DC stores the highest explicitly published single path, the 120W car outlet; the two 60W DC5521 ports are not summed. USB-C likewise stores the 100W single-port ceiling.
Runtime Starting Points
These are formula estimates using the tracked capacity, a 10% reserve, and each scenario's default wattage and duty cycle. They are planning starters, not measured runtimes.

Good fit when
- Capacity is in a mid-size planning class that can cover many overnight or essential-load scenarios when reserve and efficiency are included.
- Tracked AC output is high enough for many household plug-in loads, but surge still needs a separate check.
- USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
- Tracked solar input is 800 W before panel, weather, angle, and controller losses.
Watch out for
- Surge output is tracked, but device startup behavior should still be checked against the actual load.
