Scenario
Getting through a home power outage
When the grid goes down, most people want two things first: to stay reachable and to keep working. A router and a laptop are small loads, but over a long outage the inverter's own idle draw adds up to a big share of the total. The calculator below starts from that kit over a two-day outage, so you can see how far a given station gets.

How long some stations last
Typical estimate on AC at about 30 W on average, a Wi-Fi router all day plus a laptop for eight hours, from each published capacity and the labelled assumptions.
| Station | Capacity | Typical runtime |
|---|---|---|
  DELTA 3 Plus | 1,024 Wh | 20 h 43 min |
  Explorer 1000 v2 | 1,070 Wh | 21 h 39 min |
  AC180 | 1,152 Wh | 23 h 18 min |
  SOLIX C1000 | 1,056 Wh | 21 h 22 min |
 DELTA 2 Max | 2,048 Wh | 41 h 26 min |
 Explorer 2000 v2 | 2,042 Wh | 41 h 19 min |
  Yeti 1500 (2026) | 1,505 Wh | 30 h 27 min |
 SOLIX F3800 | 3,840 Wh | 77 h 42 min |

Start with what you can't go without
List the devices you would actually plug in, and for how many hours a day. A router runs around the clock; a laptop mostly during the working day. Daily energy, not peak watts, decides how many days a battery lasts, so hours matter as much as the device itself.
Bigger appliances such as fridges, sump pumps and space heaters change the picture. Their watts vary widely between models, so they are not in the calculator until we have a published source for a realistic range. Check the label on your own appliance before you plan around it.
Days, then solar
If the outage could last longer than the battery, solar is what keeps you going. The size calculator adds panels and sun hours to a multi-day plan, and the solar calculator shows how long a refill takes on a given station.
