As home energy storage becomes more common, distributors and installers need a simple way to explain the difference between system formats. The right answer depends on available wall space, daily usage, expansion plans and whether the buyer wants a clean integrated appearance or a modular upgrade path.

Wall-mounted batteries

Wall-mounted LiFePO4 batteries are popular for residential projects where floor space is limited and the owner wants a neat installation. They are easier to position on a dedicated wall and are often selected for light-to-medium household storage loads.

Stacked modular systems

Stacked systems are attractive when expansion flexibility is important. Buyers can start with one battery block and add capacity later. This format is often preferred by households expecting future appliance growth or installers who want a cleaner modular look than rack cabinets.

Integrated inverter-battery machines

Integrated machines combine inverter and battery into one system package. This can reduce installation complexity and simplify product sourcing, especially for distributors who want an easy-to-present residential solution.

Questions buyers should ask

How many hours of backup are required, will the battery need to expand later, and should the inverter and battery be separate or integrated? These questions help filter product format before quotation.
