The 12000XP is locked into off-grid without software config. Hybrids are more commonly (like, i suspect > 75% of this one) used for grid tie.If you cannot grid tie the 18Kpv is dumb. The 12000XP is basically the exact same, slightly different PV input config, only 2x26A MPPT instead of 2x15 and 1x25, both are 50A likely exactly the same inverter hardware, and the 12000XP is 1/2 the price.
This is definitely the kind of thing that will trigger some lawyer action on the interconnect rules.
