When we use our generator, I always keep a light on which allows me to gauge how the load sharing is doing. If the new load makes the light dim, I shed other load immediately. Things like the well get solo performances. You can also hear it in how hard the generator is working. It won't take long to figure out what keeps it happy. The other thing to remember is that the lighter the load, the longer the gas will last.
But after writing this it occurs to me that I should just plug my multi meter into an outlet to keep an eye on the voltage level. Duh.
