On pro-solar ground mounts, up in the mountains, we do not use the pinch screw on a Hollender pipe tee. We use pinch screw as a pilot for a bolt. That makes the Engineer happy and he signs it off. Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgridsolar/ [1]

I do not see the need for high voltage battery systems offgrid. Neither does Schneider, Outback or Magnum. I was involved with electronic field testing with a 400vdc model (all in one) that was not released. There was not a significant market for it. The new Outback Skybox (all in one) is going t

Hi Dave and All. Reasons for HV batteries off grid? 1) Smaller cable size (I just did an 18 Kw off grid with 4 SIs and the cable costs alone were in the order of $400) and increased flexibility locating batteries and inverter. 10 AWG plug and play. 2) Higher efficiencies. Easy integration

A more recent spec sheet shows the MPPT window starting at 200v instead of 250v, which is a significant improvement. Brad On Tue, Sep 25, 2018 at 2:41 PM Dave Angelini Offgrid Solar < offgridso...@sti.net> wrote: > AEE had a training course webinar. The screenshot is from them and they > say Oct
