Method: nameplate capacity x 0.85 / device watts. The 15% allowance represents typical conversion and system overhead for planning. Actual duration depends on load behavior, temperature, battery state, and power mode.
FAQ
Which is better for mobile work and device charging?
DELTA 2 Max 2048Wh has the portability advantage by listed weight, while SOLIX F3000 3072Wh provides more stored energy. Pick the constraint that matters most for this use case.
Which model is the stronger fit for RV or van power?
SOLIX F3000 3072Wh has the larger published capacity. Confirm that its 6000W AC rating also covers the starting and continuous load of your appliance.
Can DELTA 2 Max 2048Wh run a refrigerator?
Its listed AC output is 1800W. If the refrigerator's running and startup demand stay below that limit, the planning estimate at a 60W average load is ~29 hours.
Can SOLIX F3000 3072Wh run a CPAP overnight?
At a 40W planning load with the humidifier off, the estimate is ~65 hours. Heated tubing or a humidifier can materially increase consumption.
How are the runtime estimates calculated?
Each estimate uses 85% of the nameplate watt-hour capacity, then divides by the stated device load. It is planning math based on specifications, not a measured result.
