Good to know
Choose a compressor fridge for home-style cooling and freezing on 12V or 24V, ideal with solar. Choose a 3-way gas fridge for silent running on LPG. See our gas fridges.
It depends on size and conditions. For example, the 86L wheel arch fridge averages around 0.36kWh a day, the 175L built-in around 550Wh a day and the 145L slimline around 600Wh a day.
Several models run on 240V AC as well, including the 220L, 270L and 140L fridge freezers, and others come with a 240V adapter. Check each product page.
Match your battery system. Many of our fridges select 12V or 24V automatically. The 300L model is 24V only, and the 86L wheel arch and 175L built-in are 12V.
