[RE-wrenches] Inverter On/Off Switch use Outback FX

[Ray Walters]

Hi Mac;

I've used the aux control on charge controllers to turn on/off the FX 
inverters, just as you planned.  Works fine, and solves the LBCO 
programming issue.

Now, if someone from the manufacturing side could PLEASE explain why 
they limited the LBCO on all these inverter models. Absolutely makes no 
sense.  Schneider, Outback, even Magnum is too low.......?
