simulation software for off-grid systems

engineer

Is there anyone familiar with Homer energy microgrid software? I used the free version for a small simulation. It was very limited. And the sensitivity analysis was a bit weird. I don't know whether the simulation matches empirical data or not. I am a bit skeptic about it. If there is someone who has experience with it, can you confirm that the data is accurate or not, and do you recommend buying this software?
Thanks.

I built my own simulator so I cannot speak to the ones being sold. I can tell you the simulation will be accurate if the correct formulas are plugged in and the right data is input.
