Only took a couple hours to wire up and mount the combiner box.

Something about larger wiring like this is enjoyable. So much less fiddly than what I'm used to.

Update: The panels have an open circuit voltage of 35.89 and are in strings of 2, so I'd expect to see 71.78 V with only my multimeter connected. So I'm losing 0.07 volts to wiring, which is less than I designed for.
