Yes, the gen set is in series and paralleling the output will give me 120vac at 2x the current. My concern is the 240vac avr, that can be set for 120vac, won't be able to supply the field voltage to get full output when set to 120vac. I guess I could measure the field voltage at full load to see...
Hello, I have a Stamford S0 series alternator head controlled by an AS540 avr that is currently set for 120/240vac. I would like to change the winding outputs to 120vac. I know how to change the wiring and set the jumper on the avr but I have a question about the maximum output power.

I wish I had a network analyzer...
I guess I will get a few of those caps and try them out. If I use my clamp-on amp meter on one of the legs of the cap, will I be able to tell if one value is better than another?
Are there any suggestions on how to solve this problem with my existing setup? How would I go about selecting a capacitor value that would filter out the noise and have a reasonably long life?
waross, I hear you about the AVR and this may be the problem but Outback has sold thousands of these inverters and only a very small percentage has had problems with generator charging. When I contacted them years ago they recommended the cap but could not provide me with a value and said start...
waross, I have looked into alternate charging systems. I would need a 24v 100a battery charger to replace my current charging requirements, lotsa bucks there. I can't run a DC gen because of the wire size and the distance plus I just got a new AC gen anyway.
I have thought about the AVR problem...
The generator is a new 8kw diesel. It has not been the first gen I've used here.
When the generator is on, it runs the house loads (by-passed) and the inverter charges the batteries. It is when the inverter is charging the batteries the problem happens. If I disable the chargers, the problem...

Yes solar, about 6kw worth. The generator is for cloudy days and it runs about 200 hours or so a year
OK here are some details you wanted:
A, 120vac to the inverter/charger (x2)
B,C,D, Lead acid battery @ 24vcd and 1700 amp hours
E, Max charging current for each inverter, ac input=20...
Hello all
I'm having a problem with a non-linear load driven with an AC generator.
This is an off-grid system with a generator used for charging batteries through an inverter. When the gen is charging the batteries, there is interference from the 20khz switching frequency of the inverter that...
ice: F1 and F2 are running half wave with the diode. The windings act real funny too. If I remember correctly, the battery winding puts out about 16-18 vac OC no load and when I run a 4kw load (with the AVR) that goes to around 22 vac. The field winding ends up providing around 12 vdc to the...
There was a 2 to 1 spade lug adapter on the AC terminal in question. It seems that they used that instead a terminal block for the wiring.
The windings off the neutral: The first winding goes to charge the starting battery and the second is for the field.
The zener is used as a surge...
iceworm: I noticed that too. On the gen it's wired the same way, it seems that they are only using one diode of the bridge. They use the same bridge throughout the gen. With the AVR in place, the bridge is just a backup.
