Sol Ark 12 inverter in off grid situation without batteries?

This site may earn commission on affiliate links.
I'm trying to get an answer for a friend with an existing grid-tied solar array. He is asking if there is any inverter available that can direct power to the house without battery storage in grid-down situation (obviously only at times when there is solar production). It looks like the Sol Ark 12 has this capability.... can anyone confirm? thank you

The Sol-Ark can operate without batteries when fed directly with Solar (DC coupled) but what you're describing is AC coupling the Sol-Ark to a grid-tie inverter. I don't think AC coupling is possible without batteries. With a ~$6k budget a better option might be a more affordable AC coupled inverter combined with a small battery. OR a way to run the DC lines to the Sol-Ark instead of the grid-tie when the grid is down.... or are you suggesting to replace the existing grid-tie inverter with a sol-ark?

The most affordable backup option would be a SMA inverter with Secure Power Supply. That would be ~$1500 vs ~$6k.
