Cycle Charge Factor compares the amp-hours removed from the battery and those returned to the battery while charging. It displays the comparison as a percentage. This number can be compared against the programmed charge factor (see page 112) to judge battery charging efficiency.
My charge factor is set to 94% or something close to that. So how do you compare these numbers to judge efficiency? It says you can, but it doesn't explain how to compare them, or what is considered good versus bad. I thought this is the real-world recorded number of the Ah in and out, so it should be similar to my programmed charge factor. But it's not, it's very very different.
Cycle kWH Charge Efficiency compares the kilowatt-hours removed from the battery and those returned to the battery during all activity (such as float charging). It displays the comparison as a percentage. This number can be used to judge overall battery efficiency.
Again, how do you use this to judge efficiency? Is a high number good? My number is below 50% so that sounds very inefficient to me. My system seems to be running perfectly and we always have plenty of power. But these two numbers have always been a mystery to me.
