<div dir="auto">I have used Simphiphy. Had a problem over time nearly 2 years the cells were what appears to be out of balance. I think i balanced them by setting the charge voltage higher than recomended. I think the factory has it wrong</div><br><div class="gmail_quote"><div dir="ltr">On Wed, Jan 23, 2019, 1:39 PM Dave Angelini Offgrid Solar <<a href="mailto:offgridsolar@sti.net">offgridsolar@sti.net</a> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Simplyphi does not have a built in method for Soc.

the install requires an energy monitor with a shunt. Too much work for me<br>
and my clients. Their batteries are too small at 3.5 kwh or so. If they<br>
changed the size up, and got Soc out to OUtback or Schneider I would use<br>
them.<br>
