≈ 0.6 days (24h/day) · Safe motor start buffer (70.4% margin).
full-size fridge running (240 W max) and start-up (1,200 W max) draw fit the Bluetti AC180's 1,800 W continuous / 2,700 W surge ratings.
ENERGY STAR top-freezer, doors kept closed (36% duty cycle, 40 W avg)
20–25 cu ft fridge at ~41% compressor duty cycle (65 W avg)
older or French-door unit in a warm kitchen at ~45% duty cycle with defrost (108 W avg)
≈ 0.6 days (24h/day)
System standby power: 15W (17.5% of total draw)
Provides 4× BS 1363 (230V) (120V 60Hz).
Pure sine wave inverter output. Safe for all standard household appliances.
Inductive motor/compressor load with 5× starting surge (motor inrush) (70.4% worst-case surge margin).
Wall AC fast charge at up to 1440W (45m to 80%, 78m to 100%).
Safe envelope verified: Starting surge (800W) remains comfortably below the 2700W surge trip line, with steady-state operation settling into the safe continuous zone at 160W.
About 13.5 hours on AC power, with the full-size fridge averaging 65 W (20–25 cu ft fridge at ~41% compressor duty cycle (65 W avg)). The Bluetti AC180 then draws about 86 W from its battery, including 15 W for the inverter itself. Best case: about 19.9 hours (ENERGY STAR top-freezer, doors kept closed (36% duty cycle, 40 W avg)). Worst case: about 8.6 hours (older or French-door unit in a warm kitchen at ~45% duty cycle with defrost (108 W avg)).
Yes. The full-size fridge's start-up peak of about 800 W (up to 1,200 W) fits within the Bluetti AC180's 2,700 W surge rating, with 56% headroom even in the worst case.
That simple division gives 17.7 hours, but the Bluetti AC180's inverter draws about 15 W whenever its AC outlets are on. At this light load that's 18% of everything the battery supplies, and inverter conversion losses take a further share. The idle figure comes from Bluetti.
On wall power: about 45 minutes to 80% and 78 minutes to full (Bluetti figures). With its maximum 500 W of solar input connected, expect about 400 W in full sun, so a full recharge takes roughly 3 hours of full sun, so it can refill in a single day with 4 peak sun hours.
