I have a couple of projects coming up, which will require additional work to prevent connecting to a Generac Guardian's ATS panels. Do the same concerns still exist regarding back-feeding an inverter to a generator panel? Can the inverter damage the generator? I know this was the cases, at

Hi Nick, The usual answer is this is a bad idea for the generator. The only exceptions I know of are if the solar is a small percentage of the generator size, then its probably OK on the generator. jay peltz power On Feb 15, 2010, at 7:27 AM, Nick Soleil wrote: I have a couple of

HI nICK If it fits I like the ,1,2,3, approach, I have only used Outback for this, and it is for Bimodal systems. 1 is the grid, if it fails, 2 the outback picks up the priority loads, When the batteries voltage collapses the generator starts and the ATS picks up the priority laods. This is

Jay, If you already have the MC tool, then the Tyco specific tool from Tyco may be the most cost effective. We just finished a larger commercial install where we used one and it was simple and effective. IIRC it was ~$220 from our distributor. Best regards, Mark Dickson, NABCEP Certified

Jeff, That was my first choice, but I was told by Outback that they do not offer a 120/208 inverter(s). I have not set up a three phase system yet, so bare with me please. I was going to contact SMA next. Jeremy - Original Message - From: Jeff Oldham starpowe...@juno.com To:

We have bought a few recently, but be careful - there has been some manufacturing shortage (according to Multi-Contact) and all have been shipped with crimping dies for the MC-3 connector and not the MC-4s that we bought them for... Of course the dies we are told are not sold separately...

I do not know what is going on at Outback, but unless they reduced the product offering, they have the capability. I have such a system. Use 3 of their 120 volt single phase inverters connected 3-phase WYE (120/208) 3 phase. Each inverter is only a single phase, and you connect each

Hi, Does the utility mean by match that they don't want the inverter output transformed in any way? Could you not just use one 120V inverter? I've connected single 120 volt inverters (albeit not outback but I don't see why not) to a 120/208 wye without problems. You have to make sure the wires
