Hi Loren, We try to stay off the roof for off-grid in Colorado but I'm about to do an 8 panel, 2 string system because of a building code where this cabin is located. I talked with Tigo about it and the parts list is:
8 x's Tigo TS4-A-F for each module 1 x's Tigo RSS The RSS will signal the TS4s to shutdown if power is lost to the RSS. Included in the RSS box is a 120 Vac to 12Vdc out power supply. However, since the RSS is 12 vdc (max of 1A) I'm getting a buck converter to power this so the inverter can be turned off in the winter time when the cabin is unoccupied. The cost isn't too bad. I'll be honest though, I think this is a terrible idea. Any communication box that can shut off charge to the batteries over winter at an unoccupied site is asking for trouble. A communication glitch and the batteries will be dead. This site is about 2 hours from the closest fire department so there is nothing to be gained from adding this equipment other than passing inspection.
