UB right, Tump. These things aren't exactly something you will ever find at Home Depot! BUT, and it's a big one, if you count all the %$!#& time and energy usually required to design, fabricate and re-design a really good off grid system, the extra money might just be woth it. ;-) Matt T Tump

Geoff, SMA suggests using an OutBack Autoformer. Yes, I know it sounds weird to suggest using a competitors product, but this is not the only weirdness when using the 60 Hz SI system! They /also /suggest using the Flexware DC breaker box, as there is really nothing they make that accomplishes

Jay, Nope. We are stuck with just what they are offering in the US market - maximum of 4 units in single phase and 3 in three phase. A bummer for sure, considering what is possible in the 50 Hz version! Matt T jay peltz wrote: Hi Dana, So is the issue that any 120v 60 hz units are all th

Hi Dana, So is the issue that any 120v 60 hz units are all the US versions, or do they have 120v 60 hz international versions ( probably non UL)? My asking is that I've got some large projects in Baja that could use full feature and larger stacking than the US version. thanks, jay pelt

Thanks for the report, Steve. I'm also a huge fan of the European SI. We need to be careful when we start to compare operations across the ocean. The US version of the SI is a bit different from the European version. SMA in Germany decided that the full-featured SI would be too expensive for the US

What about the new Surrette FC420's? The latest SOLARPRO mag has a tiny blurb on them at the bottom of page 28. Two sets in parallel (630 a/h) would meat your criteria and would perform much better than sealed batteries. I have been beta testing a set here at home and they seem to be doing fine

Hi Geoff, Nice heads up on the SI needing to be “set up” prior to commissioning. We are getting closer to a similar design ourselves. We have a SB7000US being fed by 36 Sanyo Hit Power 200’s on the drawing board that we are going to feed into a grid tie inverter system. Right now I am convinced

Matt- What is your prefered/recomended way to address the 240 VAC SB series (we typically dont want to use a bunch of 700s or 1800s) and the 120 VAC SI series?  We used a pair of Outback PSX-240s but that was extra work/cost.  Other (larger) transformers? Torroid coil? Eaton? I'm surprised

Hi William, I should go into a little more detail about how to hook up the system with an inverter having both AC IN 1 & AC IN 2, with the entire service backed up by a generator transfer switch. There are a couple of ways to accomplish the hookup. With one method, you will need to make ta
