Hello everyone
Our system consists of Classic 250, bergey xl.1 and ballast resistors which we used as a load where we throw extra power when battery is fully charged. We use aux1 on in diversion mode to switch power to ballast resistors through teledyne SSR when battery voltage passed setpoint (high voltage level). Is classic go to resting mode when power from turbine go to ballast resistors? If classic will be in resting it give aux 1 off in teledyne when battery voltage pass setpoint ( low voltage level), does it? Or we should use insomnia mode?
Sorry for my English.
Can you better explain how the teledyne and resistors are wired? Maybe even a diagram?
Does it more correct to use AUX2 instead AUX1? I guess that switch to heating load with SSR can damage or flame wind turbine's stator. Should we use PWM to switch to heating load more softly?
Thank you for answering, Ryan.
Yamal, I am not exactly sure what the problem is but your wiring diagram looks good and correct.
I would try Aux 2 if you are not using it though. If using Clipper Control mode,
make sure it is set to AC mode.
This ~may~ help your resting due to Aux 1 not being PWM... Aux 2 uses a PWM method
to drive your SSR that ~should~ make things run a bit smoother and possibly help keep the
Classic from Resting so much.
Insomnia may also help but the Classic output power must be low (less than 20 watts) for at least
90 seconds before it goes to Resting again so I am not sure why Aux 1 would cause this.
It may also be that Aux 1 is keeping the turbine loaded for too long of time or the Aux 1 high and
low voltages may be too wide.
What is the value of the resistors?
Thank you, Bob. We would try your advice with AUX2.
Ryan, we use 2 Ohm, 420Wt.
I am wondering about the effect of the auxiliary contacts SA on the SSR. It would seem to me that shutting off the input to the Classic would make it go to resting mode. Does the aux1 and aux2 modes continue to function when Classic is resting? I may be totally wrong about this but I would be tempted to have the input connected to the Classic at all times to keep the Classic "awake" and not in resting mode, that providing that the input voltage to the Classic would never be allowed to exceed the input limit of the Classic.
That said I have never done any work with a Classic powered by a wind generator.
I can see where contacts SA will protect the Classic from excessive voltage but can the Classic still function in resting?

TD, not sure what "SA" is (I probably do but can't place it at the moment)...
The Classic's AUX output should work any time, even when it is resting.

Thanks for that clarification, Thinking about it , of course aux would be active at all times or WBjr. /Classic could not record that data when resting.
In the diagram that yamal posted contacts SA are wired between the DC output of the diode bridge and the input of the Classic. They would shut off all input to the Classic when the SSR is triggered by aux 1 or 2. So if Aux2 PWM mode is used then the input of the Classic would be turned on and off at the PWM switching rate. My thoughts on that is this going to confuse the Classic? Switching spikes?

SA appears in his diagram as a DP relay feeding the PV + - to The Classic.

TomW,
My reading if the schematic seems to indicate that these contacts are auxiliary contacts on the SSR but as I have not had a lot of experience with them , I do not know if they do have auxiliary contacts or is this a separate relay? Controlled by what?

I am not sure what triggers it or if it is a separate "relay" the schematic is not very clear what is going on there? Is it switching the PV in to some other device / circuit, etc? Appears the active contacts in the drawing say L1 and L2 which may be feeding that resistor load? Hard to tell from the drawing if that is a connection back to the L1 and L2 of the Bergey? Or unused and it merely switches off the PV in.

Oh, OK. THAT SA ! It looked to me like a simple manual disconnect that you would want to have.
That should be fine. I don't know of any aux contacts on an SSR, especially a Teledyne 3-phase triac SSR.
I thought that is what he was using ?
That is right, Bob. SA is using for manual disconnect input voltage to Classic.
AUX 2 give control voltage that goes to SSR coil. After that SSR contacts become closed and bergey power goes to load resistors.
