Backup power for a home office
A home office is mostly clean electronic load with little surge — an inverter generator or a modest battery keeps you working through an outage quietly.
Running
2,300W
Peak surge
2,300W
Recommend
3,000W
These are mostly steady loads with little startup surge. Sizing for the running total plus that single largest surge — not the sum of every surge — gives a realistic 3,000W (3.0kW) recommendation.
Typical loads for a home office
| Load | Running | Starting |
|---|---|---|
| Computer + monitor | 300W | 300W |
| Household lights (LED) | 200W | 200W |
| TV + WiFi router | 200W | 200W |
| Phone/laptop charging | 100W | 100W |
| Space heater | 1500W | 1500W |

Common questions
What size generator do I need for a home office?
For this typical load set, about a 3,000W (3.0kW) class covers it — that's 2,300W running plus the largest startup surge (from the no motor load), with a 20% margin.
Can I run more than this?
Yes — this is a representative set. Add or remove loads in the load sizer to match your exact situation and get an updated number.
