Randy - Last question first: How come most generators don�t have a voltmeter? Because they're pretty much not required! By their design the output voltage on low end generators cannot be adjusted, except by changing engine RPM. And changing RPM also changes output frequency. So as long as the engine is running at design speed (3,600 RPM)- and the generator is working at all - voltage output should be to spec. (Would make more sense to stick an idiot light to indicate presence/absence of voltage and frequency meter to indicate when a generator is running at 60 hz.) ---- What size to get? If your pump is wired for 240 volts a 4,000 watt (continuous) generator should start it with no problem. If the pump's wired for 120 volts however, an 8 HP 4,000 watt genny would be be marginal. Trick then is to use the shortest and heaviest possible cord (#10 recommended) between the generator and the pump control box. --- Are cheap generators OK? From my experience, for occasional home emergency backup use the cheap generators are just fine. For home backup I've had a Tecumseh/Coleman 4 kw unit for 15 years. And I've had a 2,500 watt Briggs/Coleman at my camp even longer. Yeah they're not a Hondas. But I could have purchased FOUR Coleman 4 kw genny�s for what my neighbor paid for his equivalent Honda! For the 10 - 20 hours or so annually each usually runs, they all perform exactly the same. ---- Tip - Just keep oil in the engine, and drain the gas tank/carburetor before storing it away - a cheap genny should last you a long time...
