So this may or may not be seen as a beginner question, but I have a feeling I'm trying to debunk a myth with MPPTs. My MPPT is a Li-time 30A controller, and it states that the MPPT must be connected to a battery before connecting it to solar. I have watched a couple videos now that also say that if one does not connect a battery before connecting solar, that it will damage the MPPT. Here's my issue. If my battery becomes fully charged, then it effectively disconnects from the MPPT, meaning that it is just solar connected to the MPPT. Ok, so maybe since the MPPT has control over that disconnecting action, its not a big deal. But what if the battery performs the disconnection? Say the battery has cold temperature protection, it gets too cold, and it shuts off at the BMS. Then you suddenly have the same situation where the MPPT is connected to solar but not to the battery. To clear up one more thing, the MPPT manual specifically says to cover the solar array in a blanket before connecting, which would remove the possibility of creating a small arc during the instant of connection. So, is there a technical engineering reason why a battery should be connected to an MPPT before connecting a solar panel, or is this just a myth probably devised for the protection of individuals working with actively-generating solar panels? Assume there is no other load connected to the MPPT or to the battery.
