Home backup guide
Decide whether you need a few essential appliances, a larger expandable backup base, or documented household-circuit capability. These are different levels of outage protection.

Why choose it Every core home-backup dimension documented in one unit: 4,096 Wh, 4,000 W continuous, single-unit 240 V split-phase, native TT-30, expansion to 12,288 Wh.
Watch out for 113.5 lb - a permanent placement rather than something you move between rooms.
Why choose it Documented single-unit 240 V split-phase output with 6,000 W continuous and expansion to 26,880 Wh.
Watch out for 132.3 lb; not a unit you relocate once placed.
Why choose it 5,040 Wh base documented to 30,240 Wh with 7,200 W continuous - the largest documented expansion ceiling on this page.
Watch out for 134.5 lb base unit and integration hardware is a separate decision; no TT-30 outlet is documented for it.
Why choose it 3,072 Wh at 3,600 W continuous with expansion to 11,000 Wh.
Watch out for 240 V capability is not documented for this unit - do not assume it can feed 240 V circuits.
Why choose it 2,042 Wh / 3,000 W expanding to 12,256.8 Wh - mid-size entry into real battery-backed uptime.
Watch out for No documented 240 V; UPS switch time is not documented despite rated support.
Why choose it 3,000 W continuous from a 2,048 Wh / 48.7 lb body with expansion to 10,000 Wh.
Watch out for Max solar input is not documented, limiting multi-day outage recharge planning.
Why choose it 2,048 Wh / 2,400 W expanding to 12,288 Wh with a native TT-30 outlet at the lower end of this set.
Watch out for 62.4 lb and no documented 240 V - this is 120 V appliance backup, not circuit backup.
Why choose it 3,072 Wh / 3,600 W with documented UPS/EPS support at a 20 ms switch time - connected electronics see a brief blip rather than a restart.
Watch out for Not expandable, and no documented 240 V - runtime and circuit scope are both fixed.

Do not assume a high-output station can supply 240 V circuits. Transfer-switch and integration compatibility must also be verified separately.
A large expandable station can support more loads, but it does not become a permanently installed whole-home battery without the required documented system design.
Account for startup demand, actual energy use and the station’s documented switchover behavior. Unknown switch behavior is not a promised UPS function.
FAQ
Most are best treated as selected-load backup unless household-circuit integration is explicitly documented.
Add continuous and startup demand for the exact appliances you plan to connect.
Only for loads or circuits that require it; many essentials are 120 V.
Only with documented compatible equipment and qualified installation where required.
No. Portable and installed whole-home systems have different integration requirements.
Duration depends on actual load energy use and available watt-hours.
