I'm designing a grid-tie solar array with battery backup. My utility requires my grid-tie inverter to be compliant to L1741/IEEE1547 standard in regards to Anti-islanding protection. Typically this means if the utility goes out, your inverter automatically detects this and for safety reasons disconnects itself from backfeeding the utility grid.
I understand completely the safety reasons for the rule but during utility outages I would still like to power a few selected loads. Are there grid tie inverters on the market that will disconnect itself from the utility satisfying the anti-islanding protection rules and bypass the AC panel to feed a few selected loads? What other options available to me?
