<div>The SW's are real early in the process and we doubt the 65% or so efficiency makes sense especially with the battery losses in the process. The other dealer told me the GTI's were not available anyway, but I haven't checked. He was looking for the interface relay when I came into this process.</div>
<div>When I get down there I will check the date. it is 3 hours from here. </div>

<div>Thanks,</div>

<div>On a similar question to what works well together. I am rebuilding the wind side of an old off grid system that the new owner has brought the grid in. He wants to grid tie the system. Another dealer is doing the solar side of things.</div>
<div>My thoughts are the 48 volt SW inverters need to go, and replace them with Outback 48 volt grid tie units and have the wind keep the battery up. Am I correct that when the batteries are full from what ever source the outbacks will grid connect and net meter any excess power to the grid? Seems that I remember that they will but almost never get a call for grid tie up here in the sticks so I figured I would ask the knowledge base.</div>
<div> </div>
<div>I would suggest he keep the SW inverters to generator charge in case of a long power outage as last I knew the Outbacks (FX) did not care for generator power.</div>
<div> </div>
<div>I could probably research it but the list is faster and probably more accurate that reading all the manuals with all my free time these days!</div>
<div> </div>
<div>Needless to say the fellow in on a budrgt and the power company brought the power into the main building not the power house. Can't make things easy......</div>

<div>Wrenches,</div>
<div> </div>
<div>I have been doing some experimenting --testing compatibility between brands of grid tie inverters and sign wave battery type inverters. I am hoping some of you also have some experience here and we can compare results.</div>
<div> </div>
<div>My interest is fueled by my belief that AC coupling is the ideal way to increase system capacity for battery based off grid systems. The primary benefit is higher system efficiency for AC loads used during the day. I realize that power management becomes important but my interest right now is just to find out who talks to who. My ultimate "power management" tool will be an electric vehicle. Charging it will undoubtedly suck up available juice.</div>
<div> </div>
<div>So far:</div>
<div> </div>
<div>SMA synchronizes to Xantrex SW (have not tested the XW yet) and Outback and of course the SMA Sunny Island</div>
<div> </div>
<div>Xantrex GT also syncs to the SW</div>
<div> </div>
<div>I started this project with Enphase as my first choice since their system is so scaleable. I have been unable to make Enphase sync. Marv at Enphase has been very helpful but to date no results. I have, at Marv's suggestion ,used capacitors to clean the somewhat hashy SW output without results. Marv tells me he is testing Enphase and Outback. Does anyone have experience syncing Enphase to other offgrid inverters?</div>
<div> </div>
<div>Any experiences with Fronius and others.? </div>
<div> </div>
<div>Though the SW output is not the cleanest, the results with SB and GT are very stable. They hookup early AM and its steady green light all day long. Though I use microwave, start induction motors etc, and my scope clearly shows lots of spikes during these events, the GT and SB hang in.</div>
<div> </div>
<div>What are the experiences from others regarding mix and match?. Interoperability among brands seems to be a very desirable goal to this wrench.</div>
