<br>
So yes the Load will be hot with Grid Pass-thru - The Sol-Ark has 3
breakers - Grid (63A) - GEN (50A) - Load (63A) (European type
breakers). I have not experienced the delay that Nick observed but
perhaps cause I've always had batteries on them.<br>
<br>
The nice thing is that with the software and phone app on both you will
be able to program all settings remotely for the client.<br>
<br>
As to the Anderson battery disconnect idea - my biggest issue with all
battery systems these days is folks not using proper OCP on Parallel
batteries. With 48 Volt Lithium now in small increments if you parallel
6 server rack type 100 A rated batteries together you are already at
600 amps and then if you parallel 4 racks of 6 you are at 2400 Amps!
Yes each battery has a 100 A Breaker but I see few installers really
dealing with the fault possibilities in between.<br>
<br>
Attached is a Victron Fuse setup I did for 30 100 AH batteries on 4
Sunny Islands. It was 5 racks of 6 batteries. I put each of the 5
racks on a 200 Amp Fuse and each Sunny Island on a 200 A fuse in this
box.<br>
<br>
So with the Anderson's you might want to think what amperage fault
potential is where when you unplug.<br>
<br>
Hope that helps!<br>
<br>
Best,<br>
<br>
Jeff<br>

a follow up, he's considering connecting a battery bank with an
Anderson connector. This is not the golf cart scenario I mentioned in
another thread, but he wants to be able to wheel away his battery into
storage. Don't ask me why... I can't figure it out myself. Do you see
any issues with this? I guess the question I have is what happens when
the battery is connected and he's on grid and he decides to disconnect
the battery? I'm guessing nothing, but I could be wrong. Will he need to
change the settings back to grid-tie only?</div><div

this will work just fine. I\u2019ve not fully embraced a transition to their
products for my clients yet but had one recently where the customer
insisted on this for their project and I was in the exact scenario while
we waited for the battery to arrive. No external bypass required for
this reason. However it does not work without a minor setting activation
and even then there was a 10-20 second delay before the relay is closed
and the utility will pass through. <br><br>Nick<br><br><br></div><div><br>_______________________________________________<br>List
