How much power can I actually store with the Solarbank 3 Pro?
The truth about capacity, usable energy and what this means for your own consumption
The Anker SOLIX Solar Bank 3 Pro is a popular one Power storage for balcony power plantsBut many users rightly ask themselves the question:
👉 “How much power can I really store – and use – with the Solarbank 3 Pro?”
In this article you will learn what the 2.68 kWh capacity In practice, this means how much energy can actually be used and what role weather, technology and usage play in this.
What does the capacity of 2.68 kWh mean for the Solar Bank 3 Pro?
The storage capacity specified by the manufacturer of 2.68 Kilowatt hours (kWh) describes the theoretical maximum amount of energy that can be stored in the internal LiFePO4 battery can be stored. In practice, however, this capacity is not fully utilized in order to conserve battery life and maximize battery life.
How much energy is actually usable?
Part of the battery is used as protective buffer reserved to avoid deep discharge and extend the service life. In addition, there is a small energy loss when loading and unloading.
🔎 Typical efficiency: approx. 90–94%
(I.e. Loss rate: etwa 6–10%
This means: From the 2,68 kWh total capacity are in everyday life approx. 2,4–2,5 kWh actually usable.

How does the storage capacity of the Solar Bank 3 Pro over time?
The Solarbank 3 Pro uses durable LiFePO4 cells, which are significantly more robust than conventional lithium-ion batteries. According to the manufacturer, over 6.000 charge cycles possible where the remaining capacity is 80% Even after years of daily use, the storage remains powerful and reliable.
How does the weather affect the performance of Solar Bank 3 Pro?
How much energy you can store depends not only on the storage system itself, but primarily on the output of your PV modules. In the summer months, your balcony power station can often fully charge the Solarbank 3 Pro – in winter, however, it can often only partially charge it.
| factor | Effect on charging performance |
|---|---|
| Hours of sunshine | More sun = more yield |
| Module alignment | South = optimal |
| Shading | Reduces daily yield |
| outside temperature | Slight efficiency losses in cold weather |
An 800W balcony power station can produce up to 4–5 kWh generate enough to fill the Solarbank 3 Pro. In winter, it is sometimes only 0,5–1,5 kWh, depending on location and weather.
How does it support Solar Bank 3 Pro personal consumption in everyday life?
With the Solarbank 3 Pro you can store solar power generated during the day and use it in the evening – for example for:
-
Household appliances such as washing machines, refrigerators or dishwashers
-
Lighting and consumer electronics
-
Charging e-bikes or smartphones
This will reduce your grid power consumption and make you more independent from electricity prices.
How can the charge level of the Solar Bank 3 Pro monitor?
The Anchor App offers you an overview of:
-
Current charge level in %
-
Input and output power in watts
-
Charging and discharging process
-
System messages and error messages
The app is intuitive to use and allows you to control your system remotely.
Conclusion
| Technical information | Practical value |
|---|---|
| rated capacity | 2,68 kWh |
| Usable capacity | approx. 2,4–2,5 kWh |
| Charging frequency in summer | possible daily |
| Charging frequency in winter | often only partially loaded |
| Service life (cycles) | >6.000 at >80% remaining capacity |
The Solar Bank 3 Pro offers a nominal capacity of 2,68 kWh – in everyday life you can about 2,4 to 2,5 kWh really use it. Why not use the full 2,68 kWh? It's simple: A small portion is reserved as a technical buffer to protect the battery and extend its lifespan. Added to that are the minor charging and discharging losses that occur with any power storage device.
thanks one Efficiency of 90 to 94% The Solarbank 3 Pro is one of the most efficient LiFePO₄ storage systems in their class – with an energy loss of only 6–10%. For you this means: Reliable performance, long service life and a noticeable reduction in your electricity bill.
Especially in combination with a balcony power plant, you can store the electricity generated during the day and use it when you need it – for example, in the evening for lighting, Wi-Fi, the refrigerator, or your favorite TV series. more out of your PV system and make yourself a little more independent from your electricity provider.
