Collection: Stacked Lithium Battery

Stacked lithium batteries let you build capacity in modules that clip or stack together, making them popular for homes and small businesses that may expand over time. The range includes 21 models split into two families: a low-voltage 51.2 V line at 10.24 kWh, 15.36 kWh, and 20.48 kWh, and a high-voltage 192 V to 480 V line at 9.6 kWh, 14.4 kWh, 19.2 kWh, and 24 kWh. Low-voltage stacks suit standard 48 V hybrid inverters and are easier for small installers to handle; high-voltage stacks reduce current and cable losses for larger residential or light-commercial loads. All units are IP65, so outdoor installation under a canopy or in a garage is generally acceptable. Each low-voltage module adds roughly 50 kg, while the base unit is about 14 kg; high-voltage modules start around 48–49 kg per block. Cycle life is rated at 6,000 cycles at 70 % SOH. When sizing, pick the inverter first, because high-voltage and low-voltage stacks are not interchangeable; then choose the module count that meets your backup or self-consumption target.

Modularity is the main reason installers choose stacked systems. You can start with two modules and add more as the household’s energy needs grow or as the budget allows. Make sure the base module is installed on a rigid, level floor; stacking modules on uneven surfaces can stress the locking mechanism. Cable routing between modules is usually plug-and-play, but the inter-module connectors must click fully into place to avoid resistance and heat. High-voltage stacks require more safety training than low-voltage stacks, so factor installer certification into the project cost. In commercial applications, stacked systems can serve as small UPS banks for server rooms or backup power for point-of-sale systems.
