Voltage drop under load

The voltage you see when a battery is under (heavy) load has no relation to the voltage vs state of charge curve. In the latter, the voltage refers to the "resting" voltage - no charging or discharging for a few hours. It is perfectly normal/acceptable for the battery voltage to sag by 0.5 to 0.7 V under heavy load.

voltage drop from panels to SCC

The PV input voltage is acceptable, it is well below the Max PV Input Voltage of the solar charge controller. If the PV cables are measuring 115 volts before being inserted into the solar charge controller and then those same cables are measuring only 35 volts after being connected to the solar charge controller, then something is wrong.
