Where each one wins
EG4 18kPV Hybrid Inverter wins on continuous AC output (12.0 kW vs 6.0 kW), MPPT channels (3 channels vs 2 channels), maximum PV input (18.0 kW vs 8.0 kW), price ($4,898 vs $1,605.56). More continuous AC output means more loads can run simultaneously during a grid outage. 12 kW is the threshold for whole-home backup of an average US home; below that you usually need a critical-loads subpanel.
The right pick depends on which dimensions matter most to you. The spec table above lays out the full envelope; the chat panel below answers "which one for {use case}" if you want a directed recommendation.
