Description
EcoFlow DELTA 3 Classic
The DELTA 3 Classic, with separate rated and surge figures.
The station combines 1024Wh of LFP storage with 1800W rated output and a separate 3600W surge specification.
Choose the station around the devices and connections you actually need. Stored energy, output limits and the selected package each answer a different part of that decision.

Build the setup around these details.
1024Wh LFP battery capacity Capacity is the stored-energy budget. The connected load and system losses determine how that energy is used.
1800W rated output; 3600W surge Check the connected equipment against the rated output and any separate surge or waveform requirements.
OASIS 3.0 app control Use the manufacturer’s supported app and connection instructions for this model.
Plan the load and the energy budget.
The capacity figure does not promise a fixed runtime. Connected devices, their operating patterns and conversion losses affect operating time. Check voltage, rated output and startup demand before connecting an appliance.

Before you choose
What selected configuration or accessory condition should I check?
This listing is the standalone station; expansion batteries and solar panels are sold separately
How should I compare capacity and output?
Capacity describes stored energy. The rated output and connection limits determine which loads can be connected; any surge figure is a separate short-term specification.
Can I assume a fixed runtime?
No. Runtime depends on the connected load, operating pattern, conditions and conversion losses.
