Battery Applications & Installation
5kWh · Wall-mounted Home Storage
The 5kWh specification table lists wall-mounted installation. Its feature page also supports floor-standing use for indoor residential energy storage.
16kWh · Indoor Home Energy Storage
The 16kWh model supports home energy storage and is specified as stackable, with expansion up to 32 modules per string. Stacking arrangement and hardware must follow the installation manual.
Installation conditions
Both batteries carry IP21 protection and use natural convection cooling. Charge: 0 ~ 55 °C; discharge: -20 ~ 55 °C. Power derating is required above 2000m. The 16kWh datasheet does not specify wall mounting. Mounting, stacking, wiring and clearances must be confirmed from the installation manual.
