Power station for a fridge and freezer

The setup

The loads, with the goal of one full day without a recharge
Appliance	How many	Running	Energy a day
Refrigerator (modern, full size)	1	275 W	1.3 kWh a day × 24/24 h = 1,300 Wh
Upright freezer	1	300 W	1.2 kWh a day × 24/24 h = 1,200 Wh

Running, everything on at once: 275 + 300 = 575 W
Starting watts needed: 575 - 275 + 1,000 = 1,300 W
Watt hours a day: 1,300 + 1,200 = 2,500 Wh
Goal: one full day without a recharge (24 h)

What to know

Two cold appliances double the energy but not the start. The refrigerator uses 1.3 kWh a day and the upright freezer 1.2 kWh, 2,500 Wh together. The math counts one compressor starting while the other runs, as the calculator does: 575 W running and 1,300 W to start.

16 of the 54 stations are enough for a full day. The closest fit is the BLUETTI Elite 300 (3,014 Wh), with 24.6 h of this routine. 11 cannot power the pair, 11 of them on the start.

Food keeps longer in a freezer. Ready.gov puts a full freezer at about 48 hours with the door shut and a refrigerator at about four, so when the battery runs low, the refrigerator is the one to keep on.

An older refrigerator raises the daily energy, and the question below works it out. A chest freezer uses less than an upright one in the data, 0.8 kWh a day; the chest freezer setup runs one for two days.

Questions

What size power station do you need for a refrigerator and a freezer?

This setup uses 2,500 Wh a day. Lasting 24 hours takes 2,500 Wh usable, about 2,941 Wh of rated capacity at 85% efficiency. It also needs 575 W of continuous output and a surge rating of 1,300 W for the start.

Which is the smallest power station that is enough?

The BLUETTI Elite 300, at 3,014 Wh: 2,562 Wh usable gives 24.6 h of this routine. The ranking puts the smallest capacity first, then the lower price, then the lighter unit.

What changes with an older refrigerator?

With an older refrigerator (1990s to 2010) in place of a modern full size refrigerator, the setup uses 2,980 Wh a day and needs 575 W running and 1,300 W to start. 9 of the 54 power stations are enough for one full day without a recharge, against 16 for the setup above. The closest fit is the BLUETTI Elite 400 (3,840 Wh).
