Calculate runtimeQuestions about this model
How much energy does the DELTA 3 Plus store?
The manufacturer lists 1,024 Wh. Conversion loss and a reserve reduce the energy available to your devices.
How much power can it deliver?
Normal continuous output is 1,800 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 11–60 V, up to 1,000 W total. Also check current, cold open-circuit voltage, connector and polarity.
