A solar battery with four independent inputs
The Solarbank 3 E2700 Pro from the Anker Solix range stands out first through its input architecture: four photovoltaic inputs, each with its own maximum power point tracker (MPPT). Each string of panels therefore works at its own voltage, which is useful when orientations or shading differ from one roof section to another. This set shows a power of 2.4 kW and a capacity of 5.4 kWh.
Where and how to use it
The device stores solar production so that it is available when consumption rises. The stated connection method is plug and play, through a 230V wall socket and an Anker smart meter. It suits an apartment with balcony panels as well as a house whose roof has several slopes.
Homeowners
A modest installation can start with the unit alone, then grow with expansion batteries.
Professionals
Installers will appreciate being able to split panel strings over several inputs and to document each of them using the voltage and current limits.
Understanding the electrical limits
The MPPT voltage range runs from 16 to 60V on inputs PV1 to PV4. Each accepts at most 32A (40A Isc) and 900W. The photovoltaic input reaches 1800W maximum with the main unit, and 3600W maximum with a BP2700 expansion battery. Check the open-circuit voltage and short-circuit current of your panels carefully before any connection.
Setting up
Place the device on a stable surface, protected from impacts. Its housing measures 460 x 254 x 279 mm and weighs 29.2 kg, so it is best to get help moving it. It is rated for an operating altitude of 4000m and a temperature range of −20 °C to +55 °C. The Wi-Fi connection allows monitoring by app; detailed settings are in the manual. A qualified electrician should handle the links to the panel board and to the panels.
Strengths
- Four independent MPPT inputs for complex roofs.
- Starting capacity of 2688Wh, expandable with the expansion battery models specified.
- Weather resistance with the IP65 rating.

Safety
Never connect panels whose voltage or current exceeds the limits above. Use suitable cables and connectors, without twisting or straining them. Keep the vents clear and do not open the housing. If in doubt, ask a professional for advice.
Maintenance
Clean the outside with a dry or barely damp cloth, never with a pressure jet of water. Check the connectors from time to time. Before a long period without use, follow the charging recommendations in the manufacturer’s manual.
