I've installed the following PV/solar system on and in a shed: Four RS-M100 Rich Solar Panels, roof-mounted; Jarxioke 4000 Watt Pure Sine Wave Inverter; Two Eco-Worthy LiFePO4 12.8V 100Ah; 60A MPPT OEM Solar Charge Controller.
Solar panels are 100W, 18.6V (Vmp), 5.38A (Imp). I originally wired the panels in Series, and outputs were as expected: Volts up to about 80, Amps were appropriate. I rewired the panels in Parallel to see the difference. In Parallel, Volts are as expected, about 18. However, Amps are not adding up, but remain as if the panels are wired in Series. I measured the Amps directly from the panels before any current etc. reached the Charge Controller, and the Amps remain as if from a single panel, not additive of all four panels. I used 10 AWG copper wire to wire the panels.
My question: what are the possible reasons that the AWG is not additive? And thanks for any help.
