While it is unlikely that I will ever need to use the generator input on my 18Kpv, I do have a generator...although it is a small 2kW 120v model. Is the generator input meant only for use with a 240v generator or would it also work with a 120v model? I can't seem to find this information anywhere.

The generator input for the 18kPV requires 120/240VAC. For more details on the generator requirements, please refer to page 22 of the 18kPV manual.

Thank you.

Thank you.
I had the exact same question as you, and got the same answer. However, I also received some advice to look at the EG4 "Chargeverter." It's a relatively inexpensive 48V charger that can take 120VAC or 240VAC input. On 120VAC it's limited to charging at 45 amps, but that's still more power than the 2kW generator you (and I) want to use in this scenario.
So, I bought a Chargeverter along with my 18Kpv and four LL-S batteries. I haven't tested it yet - I'm just now finishing my system setup. I have the Chargeverter outputs connected to the EG4 rack bus. Once I finish all my other tests on this backup system, testing that I can charge from a generator is one of the last tests I'll do.

This is just poor documentation. Something I have become very used to with EG4. The equipment is good the documentation just plain sucks as it was written by engineers and they are engineers not writers.
The manual says "120/240". So what does that actually mean in real world terms? Does it take both types of inputs or is this a designation for split phase with 120 per leg? Beats me. Really unclear. All these people on the forum are trying to do is decipher this cryptic nonsense that is passed off as a manual.

agreed, if anything the table of contents should include a page listing definitions such as 120/240 meaning 2 phase 240VAC or something else.
Sounds like someone would need a Honda EU2000i plus the EU2000i companion to get 240V or a better choice might be as @JLankford mentioned a 120VAC to 48VDC charger.
