More Solar for "Us"
Ok, I went off.the deep end? Bought 3 used 37watt uni-solar panels and a blue sky 2000e controller for the hefty price of $400, They were being listed as 75w panels, they are not The tested open...

By setting the higher voltage and the longer boost times plus the return to boost voltage
The controller doesn't wait for the voltage to drop low before returning to boost
This lessens the strain on the batteries
I thought that Float mode had the fastest response - controller current would increase immediately when loads come online, while still maintaining Float voltage. At least, this is the case with my MPPT.
That is, - if there is enough sun and enough panels. When there is not enough, I don't understand how higher voltage setting can help. My controller in this case would revert from Float to Boost/MPPT, and would bring the voltage up only as high as the available net current into battery would allow. It would attempt raising it to 14.6V setting if possible and then go into Float again.
If there is too much load and too little solar input, then the current out of the battery exceeds the current in way too much, and the voltage would drop no matter what. You can't give batteries more solar power when there is nothing to give.
