"Fearless" posted some good videos showing the insides of the SUN 250 and Power Jack 300 Grid Tie Inverters.

The circuit board is exactly the same on both units, and most parts are also.

In this video he compares them and it looks like the programming of the internal CPU differs so it's possible that each company selling these programs them differently.

In an earlier test you can see some of the same things happening when they are both connected
