I have an Entec West EW-4200-D 4.2 kW generator
. It starts and runs great, with a pretty steady 60 Hz output under various loads (drops maybe to 59.3 HZ fully loaded). The issue is the voltage. Under no load is at 109.5 volt, and if loaded up to 21 amp (out of 35 amp capacity) voltage drops to 104.3. Specified output is 120 VAC.
This is a huge issue as my battery
charger's DC output to the batteries is greatly reduced (like cut in half or worse) with these low voltages. The charger
wants to see 115 VAC or better for proper operation.
The manual says nothing about adjustment of voltage of the generator
. Getting info from factory is an issue as Entec was sold some time ago to Mastry Engine
Center, and no one there seems to know much about the Entec product (or at least no one I have talked to yet).
If anyone should happen to know the procedure for adjusting AC voltage output of the generator on these units, I would most appreciate your help.
