Anker Solarbank 4 Pro E5000: 5 kWh plugin battery
The Anker Solarbank 4 Pro E5000 is a 5 kWh home battery with up to 5,000 W of solar input. Your panels connect straight to it, it stores the surplus your home does not use, and it plugs into a socket. It expands to 30 kWh. Get it at Robinsun with the Anker Smart Meter Gen 2.
What is the Anker Solarbank 4 Pro E5000?
The Anker Solarbank 4 Pro E5000 is an all-in-one solar battery: a 5 kWh battery, a solar charge controller and an inverter in one unit.
How the Solarbank 4 Pro works
Your panels connect to four solar inputs. Each input has its own MPPT (maximum power point tracker), so panels facing different directions each give their maximum power.
The Solarbank 4 Pro supplies your home through a socket and charges the battery with the surplus. After sunset, the battery supplies your home. The Anker Smart Meter Gen 2 in your electrical panel tells the battery what your home uses, so its output matches your consumption.

Why the Anker Solarbank 4 Pro matters for you
One unit for panels and storage
Your panels connect to the battery, not to a separate micro inverter. One device converts, stores and supplies your solar power, and you control it in the Anker app.
Room to grow
Start with a few panels and add up to 12, for 5,000 W of solar input. Each BP5000 expansion battery adds 5 kWh, up to 30 kWh in total.
About €230 a year from stored power
The figure rests on three assumptions:
- About 4 kWh a day reaches your appliances. An independent Notebookcheck test measured about 89% of the 5 kWh as usable.
- The battery fills with surplus on 200 days a year.
- Each kWh you use instead of buying it saves €0.29, the EU average household price in the second half of 2025, according to Eurostat.
That gives 4 kWh × 200 days = 800 kWh a year, worth about €230. Your result depends on your location, panels, consumption and tariff.
Backup power during a power outage
In a power outage, the backup socket switches to battery power within 10 milliseconds and supplies up to 2,500 W to the devices plugged into it, such as a fridge, a router or a laptop. It does not power your home's wiring.
Smarter use of your tariff
AI mode plans when the battery charges and discharges, and works with most European electricity tariffs. If your tariff has cheaper hours, the battery charges from the grid then and supplies your home when power costs more.
Built to last
Lithium iron phosphate cells are rated for 10,000 cycles and a 15-year lifespan, with a 10-year warranty. With IP66 protection and a range of −20 °C to 55 °C, the battery stands indoors or outdoors.
Easy to set up
You connect the panels with standard solar connectors and plug the battery into a socket. At 50 kg, it takes two people to move. A qualified electrician installs the Smart Meter Gen 2 in your electrical panel. The Solarbank 4 Pro ships set to 800 W of output; according to Anker, more output needs a fixed connection installed by an electrician, where local rules allow it.

Frequently asked questions
Can I connect the solar panels I already have?
Usually, yes. The Anker Solarbank 4 Pro accepts panels with an open-circuit voltage between 16 V and 60 V, connected in parallel, with up to 1,250 W on each of its four inputs. Most residential panels fit. Send us your panel model and we check it before you order.
Do I need the Anker Smart Meter Gen 2?
Yes, if you want the Anker Solarbank 4 Pro to follow your home's consumption automatically. Without the meter, the battery cannot see what your home uses and runs on fixed schedules. The meter goes in your electrical panel, and a qualified electrician installs it.
Will the Solarbank 4 Pro power my home during a power outage?
The Anker Solarbank 4 Pro has a 2,500 W backup socket that switches to battery power within 10 milliseconds. It keeps the devices plugged into that socket running, such as a fridge, a router or a laptop. It does not power the lights and sockets wired into your home.
Do I need an electrician to install it?
You set up the Anker Solarbank 4 Pro yourself: connect the panels and plug it into a socket. A qualified electrician handles two tasks: installing the Smart Meter Gen 2 in your electrical panel, and any fixed connection for more than 800 W of output, where your local rules allow it.
