J10 stepped sine wave approximation

I'm considering purchasing J10 or an S10. It's not clear to me whether the J10 produces a stepped sine wave approximation at all times or only when it's on battery power, i.e. does it produce a true sine wave when running on AC?
Thanks, Stuart

How many steps does the modified sine wave have? Are there specific UPs or inverters that have a multi step sine wave (16-32 steps for the full wave)?

Hi Stuart,

The J10 will only output a stepped approximation sine wave when on battery. When online it will output filtered utility power so you will get a normal sine wave.

Hope this helps.
