I have a MPPT 150/35 that was recently replaced by my RV manufacture while in for warrantee work. When they installed the MPPT 150/35 they connected the solar to the battery input and the battery to the solar input. It ran like that for a least 15 minute until I said the battery voltage is way too high. The then corrected it. Since then my display only shows it in bulk even when the battery voltage is over 15 volts. The setting 02 BATERY VOLTAGE indicates 24 Volts. If I would use the factory defaults would this correct all the setting that could be wrong during initial installation. I read that it determines if voltage initially and will not change automatically after that.
