<div dir="ltr" class="">Hello Wrenches,
<div class=""><br class="">

<div class="">I'm trying to solve an issue with an older Outback FX
system. It's a quad stack of Outback 3648 FX inverters and he
has a couple of Fortress eVault and an unreliable generator.
The LBCO setting can't go high enough to cut out before the
eVaults cut out so he occasionally will have to direct charge
the eVault to get things running again.</div>
<div class=""><br class="">
</div>
<div class="">I'd like to use a 12V Aux relay logic to trip the primary
inverter on/off contacts before we go into battery shutdown so
the solar has a chance to recover the system. Pretty simple
overall but I wanted to see if there are any known ill effects
of doing this with substantial load on the system. Of course,
I can use a power relay but this may be better.</div>
