LVM15 Mobile vs Stackable Version: Which is the right choice for your installation?
The choice between the LVM15 Mobile version and the Top Energy Stackable version depends mainly on your environment and your usage.
| Criteria | LVM15 Mobile model | Stackable Version |
| Installation | Ready-to-use solution (Plug & Play). No complex assembly or internal wiring required on delivery. | Requires modules to be stacked sequentially and inter-battery connection. |
| Maximum | Maximum. The unit can be easily moved for maintenance operations or to reorganise the space. | Fixed without a base. Solution designed for permanent and definitive installation in a dedicated plant room. With the optional base, this battery also becomes mobile. |
| Footprint | Compact vertical tower format with castors. Optimises floor space whilst remaining self-contained. | Scalable modular design. The total height varies depending on the number of storage modules added. |
| Ideal use | Residential properties, offices, data centres or homes requiring simplified maintenance and mobility. | Fixed residential installations, dedicated premises. |
The verdict: Choose the LVM15 Mobile if you’re looking for immediate installation without assembly and the ability to move your power source. Opt for the Stackable version for a more aesthetically integrated, less mobile solution and slightly higher capacity per module.
