I assume the charge controller is MPPT. It likely has up to a 100 or 150VDC PV input. It's got a DC to DC converter. It will step down the PV voltage to the battery while upping the amps. Ultimately Watts in = Watts out - conversion & transmission losses.
Going with the higher voltage is better if you can do it, especially for a long power cable. It has less loss in heat and voltage drop. I think I have that same Renogy (Rover40). It can do higher voltages and keeps the current in lower but full current at 12v (14.6v) out to the lifepo4s.
I was one of the monitors of the KT5TX GOTA station at the KK5W Field Day site, and we heard one NTX station after another. We were STX on 40 meters which started slow at 1pm but started to pick up around 5pm. 73 KD5YOU
Typically vertically polarized antennas will pickup local noise sources far greater than horizontally polarized antennas. Did you test the Hexbeam noise level against your other antennas. Do you have access to a spectrum analyzer attached to a directional antenna to locate the noise sources?
That was great video. With that MPPT charge controller you need to put panels in series and make higher voltage. Look at spec on input voltage. right that max down. now read the back of panel. you want the open circuit voltage. this is the higher number. now add them together. if less than max input . hook them up. if to high voltage take one panel out. add them up again. MPPT charge controller for solar will take higher voltage and convert it to more amps into battery. Maxim Point Power Tracking. if RFI noise take a t 240-43 ferrite core wrap solar input cable pos and neg a few wrap's . do the same with the battery side as well. keeping ferrite close to charge controller as passable. Them snap ferrite work as well. use more than 1. use bigger Diameter one and do pos and neg lead at the same time. Most MPPT solar charge controllers make RFI noise. use ferrite in wires in and out. placing both pos and neg together. I have Victron and a few outers ferrite 240-43 cores worked well. same torrid used on many end fed half wave antenna's . 73's
Field Day is all about working through bad conditions so that we can operate during an emergency. You guys did, and had some fun as well. There's an "emergency communications team" near me that bagged on field day one year because rain was forecast. WTF? I guess there are no emergencies during bad weather.
Solar charge controller may handle all 8 panels in series. The open voltage of all the panels added together must be less than the maximum voltage of the charge controller. If, I assume, it is a MPPT charge controller then it will optimize amperage and voltage to your battery requirements, again assuming, you programmed the charge controller correctly.
Thanks for the video. What kind of mast / tower do you have your hexbeam on? I just bought a NA4RR hexbeam and am trying to find a suitable mast for it (can't really afford a tower, or the shipping of a tower).
Interesting. Maybe you guys need to get some high pass filters and cut out the power noise. Or maybe get a spectrum analyzer and see what noise there is and where and then make the appropriate changes. Monitoring that might help you guys characterize the noise. Otherwise, I like seeing you guys on the lease! Look real fun! At least you guys eat good.
Check the specs on your charge controller. Most modern charge controllers are looking for 35-150v on the input. This dictates a series configuration of your cells. They do this to reduce the I^2R loss in the cables.
The starlink may be inconsistant because its on the end of a 25-30 foot pole that is moving in the wind. My terrestrial internet uses an antenna that focuses the signal much like a laser. When I had it on a pole at a distance it would vary in signal especially when wind was blowing. Think of it, I bet the starlink is like that and its like your rifle, a tiny move of the barrel affects your point of impact of your bullet at a distance, same with your signal. The starlink is always trying to correct for that signal strength.

I liked the vlog style. It gives a good overall picture of your outing. Thanks for sharing.
Thanks
I had a blast on Field Day from a 4500’ mountain summit on the 26th.
That sounds fun
@@HamRadio2 about 1-1/2 hours west of Overland / where you were in October.
Mppt charge controller can take higher voltage from panels and charge a lower voltage battery
is the big generator grounded

Wow, not a mountain in sight!!!🤣
Nice.............
Jason there is a guy in Canada van city van life who live stream with his . He loves it
Thanks, I'll look that up. We're going to try that again this week

A Field Day without Machine Gun Mikey (k8MRD) ain't no Field Day. YFUG just said that. Happy monday & 73 💯🙋♂️👍

TeamReplay for the win
I hope your dxing is good stay safe and please stay cool

A little please copy action
Nice setup.
Our band conditions were not that great either.
