This gen has a significant phantom load, & there is no way to avoid it. I have installed several & had to provide either a 10 watt PV module or a 120-12 volt battery maintainer.

I too hope that is fixed. It looked to me that the offgrid warranty is 1/2 of grid-tie. --Dave > What is the standby current draw on this unit.
