even inverter-type generators &#8211; are known to have fluctuating frequency such that phase-lock may be very difficult, most likely not possible.\u00a0 While this typically won&#8217;t result in any damage, the generator input would become useless.\u00a0 For best performance, please refrain from using generators on these models and apply only utility grid.<\/li>\n<li>ECO mode (grid bypass) is automatically disabled on parallel setup;
