The fall to reBulk looks like the transition to Vfloat [[electrical:solar:status#transitioning_to_float|described above]]. In both cases the controller makes no (or practically no) power until the lower setpoint is reached. | The fall to reBulk looks like the transition to Vfloat [[electrical:solar:status#transitioning_to_float|described above]].

| A constant cycling 14.4v->13.2v->14.4v might seem extreme but in practice there is little actual cycling occurring. A fully-charged 4S LFP with no loads will rest somewhere around **13.6v**. So for actual SoC changes we are talking about the difference between 13.6v and 13.2v. With significant loads applied 13.2v observed could mean SoC as high as 90% and with trivial loads as low as 70%.((with trivial loads there might be only 1 cycle a day since voltage would not fall to reBoost)) In normal use the real cycling might be 100%->85%-100% and the solar is helping carry the loads during charging periods. |
