Goal Zero, Yeti 1500x

[yosemite]

new to soalr and got the yeti 1500x with 2 x boulder 200 panels. the output from each boulder 200 is 149 watts. i added a renogy 100 watt and by its self is putting out 89 watts to the yeti. when all hooked together it is putting out 341 watts. these are hooked together with 4 hpp connector(14 gauge?) and then through the gz 30 hpp cord (12gauge). this is miday full sun in central ca on 9/24/22

wondering where the bottle neck is, should i expect more wattage? maybe i should have bought 6 renogy panels for almost the price of 1 boulder 200.
