Open manufacturer source ↗Is this model right for me?Uses and regional considerations
Longer outage essentials, high-output appliances and expandable home-backup systems where size and weight are secondary.
At 51.5kg this is a wheeled home-backup unit rather than a casual carry. AC outlets, output limits and charging hardware differ by region.

Calculate runtimeQuestions about this model
How much energy does the DELTA Pro 3 store?
The manufacturer lists 4,096 Wh. Conversion loss and a reserve reduce the energy available to your devices.
How much power can it deliver?
Normal continuous output is 4,000 W. A short surge figure does not prove that every motor or appliance can start.
Which solar panel can I use?
The documented input range is 30–150 V, up to 2,600 W total. Also check current, cold open-circuit voltage, connector and polarity.
