Questions about this model
Are output power and battery energy the same rating?
No. 2000 W is rated AC output power, while 4019 Wh is nominal battery energy. The folder name JN 4KWH is the product designation; use the sheet’s exact energy value for comparison.
How should backup runtime be evaluated?
Runtime depends on the connected loads, usable battery energy, conversion losses and operating conditions. The nominal energy figure is not a guaranteed backup duration.
