An AC-coupled storage unit
Jackery’s SolarVault 3 Pro Max AC plugs into a 230 V outlet and acts as an energy reservoir for the home. In this bundle the 2520 Wh main unit is joined by two BP2500 batteries, bringing the bundle capacity to 7.56 kWh. The photovoltaic input appears as a simple dash in the data sheet, so this model is best understood as a battery tied to the household alternating-current circuit rather than as a solar panel controller.
Who can benefit?
A household that already generates solar power, or simply wants to shift its consumption in time, will find a compact foundation here. A small shop, a practice or a workshop can also use it to smooth daytime demand. In every case, assess your consumption profile before sizing the system: usable capacity depends on your appliances and your schedule.
Construction and protections
A monitored LiFePO4 chemistry
The battery is LiFePO4. It comes with multi-layer BMS protection, terminal temperature detection and aerosol fire suppression. These features are listed by the manufacturer; for how they work in detail, read the manual.
Housing and dimensions
The main unit measures 485 x 248 x 282 mm and weighs 25.5 kg. Its IP65 rating protects it against dust and water jets, which suggests a sheltered but unheated location such as a garage or utility room. The noise level is listed as ＜30.
Setting it up
