Top rated Electricity storage

Here's a ranking of the top rated products in this category. To give you a quick overview, we've also added some key information about the products.

1. EcoFlow Stream Ultra CH-Version

The EcoFlow Stream Ultra is a compact, integrated solar hybrid system that combines a 1.92 kWh battery and a built-in micro-inverter (1200 W continuous/2300 W peak power) in a single, IP65-certified housing. This allows for DIY installation without separate inverters. The four MPPT inputs accept up to 2000 W of PV power (4 x 500 W) as well as an additional 800 W through the inverter, enabling the system to generate up to 2218 kWh annually, covering more than 70 percent of a typical household's needs, and allowing charging at low temperatures down to -20 degrees Celsius. Multiple units can be connected in series or parallel (up to 11.52 kWh storage and 12 kW PV), with Wi-Fi/Bluetooth for seamless setup and expansion via the EcoFlow app. Intelligent, AI-driven load management and AI-TOU optimization of time-of-use rates automatically allocate solar power and schedule charging cycles to minimize grid electricity costs, while real-time monitoring of generation, storage, and consumption ensures an efficient, scalable, and sustainable energy supply for the home. 

2. Anker Solix Solix Solarbank 2 extension battery

The stackable additional battery BP1600 for the two balcony power plant storage systems Anker Solix Solarbank 2 Plus and Pro allows for a modular expansion of the system capacity up to 9600 Wh.

3. Zendure LiFePO4 extension battery

Zendure AB2000 Expansion Battery 1920Wh Add-On LiFePO4

The AB2000 from Zendure is an additional battery that uses LiFePO4 technology to store excess energy generated by a balcony power plant. Thanks to its SolarFlow feature, the use of solar energy through a mini photovoltaic system is no longer limited to daytime hours. The generated energy is first used to power electrical devices. The surplus electricity is stored in the batteries and can thus be utilized in the evening or during low sunlight conditions. The SolarFlow AB2000 batteries require additional components for use, including the Smart PV Hub (sold separately), at least one solar panel, and a micro-inverter.

About the AB2000 Add-On Battery:
- Total capacity of 7,680 Wh possible (modular expansion)
- Compatible with the Zendure AB1000 add-on battery
- IP65 waterproof protection
- Monitoring and control via app possible
- 10-year manufacturer warranty
- Easy integration

How does SolarFlow work? During the day, the PV Hub directs the energy generated by the PV modules to the micro-inverter, which converts it into alternating current to power household appliances. The excess energy is intelligently stored in the batteries for use at night. This can lead to potential savings of up to 32% on your annual electricity bill. The smart control ensures efficient use of the stored energy.
