Frequently Asked Questions

A home battery stores the power your solar panels generate during the day, so you can use it later.
A battery can also purchase power at the most favorable times when using a dynamic energy contract. This tool is AI-powered for most brands.

When the sun shines, your solar panels often produce more energy than you use at that moment. The home battery stores this excess solar energy. In the evening or when there's little sun, your home automatically uses the stored energy. This means you need to draw less power from the grid, saving you money on your energy bill.
With the right home battery, you'll no longer feed power back into the grid. Your self-generated power will be used when you need it.

With a home battery, you use more of your own green energy, save costs, and become less dependent on the energy grid.

It's best to install a home battery in a safe and well-ventilated location, such as a garage, basement, or utility room. This location ensures optimal operation and a longer battery lifespan.
Ideally, have the battery installed near the inverter or meter box to minimize energy loss. Some models can also be installed outdoors, provided they are weatherproof and protected from extreme temperatures.
We at AboutWatt are happy to advise you on this!

The price of a home battery depends on the brand, the capacity (kWh), and the installation costs. On average, a home battery costs between €4,000 and €10,000, including installation.
There is a cheaper alternative in the form of Plug & Play batteries , these are compact batteries that cost an average of €1,000 to €4,000 including installation.

The final price also depends on:

• the brand (e.g. Anker Solix, Sigenergy, Huawei or Marstek)
• the battery type (lithium-ion or alternative);
• whether you combine the battery with solar panels or an existing installation.
• possible subsidies or premiums in your region.

A home battery is generally not dangerous, as long as it's installed and used correctly. Most modern home batteries are equipped with multiple safety mechanisms that prevent overheating, overcharging, or short-circuiting.

In addition, they are extensively tested and certified according to European safety standards.

Always have the installation carried out by a certified installer – this is not only safer, but also necessary to maintain the warranty and insurance.

A backup function with a home battery ensures you still have electricity during a power outage . The battery then temporarily supplies power to essential appliances in your home, such as lights, refrigerators, or Wi-Fi modems.

Not every home battery has a backup function as standard; sometimes additional equipment is required, such as a special inverter or emergency power module.

In short: with a backup, your home will continue to receive (partial) power, even if the grid goes down. Without a backup, the battery only works when there's power from the grid.

AboutWatt's range of plug & play batteries and home batteries offers various backup options. Feel free to request a free consultation if you're unsure whether you're making the right choice!

You can connect up to three Solarbank 3 E2700 Pro units within one home energy system to provide a maximum AC power of 3600 W.
Want a higher total output? Then you can use the Power Dock . It supports parallel connection of up to four Solarbank units , good for a total output of up to 4800 W. The Power Dock also allows you to connect an EV charger .

Please note: The installation of the Power Dock must be carried out by a certified electrician.

Currently , only the Solarbank 3 E2700 Pro is suitable for directly connecting and using multiple units within one home energy system.
The other Solarbank models do not offer this plug and play functionality, but can be connected in parallel via the Power Dock .

Please note: The Solarbank 2 E1600 AC is expected to receive Power Dock support at the end of December.

The main differences are:

1. Number of units supported
   Plug-and-play: maximum 3 Solarbank 3 E2700 Pro units.
   Power Dock: maximum 4 units connected in parallel.
2. Maximum output power
   Plug and play: up to 3600 W total power.
   Power Dock: up to 4800 W total power.
3. Installation requirements
   Plug and play: connect immediately, no professional required.
   Power Dock: Must be installed by a certified electrician .
4. EV charging
   Plug and play: Does not support EV charging stations.
   Power Dock: Supports single-phase and three-phase EV chargers.
5. Energy management
   Plug and play: standard power management.
   Power Dock: Three-phase output and unified energy management for the entire system.
6. Compatibility
   Plug and play: Solarbank 3 E2700 Pro only.
   Power Dock: Supports mixed Solarbank models and is future-proof for new products.
7. Meter connection
   Plug and play: compatible with P1 Meter access.
   Power Dock: Works with Anker Smart Meter , Shelly 3EM or Shelly Pro 3EM .

Please note the following:

1. Update the Anker app
   To properly configure multiple units, make sure your Anker app is updated to version 3.12.0 or later .
2. Registration with grid operator
   Register your system (if applicable) with the local grid operator and relevant authorities so that the installation complies with all regulations and can be safely put into operation.
3. Setting the output power
   When using multiple Solarbank 3 E2700 Pro units, you can set the total output power to 800 W, 1200 W, 2400 W, or 3600 W.
   If the set power exceeds 800 W , professional installation is strongly recommended . This prevents safety risks, potential equipment damage, and regulatory issues.

Expand existing energy system

If you want to add one or more Solarbank 3 E2700 Pro units to an existing home energy system, follow these steps:

1. Open the energy system homepage in the Anker app.
2. Tap the gear icon at the top right to access settings.
3. Select 'Manage Devices' .
4. Tap the '+' icon at the top right to add additional devices (e.g. Solarbank 3, smart meters or smart sockets).
5. Make sure that all devices within the same system are connected to the same WiFi network .
   

Setting up a new home energy system

1. Installing the Solarbank 3 E2700 Pro for the first time? Follow these steps:
