We've been having good luck with SImpliphi, the pricing has recently gotten much more competitive.  As it's names states, its simple.  Each 3.8 kWh unit has an 80 amp breaker built into the top, weigh about 75 lbs, and are a bit smaller than an L16 but with carry handles.  We use an insulated 2

There is another aspect to the 10’ rule which is, its protection for the array from wildfires. 10’ might not be enough for that though depending on where you live. In regards to what’s being discussed, I have many ground mounts (not talking pole mounts)out there, I try to have them as high off

Fortress EVaults have their own lcd screen with Soc, but Dave is right, it's not as accurate on RE Optics. We do get a battery reading without any add-ons, they are just usually off up to 10% from each other. > > > Hi David, > > They all work but none of them can get Soc and a few other > things ou

Hi Ray, Which XW? There are 3 now. The old graybox XW defaults at 44V LBCO and the range is 40 to 48V. There also was firmware back in its day that got older units updated. Schneider still has the firmware under discontinued products. XW+ is default 44V and adjustable 36 to 44 vdc. XW pro i

Hi Jay, Been awhile. Pretty weird times. Really nice to be off the grid, I think you would agree! The answer to your question is you don't know if it is accurate. I would call the tweaking of the numbers programmed into Flexnet or the Schneider bat mon :"for indication only" You can observe it

I see what you mean Ray. Sorry I misread your mail. There are not too many batteries out there that need LBCO above 48V. Which ones are you talking about please? DAVE ANGELINI OFFGRID SOLAR "we go where powerlines don't" http://members.sti.net/offgridsolar/ [1] e-mail offgridso...@sti.net [2]
