Rogue 30 is too small these days when people install 500+ on their rigs. MS MPPT 45/60 aren't bad too.
About 600W not being enough in winter.
Baja Norte, not much difference from SoCal in latitude, fewer clouds, no such thing as marine layer.
Neighbor on the right - tilted fixed 160W solar, 9 months a year living, older propane fridge without electronic thermostat, laptop, propane heater. No generator. Washer/drier trips to the village once a week. I told him to add more watts so that he could at least run some big fan in summer, he said he'll "think about it". Old people, old installs, they still think of 300-400W as of something big and expensive (it was back then, yes).
Neighbor on the other side - same thing, two people there.
Neighbor across the street - tilted 350W, rotated twice a day to follow the sun, same loads plus satellite TV and i-net.
