So my question is, will this distance present a problem? What voltage drop will I experience with this distance and would it be better to convert it to AC at the panels or at the house?

In my opinion, the ideal would be to prepare a room near the solar panels to place the inverter, battery bank, charge controller etc. So you send AC current from the inverter to the house, because if you try to send DC current would be very expensive to use the correct cable for 450 feet, besides the risk of resistance and voltage drop. Remember that AC power is right for transmitted over long distances. Remember to measure how much current AC going to transmit between 450 feet, so use the correct wire. I hope I was helpful.

My question is why do I have really high voltage(over 100) but less than 2 amps and other times they are both high or both low? I understand that they combine for power output, but some days I have really high voltage but hardly any amps to charge my batteries. Is it the power or amps that is charging the batteries? Thanks for your help.

Hi,
Which charge controller are you using?
