I tried asking a similar question a few months ago - 200 views and no answers!! So I'll have another go.
I need to buy a biggish generator 4,000W - 5,000W to operate tools while building but also as a backup generator and battery charger for the intended off grid solar set up when the build is finished.
Can anyone tell me if I need an inverter generator or will a regular one suffice? (The inverters are a LOT more expensive!!)
What are the primary benefits of an inverter generator?

The inverter generators have a more pure sine wave. Basically the power is cleaner and more stable.
With a generator the power is generated by a motor spinning at a fixed RPM. If that speed fluctuates the power quality also fluctuates.
With a generator inverter, the first part still happens, but the power generated is DC which is fed into a Inverter which converts it to AC. The electronics in the Inverter part smoothen the power and keep it at a constant value.
If you plan on using it to power computers and electronics in the long term I would be going for the Inverter Generator. If it was just for power tools or battery charging only, generator only would be fine.

Thanks Charger for your response (and others for links.) It made my decision easier - I really only need a regular generator as it will be used primarily for running power tools while building and when my solar (off grid) system is in place I believe it has its own type of inverter so the generator only needs to charge the battery bank when it is low on power.

I have two of these at work, they are both about 9 years old now and have been tough and reliable for a reasonable price.

I'm also looking for a generator about that size for long term power backup at home. I would love one of these in the link below, but I priced them up and it was quite expensive. I can't remember exactly how much, but enough to scare me off

The other one I am looking at is from this mob who have just popped up in Perth. Well priced, but you he what you pay for with cheap Chinese gear. Doubt it would last 7+ years.
