Flex Adventures ST45 45L Dual Zone Fridge Freezer | Solar Ready | Bluetooth App | 12V/24V/240V

45 Litres. Dual Zone. Solar Ready.

The Flex Adventures ST45 is a versatile, mid-sized dual-zone fridge-freezer designed for overlanders who need simultaneous refrigeration and freezing in a compact, manageable footprint. With 45 litres split across two independently controlled zones, it runs a dedicated fridge and freezer at the same time — keeping your meat frozen and your drinks cold without compromise.

What sets the ST45 apart is its built-in solar charge controller, allowing you to connect a solar panel directly for fully off-grid operation without an additional regulator. Combined with Bluetooth App Control via the Flex Adventures App (iOS & Android), ECO/MAX cooling modes, and a 3-stage battery protection system, the ST45 is one of the most capable mid-sized fridges in the Flex range.
