In off grid solar inverter with the single panel power optimization, anti islanding protection is required or not?

No. anti islanding protection only needed for grid tie systems. Different type of inverter needed for off-grid.Powerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

But this also means that an off grid inverter (unless it is a hybrid inverter) must never be connected in parallel to another active source of power, such as a generator or other non-communicating off grid inverter.
Also, if you there is a grid connection which may be used, just not when the off grid inverter is running, you will need to have an interlocked transfer switch to prevent them from accidental cross connections. In some cases the transfer switch is built into the off grid inverter.SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment
