<p>I finally heard back from Fortress, I'm going to try their
suggestion of "equalizing" the batteries at 55.5 v, and adjust
some settings. I'll report back to the list on what I come up
with. This is an interesting application: quad stack of VFX
inverters with Midnite CCs. Using the aux out on the Classic to
control a relay to turn on/off the inverters for LVD, since
Outback programming (like Schneider) won't allow LVD settings
above 48v.<br>

Fellow Wrenches;<br>
<br>
Based on glowing reports from the RE list, I finally
used Fortress for a <br>
battery replacement for a long time customer. Overall,
it seems to be a <br>
better solution than others I've seen. However, we are
having issues. <br>
First the two batteries are supposed to be linked
together in a master/ <br>
slave configuration, but they charge and discharge
unevenly, and have <br>
SOC often 20% different. Batteries are connected to a
common buss with <br>
equal length 4/0 cables.<br>
<br>
I've been truly disappointed with Fortress customer
support. First, I've <br>
called multiple times over the past two weeks, and never
got through to <br>
anyone. Their online support system is quite flawed as
well, and I had <br>
a very difficult time even setting up a support ticket.
Now I can't <br>
even log in to view the support ticket, and I've only
received one email <br>
back asking if I had properly paralleled the batteries.<br>
<br>
Has anyone else had a hard time with Fortress support?
Does anyone have <br>
a direct contact? Customer is beyond pissed now, after
almost 2 weeks <br>
hearing nothing, and having spent tens of thousands.<br>
<br>
Thanks;<br>
<br>
