Can't second this enough. I have a Sunsynk inverter here in South Africa where we deal with multiple-daily grid outages. So the priority is always set (based on time of day) to keep the batteries charged "just in case". If Solar can't provide enough juice, it sucks from the grid.
The whole thing is actually quite elegant. It turns "electricity" into this fungible thing like it was supposed to be in the first place. More pro points, you can plug in an electric-start generator and configure it to start automatically as needed in order to supplement the solar. Going further still, you can plug in a wind-turbine and have it blend it into this whole system.
Makes me wish I could install a wind turbine on my roof. A fair bit of solar, coupled with a little bit of wind suddenly makes your batteries go a really long way towards being fully off-grid capable.
