The IMO FireRaptor units are as far as I know immune to any interference from charge controls or inverters. It does not rely on wireless or power line communications. It is simply a hard wired module level disconnect that runs on 24VDC. It has two-wire daisy chain cables between them, with a nice c

I may have spoken too soon on this. It turns out that the LSOB system just does not work with PV charge controllers. The Princeton Power Systems DRI-10 inverter has charge controllers built in, which is why the system was not working. Cheers, Dave *Dave Tedeyan, PE* Senior Engineer | Taitem Engin

Just a note about midnite's SOB rapid shutdown system. It does not seem to work with all inverters. I was recently helping someone with a Princeton Power Systems inverter add in rapid shutdown. There was some kind of line noise coming from the inverter that was causing the rapid shutdown system to

Try Tigo, they have a MLPE shutdown wireless and does not use PLC (Power Line Communication). With an unknown inverter, the inverter switching noise may trigger the Tigo's PLC to keep on or shut off. Shutting off the inverter stoping module array current, and the AC supply to the "Gateways" los

Dear Wrenches, We are installing a system for a project we did not design. The plans specify 5 Ginlong Solis inverters. Ginlong does not make their own rapid shutdown device, so units by Innovative Solar Products have been specified. The Innovative Solar rapid shutdowns are made to order and wi
