48v20a or 96v20a, which takes longer to use 5 kW inverter, and how many hours does it take to use 3 kW electrical appliances?

Of course, the time of 96V is longer, but it seems that no inverter with 96V input has been seen in the market.

The input voltage of inverter is not universal, 48V battery needs 48V inverter, and 96V battery needs 96V inverter.

Service time (hours) = battery voltage x battery capacity (AH)X 80% (average efficiency of inverter) ÷ load power (required electrical power)
