OK, it seems I was way off on the WH efficiency. Trimetric says 70 to 80%, not my guesstimate of 90%.
Trimetric gives a conservative 94% for AH efficiency. They do say it can be as high as 98% during absorption. Though I didn't state it, the 100% I was referring to is during absorption.
There you have it. No one should be referring to WH when discussing battery charging. It may make their mppt system look good, but meaningless to battery charging.
