Hi
tonight I will be running my soundsystem from a generator for the very first time. It is 3.5kva and I intend to power a proline 3000 running two punishers and a very very low watt top. The genny just has mains outlets but seen as this is my very first time doing such a thing, what should I know before plugging everything in?

I think generators usually have meters in them (amp & voltage) but if there aren't you need to know what you're doing.

We used to run radios, laptops and stuff off a generator in the army.. running out of gas is your problem number one, the fuel filter is a close second. Tripping a breaker (if it has one, although they usually do) is possible as well.

Noise is a problem too.. we generally solved this by placing the generator far enough and digging a hole for it, which is bad if it rains, as it may choke. We used to put a few pieces of firewood under it in case it does so there's time to take action if the hole starts filling with water (the crew running the generator would often improvise a makeshit cover for it too)

EDIT : depending on the generator it may have a spark plug/electric start.. just make sure it has nothing plugged into it when you power it as it may damage your equipment. As far as tractor generators go I have no experience with them.. sold one to a customer and seen a few though, ones that could power a complete farm during a blackout.

two things about the generator size. - if you push the 3000watt audio out you'll want around 4200 watts of electrical power to run that. 

Your generator gives KVA which isn't equal to watts unless you have a purely resistive load. But you have an amp with a switch mode power supply, which is a complex load,  So 3.5kva (assuming a power factor of around 0.7 is ~2400 ish watts available.

If the generator has circuit breakers then you may find (given the response time of an MCB.) that you stall the generator before popping a breaker, so if you have fuel and it appears to run fine with little load, that may be why (trying to draw too much power from it.)

(Actuall I might be wrong about it being SMPS, you probably know better than me about that.)

minimum 5Kva Diesel regulated set and a minimum 500W ballast load gets my vote...

i live on a boat, we have a diesel generator 3.5 kva..... they're loud, try and put a panel (or something) between you and it,  you'll be supprised what they wont power, voltage drops etc. makes our washing machine throw up error codes!!! but our 3k inverter on boat will power it with a 24v alternator behind it. be carefull about earthing. be carefull about your set too Exclamation
