Buy a $10 digital voltmeter (or borrow one) and check the voltages. You may find a substantial voltage drop in the PD wiring.
A gen is mostly good for about 90 percent SOC charge. Beyond that takes many additional hours of running. A 50-90 gen charge is common.
With the Trimetric you are far ahead of the game to determine your solar needs. If your SOC is 30 percent*160AH battery capacity for example =48Ah you need to return from solar *12V=576W for the day /5 hours of sun =120W of solar. Double it for contingency so about 200W of solar. Plug in your numbers.
