Plug and Play Battery 3.8kWh - STREAM Ultra + AC Pro - EcoFlow

This innovative kit combines an EcoFlow STREAM AC Pro home battery and an EcoFlow ULTRA battery with MPPT inputs for directly connecting your photovoltaic panels. Thanks to its plug & play design and intelligent control via the EcoFlow app, you benefit from solar self-consumption without grid injection, reliable backup power, and total scalability according to your needs.

⚡ How does the EcoFlow AC PRO + ULTRA Kit work?

1. First, the ULTRA battery connects directly to your solar panels via its 4 MPPT inputs (500 W max each), without needing an inverter.
2. The AC PRO battery plugs into a standard wall outlet.
3. By default, the two batteries can be linked via the supplied parallel cable, forming a unified and synchronized storage system, automatically controlled by the EcoFlow Smart Home app.
4. It is also possible to use the kit without connecting the 2 batteries, and install them in 2 separate rooms. Each then operates autonomously:
   • 2 independent 800 W grid outlets can be used to maximize self-consumption during off-peak hours.
   • Each battery can also secure a distinct group of devices, providing differentiated backup power in case of an outage.
5. In all cases, the EcoFlow mobile app allows you to monitor each battery in real-time, schedule charging cycles according to your lifestyle, and adapt your consumption to increase autonomy.

⚡ Advantages of the EcoFlow AC PRO + ULTRA Kit

This plug & play kit offers simplicity, autonomy, and energy intelligence. Thanks to its built-in artificial intelligence, each battery automatically recharges from the grid at the most advantageous times, especially during off-peak hours. The ULTRA battery complements this by charging directly from solar panels, without any additional inverter.

Depending on your needs, the 2 batteries can be synchronized via a parallel cable to form unified storage, or operate independently but cooperatively in separate rooms. You then benefit from 2 distinct grid charging points and 2 autonomous backup power sources, ideal for protecting different groups of equipment.

The entire system is fully controllable via the EcoFlow Smart Home app, which adjusts charging and discharging cycles based on your habits, weather, and electricity tariffs. You gain autonomy without sacrificing comfort.

⚡ Why choose the EcoFlow AC PRO + ULTRA Kit?

This intelligent hybrid system offers the best of both worlds: direct solar charging thanks to the ULTRA's 4 MPPT inputs, and optimized grid charging with the built-in AI in both batteries.

It adapts to all profiles and configurations, with or without solar panels. Its automatic control, simplified installation, and scalability make it an ideal solution to enhance your energy independence without injecting into the grid.

This 2-battery pack can save you up to €1224 per year*, by combining intelligent charging controlled by the built-in AI and solar production that can be directly injected into the ULTRA battery.

This kit is scalable: add up to 6 AC Pro and/or Ultra batteries to reach a capacity of 11.52 kWh, without modifying your installation.

⚡ Compatible Equipment

The EcoFlow AC PRO + ULTRA Kit can power:

• Household appliances (refrigerator, washing machine, etc.)
• Sensitive equipment (internet box, computers, medical devices)
• Home automation systems and connected devices
• The kit is 100% compatible with all standard photovoltaic panels, without an inverter, thanks to the ULTRA battery's MPPT inputs.
• The Smart Meter (optional) allows for global management of the electrical installation. It communicates with the EcoFlow app to optimize the use of each battery based on the home's actual consumption.
  ⚠️ With a solar self-consumption installation, this meter is essential for managing surplus production. Without it, available energy cannot be detected.
• The Smart Plug 2 (optional) allows real-time monitoring of connected device consumption and remote control, for precise and personalized energy management.

⚠️ Safety Information & Legal Notices

Each battery or pair of batteries must be connected to a dedicated wall outlet, protected by a 16 A circuit breaker and a 30 mA residual current device, with compliant grounding.

Multi-sockets are strictly prohibited. Failure to comply with these recommendations may compromise safety and void the manufacturer's warranty.
