No. This is an off-grid inverter, not a hybrid inverter. For this type of functionality, we recommend looking at the EG4 18k-PV or 12k-PV hybrid inverters. Question: How does this inverter address neutral-ground bonding in both on and off grid modes? EG4 says "The 6000XP architecture assumes there is a single neutral-ground bond in the system.
