<div dir="ltr">Bill,<div> Now that you mention it I did not have an SPD near the inverter, I have one on 1 of 2 TOP Racks, other rack with old Delta... My inverter lives on my workbench to allow swapping other inverters in for load testing using my whole house with everything connected to ancient wiring which did not include an SPD. I put them on all my customers' systems and have had no issues on most of them and have never had to replace one. . I have removed lots of those grey cans but have not taken care of my own system !!! The Fortress eflex was not fully protected either. That strike would have been the perfect test of the SPD's if I had them all installed. I had a perfect real world test of</div><div>Outbacks ACA with surge protection on two GVFX inverters that had annual lightning failure until I installed their surge protectors. There have been no more failures since (at least 10 years) The lightning was so severe at that location that the power company was constantly having issues on that power line. </div><div><br></div><div>John</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Apr 12, 2024 at 12:31 AM Bill Battagin via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><u></u>

<p>John,</p>
<p> Just curious if you had SPDs (like Midnites) in
either system? AC side, DC side</p>

<div>I am going to try a Fortress Envy at my off grid home but
will keep my Outback field repairable VFXR wired in just in
case. I had a massive lightning strike between my house and a
guest cabin 1/4 mile away and I lost power from my Fortress
Eflex battery at the cabin and my Outback inverter at my
house. I replaced the control board on my inverter ( I always
keep one in reserve as it is usually the only board failure
due to lightning) and was back on line in 1/2 hour and
Fortress rushed me a new BMS board for the E-flex and a day
later and a half hour swap had it back in service, Now it is
a different story with 2 Simpliphi batteries I have from a
customer that failed. I have to ship them to California to
have them evaluated to see if we had damaged them by misuse.
Lots of expense and time lost.</div>
