How long can the DELTA Pro run a fridge?

A typical fridge draws a few hundred watts, so the 3.6kWh base can run one for roughly a day or more depending on duty cycle. Add batteries to extend that for multi-day outages.

Can it be expanded beyond 3.6kWh?

Yes. EcoFlow sells add-on batteries that take the system up to 25kWh, and the DELTA Pro supports multiple expansion batteries in one setup.

How fast does it recharge from a wall outlet?

EcoFlow rates wall charging at about 1.8 hours for the base unit with the right circuit. Solar input is also supported for off-grid recharge.

Is it loud when running heavy loads?

The fan runs under heavy draw and owners report audible noise. It is quieter at light loads, so placement away from sleeping areas helps.

What can the 3600W output run?

It can run fridges, space heaters, microwaves, power tools and most household appliances within its wattage. High-surge items like well pumps may need care.

Does it work with solar panels?

Yes. It accepts solar input and can be paired with EcoFlow or third-party panels within its voltage and wattage limits.

About the EcoFlow DELTA Pro 3600W Portable Power Station

The EcoFlow DELTA Pro is a portable power station and home backup battery with an expandable system. It starts at 3.6kWh of capacity, expandable up to 25kWh. It has 3600W of AC output, which X-Boost technology expands up to 4500W. Two units can be paired for 7200W.

It uses an LFP battery rated for 6500 cycles before reaching 50% of its original capacity. EcoFlow's battery management system monitors and regulates voltage, current and temperature in real time. The unit has wheels and an extendable handle for moving it, and a dedicated 30A Anderson port.

For home backup, two DELTA Pro units can be chained with the Double Voltage Hub and connected to a breaker panel through a transfer switch, for up to 7200W and 21.6kWh. This needs no rewiring. The Smart Home Panel (sold separately) connects the unit to home circuits and can power up to 10 circuits during an outage. It can be charged in 6 ways, including at EV stations, and up to 6500W with Multicharging. A DC-coupled EcoFlow Smart Generator gives up to 40% more efficient charging with less energy loss. The EcoFlow 800W Alternator Charger recharges it from a vehicle.
