Is there any way to tell which models have the load delay/shedding and/or the Volt Guard?

I'm looking for a 120/240 unit in the 3500 watt range (rated) with a 120/240 switch and haven't been able to see from the manual or parts list any reference to Volt Guard.

I also recall reading that some units have a better THD rating than others. Is there some place where I can look this up?

To the best of my knowledge, Champion is the only Chinese manufacturer including the volt guard in their synchronous generators. An aftermarket volt guard unit named the "KillAVolt" is available from SuperGen Products. It plugs into one of the 120 volt outlets and provides over voltage protection for all outlets. You also keep access to the outlet used since the KillAVolt has a pass thru socket. I have one and they do work.

Again, to the best of my knowledge, the CPE46538 with remote electric start is the only Chinese synchronous genny with the load activation delay and load shed before shut down. Ironically, the features of the 46538 were the direct result of what was unanimously asked for by folks that frequented this forum thread. Without our input I doubt it would have ever been offered.

CPE is giving THD numbers higher than what I have measured on my unit. Interesting - it usually works the other way.

Why do you need 240 VAC? About the only item you can use it for in the USA is a small (1/2HP) shallow well pump. If that is your goal and the noise level is not of greater issue the new 41533 is a a 46538 on steroids. It has a 50 amp RV plug and all the safety features. It makes a great home back up unit when coupled with a transfer switch.

Yes, the CPE42412 is a "brush-less" unit - also known as a short shunt self exciting field generator. I know of no one that has worn out a brush set on an AVR equipped generator. But, I do keep a set in my spare parts box - just in case. IMHO, the 42512 is an amazing little workhorse of a genny.
