    Hello all, having lived Maria as well, I can say that it was in fact 5, but it felt something like medbiller said.  Anyhow, being a noob here too I wanted to ask exactly how is AC Pass Through works.  I have the default of 50V on my XW+6848 and at some point during the night (when battery voltage is ~49.5) it just stops inverting from the batteries and lets AC1 get all the loads.  During this time, the current to both battery banks (2 banks of 8 Deka Solar 8L16) fluctuates between -3A and 3A, keeping the voltage between 49.6 and 50.1.  Can anybody explain me what the inverter is doing or it is supposed to do?  Finally, I appreciate any comments and your time to illustrate me and other that may have the same question.  Thanks!

    The inverter charger has many user programmable settings and will do what it is programmed to do. The 50V LBCO default will stop inverting and pass the grid or genset thru.

    You need to tell us more, like do you sell to the grid? Is there solar? and what you have programmed from the defaults. I have an idea what is happening but need more info.

    Maria really sucked and is still a major issue in PR, as you know.
