Above figures are indicitaive only. You must check your own equipment to ascertain your requirements.
A generator that is rated as 1kVa, can produce a maximum of 1,000 watts for a very short time (a few seconds).
It can only produce 80% of this figure for long periods of time, so a 1kVa generator is continuously rated at 800w watts. |
