1. Introduction

Zendure has established itself as a major player in the field of balcony power plants and storage solutions with its SolarFlow series. However, anyone looking for an add-on module for existing PV systems or balcony power plants today will quickly come across three very similar models: AB2000, AB2000S and AB2000XAll three offer the same capacity of 1.920 Wh, but there are key differences in features, safety, and performance that are relevant to the purchasing decision. In this article, we'll explain how the models differ and how they're compatible.

2. Common basis of all models

All three variants use lithium iron phosphate cells (LiFePO₄) and reach over 6.000 charge cycles to 70% capacity limit. Thanks to IP65 certification, they are protected against dust and water jets. Furthermore, all models feature integrated self-heating, enabling reliable operation even in winter temperatures down to -20°C. The batteries integrate seamlessly into existing Zendure systems such as PV Hub 1200, PV Hub 2000, Hyper 2000 or Ace 1500 integrate.

3. Model comparison: AB2000 vs. AB2000S vs. AB2000X

The differences lie in the details: AB2000S offers compared to the basic version AB2000 an integrated heater for winter use and an aerosol fire extinguishing system, making the storage tank particularly suitable for indoor use and cold regions. AB2000X further expands these features with a higher charging and discharging power of up to 1.920 W per module and the ability to stack up to six modules, depending on the host system. Despite these differences, all three variants are fully compatible and can be combined in a single system.

4. Recommendation: Which model suits you?

Choosing the right model depends on individual requirements. Those looking for a cost-effective standard solution will be happy with the AB2000 well served. Users who need additional protection in cold regions or indoors benefit from the AB2000S with heating function and fire extinguishing system. If you need the highest performance and maximum flexibility, you should AB2000X Choose one that offers higher output power and allows for more modules to be stacked. Thanks to complete compatibility, all three models can be flexibly combined, allowing the system to adapt to changing requirements.

5. Fazit

Even if the model names seem confusing at first glance, the differences are clearly structured: AB2000 stands for solid basic technology, AB2000S complements safety and winter functions, and AB2000X offers additional performance and expandability. All variants are compatible and ensure high cycle stability, IP65 protection and reliable operation in winter conditions. The decision ultimately depends on how important safety, performance, and flexibility are to the user.
