can simply place or replace batteries to meet the power needs of different scenarios, and this design greatly enhances the product's ease-of-use and safety, ensuring worry-free power supply to the home under any circumstances.
