Customizable start/stop

At night, once the power consumption reaches a certain level, the smart generator will automatically start to replenish power, eliminating the need to get up in the middle of the night to reset it.

Night-care mode

Monitor the remaining power of the EcoFlow DELTA Pro 3 energy storage in real-time, predict future power consumption and measure the power generation from PV, and auto-recharge it in time to ensure a peaceful night’s sleep and rest for your family and neighbors, avoiding noise during charging at night or during peak power consumption periods.

PV-priority mode

Recharge the EcoFlow DELTA Pro 3 with PV panels, automatically prioritizing PV charging for savings and environmental benefits while minimizing noise from continuous generator operation. Need more power quickly as an outage approaches? One tap in the EcoFlow app switches back to PV and Smart Generator charging combo for swift reinforcement.
