The Solarbank 4 E5000 Pro in a few words
With the Solarbank 4 E5000 Pro, Anker SOLIX offers a battery that sits at the heart of a home photovoltaic installation. Its LiFePO4 cells provide a capacity of 5,024 Wh, and its MPPT inputs accept a voltage range of 16-50 VDC. The figure supplied for input current per MPPT is “1,250x 4 / 5000 W”, which we reproduce as given; the manufacturer’s manual will explain how to interpret it for your panel array.
What the MPPT inputs allow
An MPPT controller continuously adjusts the operating point of the panels to get the most from changing sunshine. Here, several inputs are mentioned, which is useful for a roof with different orientations or a pergola with a few extra modules. Before buying panels, check that their voltage stays within the 16-50 VDC range.
Family home
The day’s production charges the reserve, and the evening benefits. This is a common way of working for anyone who wants to make better use of the energy from their own modules.
Professional activity
A guesthouse, a practice or a small workshop can consider it too. Have the sizing validated by an installer, who will take your opening hours and your loads into account.
Construction
The housing is rated IP66 and withstands a stated range of -20 to 55 °C (the unit is not specified in the data; consult the manual). It measures 460 × 305 × 355mm and weighs 50 kg, which calls for handling by several people and a robust support. Communication is by Bluetooth and Wi-Fi (2.4 GHz): if your router broadcasts only on 5 GHz, plan a solution before configuring the unit.
Installation plan
- Choose a wall or slab able to carry 50 kg permanently.
- Measure the route of the solar cables and check they do not exceed the useful length.
- Entrust the connection of the panels and the link to the household network to a qualified professional.
- Once everything is de-energised, follow the manual for commissioning and pairing with the app.
What sets it apart
The three strengths emerging from the data are the 5,024 Wh capacity, the IP66 protection and the 16-50 VDC MPPT range. They describe a unit built to receive several strings of panels and to stay outdoors.

Safety instructions
The direct voltage produced by panels exposed to the sun can be dangerous even when the grid is off; never handle the solar connectors without knowing the subject. Respect the 16-50 VDC range, do not open the housing and keep any ventilation areas clear. In case of smoke, excessive heat or deformation, switch the installation off and call a specialist.
Maintenance and idle time
Wipe the housing with a damp cloth, with no solvent, and regularly check the connectors, the cable glands and the mounting. If the installation stays off, follow the manufacturer’s indications on the charge level to keep.
