FAQ

Which is better for day trips and camera charging?

SOLIX C1000 1056Wh has the portability advantage by listed weight, while DELTA 3 Classic 1024Wh +400W Panel provides more stored energy. Pick the constraint that matters most for this use case.

Which model is the stronger fit for overnight backup planning?

DELTA 3 Classic 1024Wh +400W Panel has the larger published capacity. Confirm that its 1800W AC rating also covers the starting and continuous load of your appliance.

Can DELTA 3 Classic 1024Wh +400W Panel 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 C1000 1056Wh run a CPAP overnight?

At a 40W planning load with the humidifier off, the estimate is ~22 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.
