Simpliphi has been around since 2002, so they actually are older than their 10 year old warranty.  Most other companies can't make that claim.  As far as reliability, each 3.8 kWh is independent, so you can just shut down a bad unit and send it in for repair. I'm building systems with 4 to 6

Hi Wrenches, A client alerted me to the fact he can't connect via the Conext Solar app on his phone for the last few days.  I tried and got the same thing "Service Unavailable - try again later". The website works fine - but anyone else having the same result with the phone app? Sandra H?

Discover Battery has been around since just after WWII. I think that since each Li battery is native to the system voltage, the way to get some redundancy is to simply have more than one battery, most systems will anyway. Then if one fails you can use the other ones until the failed one is

Hi David, I have used "Iron Edison" they will custom build a LiFe PO battery to your specifications There may be a way to combine LiFe and Pb acid, using the LiFe PO for cycling and the Pb for high energy. If cycling is a smaller portion of the load. On Fri, Mar 20, 2020 at 3:00 PM David Katz

Bill, I too have the same issues and the only reliable (long term) way offgrid is to have both chemistries. You get the best of the new battery types (partial Soc tolerant) and the reliability of a a LA battery without any electronics adding new ways to lose power. By having both hooked up to

Wrenchers,             I seem to continue to have my foot stuck in the past regarding off-grid.  Off -grid seems to have more of an element of a need for reliability, redundancy, klugability.  Believe me L-ion batteries and especially the "total units" like the:

Ray, I agree it is a kludgey way to accomplish a low battery cut off. But, it doesn't change the no load draw issue. No load draw is still a problem even if the normal low battery cut off adjustment has enough range. At least with most lithium batteries there is a secondary shutoff. Kent

That was our kludgey plan, if Schneider can't do a firmware update.  The issue I have with that, is the no load draw of the inverter is still 25 watts, so eventually it could still pull the batteries into full shutdown. Ray Walters Remote Solar 303 505-8760 On 3/23/20 10:30 AM, Kent Osterberg

Another way to buy more time with simplyphi would be to minimize LBCO hysteresis voltage and LBCO delay time. This would shut down the inverter sooner. They appear to be set at the defaults and could go lower. Dave Angelini Offgrid Solar "we go where powerlines don't"

I like that approach, Jay. Great idea. It gets the job done and is self contained - using only the features of the inverter. The remote power off could still be used with another remote switch. If there aren't enough aux output ports in the system, one could add a Morningstar relay driver.

Hi Kent, Yes that’s what I mean. According to the manual I’ve got, up to 52v for the low, 64 for the high. Which is high enough to do what the simpliphi needs. Jay > On Mar 22, 2020, at 5:37 PM, Kent Osterberg wrote: > >  Jay, > > Do you mean: use the Aux relay to activate the Remote
