Bar graph!
Here is a graph covering 10 days of summarized data. The bars represent hours of duration for the MS MPPT 15L controller states; Night, Bulk, Abs, Float, and Equalize. The graph data is extracted from the controller by a Raspberry Pi 3 B by using the MODBUS protocol.
July 5: You see some of the 28 day equalization. I don't know why it was only 31 min.
July 6: You see the tall Bulk bar. I ran the 5000W A/C for 4.5 hours between 1PM and 5:30PM which caused the controller to stay in Bulk all day. The bank was under 12V overnight(not shown).
July 7: You don't see any tall charge bars. That is because I ran the 50A inverter/charger for 3.5 hours to expedite the Bulk charging. That is what I would normally do if running the genny due to a low morning Volts(not shown). The controller doesn't record the 50A. Also there is no Float bar because the controller is set to skip float when Volts have been low.
July 12: You see a tall Night bar. I covered the panels with a blanket for 3 hours between 8 and 11:30AM. Extended Night hours is what would happen during a storm. The controller handled this well.
July 13: All seems to be back to normal.
