Re: [RE-wrenches] Monitoring large PV systems
AlsoEnergy bought a company called Locus Energy, Locus NOC, and bought a company called Deck Monitoring. All good platforms. I have worked with both of those and they work well for commercial revenue grade monitoring and weather reporting equipment integration. Also Energy also bought Draker Labs. What device are you going to work with, or planning to work with William ? I have info on LGate products.

Re: [RE-wrenches] Tigo Rapid Shutdown equipment
Aloha Chris. We have been working with Tigo on repairs of a 10 or 11 year old system consisting of 352 original Tigo MMES075V units on a commercial rooftop. Original installer went belly up. The 100 kW Satcon inverter needed repairs. (got it repaired !) The Tigo monitoring system was OFF-line for many years. We put in a new communication access point, and found 3 units off-line. Since that time Tigo warranted the damaged units with swappable Tigo's TS-4, helped with commissioning the new units, reprograming ALL existing units with new updates, and has been very communicative and helpful. In my opinion, still a solid product, and still working strong. Not going to work for your thought on AC coupling, but in my opinion, a good company to work with if you decide on DC.
