<div dir="ltr">Hi Loren,<div><br></div><div>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.</div><div>I talked with Tigo about it and the parts list is:</div><div><br></div><div>8 x's Tigo TS4-A-F for each module</div><div>1 x's Tigo RSS</div><div><br></div><div>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.</div><div><br></div><div>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.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Sep 27, 2019 at 11:24 AM Lorenzo Ortiz <<a href="mailto:lorenzo@cal-solar.com">lorenzo@cal-solar.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Wrenches,<div><br></div><div>Are any of you looking ahead at solutions for module level rapid shutdown for off grid?
