sola basic adjustment pot
Hi, Does anyone know where I can find the voltage adjustment for "cut in" on the Sola Basic 4000?

Almot and red31,
Thanks for the links!
The Sola Basic has three layers of boost and one of buck (135 volts)
110-->121 (nope wishful thinking)
100-->121 (nope wishful thinking)
90-->109 (don't know have never encountered voltage that low).
What I am finding is I'd prefer to have 112, 102, and 92.
The 110 does boost to 117, under load. I'm assuming the 121 is without a load. That's always suspect.
When I installed the Micro Air unit I kind of "shot myself in the foot", as the initial surge without the MA would cause the Sola Basic to go to voltage boost when the roof air started--and it would do so before the fan and compressor were even "up to speed". After the MA, with its "two step start up", was installed there was not enough voltage drop to cause the Sola to trigger a boost. That is one reason why I want to raise the "cut in" voltage on the Sola.
In the summer time I have seen 102 volts (under load) at a campground. But as it stands now the Sola, which I guesstimate raises voltage by 7 (under load) at the 110 volt boost level is not quite where I'd prefer to be. Voltage sags more than I'm comfortable with. If I can set it to boost at 102 instead of 100..... perhaps I'll be smiling.
That said I have used the Sola on 97 volts (under load) and it did enough boost to safely run the roof air. That was on a weak 15 amp plug at a rural Church. It is at least 150 feet from the plug to the breaker panel in the Church, and the Community is a long ways from the transformer, so unloaded voltage at the plug is a scant 100. The shore power breaker did eventually go into thermal overload. It took about an hour to do so.
I knew I was pushing the circuit hard as the kill-a-watt meter was making warning noises.
