Hi everyone,

The MPPT in float is charging the battery with 9.3A. How is it possible ? It is a 100/30 smartsolar. He is connected to 2 175W pannels en series with battery voltage of 12V.

Here are some more information :

It's quite possible for a battery to accept that much current in float if the switch from absorption to float occurred too early. It's also possible you have some loads drawing from the battery, in which case the MPPT is powering them (and that output will show as current going to the battery on the MPPT display).
