unisolar voc 23.8 , working volts is 16.5v
a bit lower than i remembered it
lots of diodes in the unisolar panels, it should be safe to connect them to the windy nation 17.4 working volts
but i might connect them to a separate controller, and parallel the outputs to the batteries, just set the controllers for the same bulk and float voltages
i'm looking at this controller
windy nation 30amp user adjustable

That unit is a solar30 controller it only has one setting. You would need to set it to your bulk then when when you wanted to float change the setting. Kinda a pain realy.
