Introduction: The Anker SOLIX Solarbank 3 Pro and bidirectional charging

The Anker SOLIX Solarbank 3 Pro is a modern battery storage system with a capacity of 2,68 kWh, specifically designed for plug-and-play solar systems such as balcony power plants.

A particular highlight: It supports the so-called “BiDi Store“ – so charging in two directions:

• with self-generated PV electricity

• or with mains power (if activated)

However, many users are unsure what BiDi charging actually means – and when the solar bank will actually charge with solar power instead of grid power. In this context, questions frequently arise about Anker Solix 3 per bidirectional load as well as Anker Solix download from the network .

How does BiDi charging work on the Solarbank 3 Pro?

The Anker SOLIX Solarbank 3 Pro is an intelligent Balcony power plant storage with support for bidirectional charging - also known as BiDi StoreThis means: The solar bank can be used with excess PV power It can be charged with both mains and AC power. It automatically detects which power source is currently available and prioritizes self-generated solar powerto maximize self-consumption.

In case of PV surplus – i.e. when the PV production is higher than the current household consumption – the solar bank charges exclusively with solar powerThis is the ideal situation and leads to optimal use of solar energy.

If the PV output is not sufficient, for example on cloudy days or when power consumption is high, the solar bank charges additionally with mains power, provided that the mains charging is in the AnkerThe app is activated. This keeps the system flexible and ensures that the battery is reliably charged even with fluctuating PV generation.

If no PV power is available and the grid charging is active, the battery fully charged with mains power – even if this is not desired for ecological or financial reasons.

📌 Important: If you only want to use PV surplus to charge your solar bank, you can easily use the grid charging in the app deactivateThis way, you avoid unwanted grid power usage and make your PV system significantly more efficient.

4. Save Changes

The Anker Solarbank 3 Pro is now loading exclusively with surplus solar power – ideal for anyone who wants to reduce electricity costs and avoid grid dependency.

👉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 Solarbank 3 Pro central storage and distribution of solar energy.

Don't feed electricity back into the grid? No problem!

Do you also want to prevent your system from feeding electricity into the public grid? This is also the case with the Anker SOLIX Solarbank 3 Pro easily possible – in combination with a compatible smart meter.

This function is particularly useful in rentWherein Balcony power plants without registration or in cases where no EEG remuneration This way, you retain full control over your own consumption and avoid unwanted feed-in.

Important: Deactivating the grid feed-in works only with a compatible smart meterWithout this, the system cannot accurately determine how much power is being fed in – so it is essential for this function.

Conclusion: Flexible charging with maximum control

The Anker SOLIX Solarbank 3 Pro offers you not only smart PV surplus utilization, but also full control over when and how charging takes place.
Whether with or without grid, with or without feed-in – you decide how your electricity flows.

If you are one efficient, flexible and easily controllable storage system for your home, the Solar Bank Pro 3 exactly the right choice.
