1. 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 function, 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. Any surplus electricity is stored in the batteries, allowing it to be used 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 surplus 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 intelligent control ensures efficient use of the stored energy.

2. Zendure SolarFlow AB2000S
The AB2000S from Zendure is a next-generation LiFePO4 expansion battery that stores excess energy generated by your balcony power plant. You can expect a wide range of new technologies and safety features. Unlike its predecessor, the AB2000, even more emphasis is placed on safety and durability for your system. One constant is that, thanks to the SolarFlow system, the supply of solar energy through a mini PV system is no longer limited to daytime hours. The energy generated is stored in the batteries after powering the consumers, allowing it to be used at night or during periods of low sunlight. The battery is compatible with the entire SolarFlow range.
Delivery includes: 1x Zendure SolarFlow AB2000S expansion battery 1920Wh Add-On LiFePO4.
