EcoFlow STREAM AC Pro with 1.92 kWh battery

EcoFlow STREAM AC Pro is an advanced plug-and-play solar storage solution, designed for those who want to enhance their home solar system with a versatile and easy-to-install battery. With a capacity of 1.92 kWh and the possibility of expanding up to 11.52 kWh by connecting up to six units, this battery integrates perfectly with third-party microinverters or with the EcoFlow STREAM series, such as the STREAM Ultra or Pro. Thanks to the AC coupling technology, it connects directly to standard wall outlets, eliminating the need for complex wiring and making it ideal for tenants or those looking for a solution without professional intervention. Its capacity to power appliances up to 2300W makes it perfect for high-drain appliances such as dishwashers, ovens or refrigerators, helping to reduce electricity bills by up to 71.3% of the household needs.

The STREAM AC Pro is designed to maximize the efficiency of solar energy, thanks to its compatibility with microinverters of any brand through standard AC outlets. With an AC output of 1200W per battery, it can reach 2300W in auto-boost mode when paired with another STREAM AC Pro or STREAM Ultra unit via a parallel cable. This allows you to power high-powered appliances directly with solar energy, reducing your dependence on the electrical grid. Additionally, the built-in battery provides off-grid power and backup during blackouts by connecting appliances directly to its dual AC outlets. AI load balancing technology ensures that if a battery in one room runs low, power is automatically redirected from another nearby unit, keeping essential devices running without interruption.

Intelligent energy management is one of the strengths of STREAM AC Pro. Via the EcoFlow app, the AI-TOU (Time-of-Use) mode analyses local electricity rates, weather data and consumption patterns to optimise charging and discharging, charging the battery during low-cost times and using stored energy when prices are high. This feature, which requires a premium subscription, can reduce energy costs by up to 50% per year. The app also allows for real-time monitoring, remote management of devices and customisation of energy routines, thanks to Wi-Fi 6 connectivity and wireless battery sharing technology. The system integrates with smart energy brands like Shelly and Tibber, using smart meters and plugs to optimise the use of excess solar energy, such as powering sprinklers or e-bikes.

Scalability is another key aspect: STREAM AC Pro starts at 1.92 kWh but can be expanded to 11.52 kWh by connecting up to six units, with a total solar input of up to 12 kW (24 MPPT) when paired with systems like STREAM Ultra. Plug-and-play installation requires no drilling or electricians, making the system accessible even for renters. The LFP battery offers exceptional battery life, maintaining 70% capacity after 6,000 cycles—approximately 15 years of reliable use—backed by a 10-year warranty. The fanless thermal design ensures quiet operation under 30 dB, while the IP65 rating ensures resistance to rain and dust, making the battery suitable for both indoor and outdoor use. The system also works in extreme temperatures, down to -20°C, thanks to self-heating technology.

The compact and modern design of the STREAM AC Pro, with an anodized aluminum finish and 40% smaller than traditional systems, fits into any home environment. It can be placed behind curtains, next to plants, or mounted on the wall as a functional decorative element. Security features include real-time load monitoring, overload and overheat protection, and a 0.7 second safe voltage drop when disconnected, ensuring reliable operation. During power outages, STREAM AC Pro provides power to essential appliances connected to its AC outlets, using its internal battery or solar energy. While it can integrate with the grid to store excess energy, in many configurations it does not feed energy back to the grid, focusing on optimizing home consumption.

In summary, EcoFlow STREAM AC Pro is a versatile solar storage solution that combines ease of use, universal compatibility, and intelligent energy management. With its DIY installation, long-lasting battery and AI capabilities, it is ideal for those who want to reduce energy costs and increase energy independence without the complexity of traditional solar systems.
