However, the second that I begin to add any significant load (e.g. ceiling fan) the frequency drops to 49Hz sharply and then fluctuates between 49Hz and 54Hz. The voltage holds steady with absolutely no drop and the engine makes no noticeable difference in RPMs. Any thoughts?
On perhaps a related note, as soon as I switch to the Genset, one of my circuits that is an arc-fault breaker trips, not allowing the circuit to be powered. This did not happen with my previous generator using the same transfer switch.
As for the Arc-Fault problem, did your previous genset have a bonded neutral? The neutral part of the Arc-Fault breaker is an essential part of it's function.
AFCI
Many of the installation instructions warn about certain appliances that are problematic with AFCI's. Often mentioned are fans, toasters, and vacuum cleaners.
"The AFCI circuitry continuously monitors current flow through the AFCI."
If your genset is not maintaining constant RPM (dirt in carb, plugged Air Cleaner, fuel problems, etc) the AFCI may view the uneven current flow as unwanted arcing and shut down. It is only reliable if the supply of "current" is steady.
