Who his Solar Bank 3 Pro wants to expand, is quickly faced with the question: BP1600 or BP2700?

Both additional batteries are compatible with the system – but they differ in price, capacity, charging performance, and lifespan. In this article, we compare the two models and help you make the right decision for your Balcony Solar Panel with memory to meet.

Overview: Technical data in comparison

👉New: Anker SOLIX Power Dock

• Connection of up to 4 solar banks

• Max. 4800 W feed-in, storage expandable up to 64,4 kWh

• Supports up to 14,4 kW solar power, direct feed-in into the home grid

• Ideal for high self-consumption such as heat pumps or electric vehicles

• Scalable and future-proof (wallbox integration planned)

With the Power Dock Larger photovoltaic systems can be realized, while the Solar Bank 3 Pro central storage and distribution of solar energy.

Charging performance: Both fast – but with a subtle difference

Whoever Store PV power quickly wants, pay attention to the maximum charging power.

Both batteries enable a significant performance increase compared to the basic configuration of the Solarbank 3 Pro (1.200 W):

• BP1600: up to 2.200 W

• BP2700: up to 2.400 W

💬 Users Fox10 from the Solar Technology Forum reports:
“Host alone = 1.200 W.
With BP1600 = 2.200 W.
With BP2700 = 2.400 W. Additional batteries only increase the capacity, not the charging power."

The numbers show: If you want maximum speed, the BP2700 slightly forward.

Lifespan: Is the higher price worth it?

A big difference lies in the Cycle stability:

• BP1600 is up to 6.000 charge cycles designed

• BP2700 offers approx. 6.000 charge cycles

Those who use the storage regularly will benefit from the BP2700 through significantly longer lifespan and thus lower costs per stored kWh over the years.

Which battery is suitable for whom?

Tip: Even if you start with the BP1600, you can upgrade later if necessary – for example, with a second battery (to increase capacity, not charging speed).

Structure and flexibility

Both batteries can be easily installed using the Solarbank 3 Pro's plug-and-play system – without any specialist knowledge.
The combination can be expanded as needed, but the following applies:

A More batteries = more capacity,
❌ but no more charging power – this is technically determined by a battery.

Conclusion: BP1600 or BP2700 – a far-sighted decision

Whether you are just entering the world of balcony power plants with storage or are already looking for the right upgrade – the choice between BP1600 and BP2700 should not depend only on the price.

• The BP1600 is ideal for anyone who wants to upgrade quickly, cost-effectively and efficiently – especially in smaller households with limited power requirements.

• The BP2700 scores with more capacity, higher charging power and a significantly longer service life – an investment for all those who think about the future and strive for maximum independence.

If you want to store as much solar power as possible during the day, you should not only kWh, but also on the kW power pay attention. Because:

A well-chosen battery turns your Solarbank 3 Pro into more than just a storage device – it becomes a true energy management system.
