Help:Electrical/battery charging issues

[nsdtr3]

We have a 2017 Keystone Montana 3720RL and on our first trip. Our RV has Go Power Solar panels 2 x 160W and a propane 6500 Cummins generator with a 2800 magnum inverter/charger. The first inverter charger was from go-power but the batteries lost charge or weren't charging so they replaced with the magnum. (told us the generator wasn't compatible with the go-power software). When we left for our trip the batteries were too low for us to use the jacks so we used jumper cables to add power the batteries and get the generator to turn on....okay we get going to our camping site 4 hours away. Hook up the 30 amp service and all seems okay, BUT a few hours later we hear a beeping sound from the go-power panel. Decide to unplug the 30 amp power cord since batteries should be charged up. Wake up this morning and low battery power :-( Plugged back into the 30 amp service. Pictures are of our panels...... Not sure what to do except not happy with the installation of these products....Accepting suggestions from you experienced RV'ers. Thanks in advance from a newbie who's going to figure this out while on our 2 week vacation. We have 4 x 6 volt house batteries....
