What this job asks of a station

AC outputat least 1,800 W, to start a fridge and run a heat source. 50 stations pass.
UPS switchover20 ms or less where the maker lists one. 67 stations pass.
Capacityat least 2,000 Wh, or expandable past 4,000 Wh. 38 stations pass.
Why these limits

Three limits take the field from 81 stations to 31 for home backup, and capacity is the tightest: 38 stations reach it, against 50 on AC output and 67 on switchover. The bars are 1,800 W of AC, a listed switchover of 20 ms or less where the maker gives one, and either 2,000 Wh or an expandable system past 4,000 Wh. The 31 that pass run from 1,024 Wh to 12,288 Wh, with a median of 2,560 Wh. Two near misses show where the lines fall. The EcoFlow DELTA Pro has 3,600 Wh and 3,600 W but lists 30 ms, and the Jackery Explorer 1500 v2 has 2,000 W but only 1,536 Wh.

FAQ

How much AC output does the home backup limit ask for?

At least 1,800 W, enough to start a refrigerator and run a heat source. In all, 50 of the 81 stations reach that figure.

Of the passing stations shown first, which is lightest?

The BLUETTI Elite 300 at 57.98 lb, with 3,014.4 Wh and 2,400 W of AC. The Jackery HomePower 3000 follows at 59.52 lb with 3,072 Wh and 3,600 W. Neither can be expanded.

Why is the EcoFlow DELTA Pro not on the passing list?

It lists a 30 ms switchover, over the 20 ms limit. Its 3,600 Wh, 3,600 W and 10,800 Wh maximum system all clear the other bars.

Which of these list split-phase output?

The EcoFlow DELTA Pro Ultra X, DELTA Pro Ultra and DELTA Pro 3, the Jackery Explorer 5000 Plus and HomePower 3600 Pro Max, and the Anker SOLIX F3800 and F3800 Plus list yes. The Jackery HomePower 3600 Plus lists it with a kit. How any station connects to a home panel is a question for the maker and an electrician.
