How Many Watts Does a Refrigerator Use? Running, Surge & Daily kWh (2026)
How many watts a refrigerator uses: running watts, startup surge and daily kWh by fridge type, plus how to size solar, batteries or a generator to run one.
Keeping food cold is usually the largest continuous electrical load on an off-grid property, which makes efficiency worth more here than anywhere else on the site. These guides cover 12V compressor refrigerators and freezers that run straight from a battery bank, propane absorption units for properties without one, chest freezers, ice makers, and portable cooling that travels. We report real daily watt-hour consumption wherever it's published, because that number decides how much solar you need.
