here is another tidbit of information: Voltage is pushed from the source (potential, pressure) and you don't want to exceed the capacity of the load device (charge controller) Current (amps) is pulled from the load (draw) and you don't want to exceed the capacity of the source or the connections. Power will be limited by the charge controller, and you'll have the 500 watts longer through the day, and for some cloudy conditions (shading) with the little extra solar panel capability that you installed.
what are you powering with your limited battery bank? that's your weakest link right now. is it really only 2 kilowatt hours? or the 10% - 90% ? and its low voltage input limitation is holding your panels under water. the solar panels and the entire system works better with higher voltage. if electrons are like water, then Voltage is the pressure, and the Amperage is the flow. Volts X Amps = Watts., . , ,, watters flow low voltage requires more amps so you need much thicker wire, you're also getting more HEAT which is hard on the circuit boards. i advise you to go back to the drawing board and set up a 48v battery, inverter, MPPT charger(Maximum Power Point Tracking) if you plan to do more than charging phones and led lights, get a battery that has at least 10 kilowatt hours, 48 volts. like Eve 280 amp hour Lithium Iron Phosphate prismatic cells. then you can get back to optimizing the solar panels after
I'm using two Ecoflow Delta 2s right now. The max solar input is 500 watts and now I'm hitting that mark. They are 1024 ah each. They are currently running my refrigerator, freezer, big screen, wifi, and some room lights.
@@larvae91 1024 ah at what voltage? that way you can calculate watt hours, 12v X 1024 ah = 12,288 watt hours or 48v X 1024 ah = 49,152 watt hours. my battery made of 16, 3.2 volt 280 ah Eve cells wired in series for a battery bank with 51.2 volts X 280 amp hours = 14,336 watt hours
@@larvae91 my mini fridge with freezer top compartment uses about 850 watt hours daily, hardly noticeable. but my u-shaped split ac window unit cooling a 350 cubic foot space, uses about 3000 watt hours daily, and thats 77 degrees.... but its been pretty hot out. im trying to get a good deal on some Bi-facial solar panels, i wish i got those type originally. off grid right now and i use an inverter generator to charge up the battery here and there, especially since its been cloudy for weeks.. 🤬 atleast its the most efficient way to run a generator as you can set the ideal load / RPM which is about 60% its rated running watts. and in the future i will make a gasifier so i can run my generator with fire wood / woodgas

moar is better!
thanks for the challenge
