## How do I calculate my Genset size?

For all other motor and non-motor loads, multiply the current by the voltage for watts. Calculate total watts used by the largest motor and all remaining motor and non-motor loads and multiply by 1000 for kilowatts. Add 25 percent for reserve/surge capacity and size the generator accordingly.

## How do I calculate generator size per kwh?

Add up the Total Watts to determine how much power your home is likely to use during an outage. Multiply the Total Watts x 1000 to find kilowatts. Multiply kilowatts x 1.25 to add a margin of safety and for future power needs. This is the minimum Generator Capacity required for your home.

How do you calculate kVA for a generator?

The kW to kVA Formula:

1. Apparent power (kVA) x power factor (pf) = actual power (kW)
2. e.g. 100 kVA x 0.8 = 80 kW.
3. The formula for converting kW into kVA is:
4. Actual power (kW) / power factor (pf) = apparent power (kVA)
5. 1 ton = 200 BTU/minute.
6. 1 ton = 12,000 BTU/hour.
7. 1 ton = 3.517 kilowatts.

### How do you size a diesel generator?

Can I size a generator from my electric bill?

A much simpler way is to take your electrical power bill, divide the number of kilo-watt hours (kWH or KWH) consumed in a month by 720 (the number of hours in a 30 day month) and apply a “loading” factor of anywhere between 3 and 7 which takes into account the fact that there is not much electrical demand during the …
