It's rather funny that the GC (stands for generator control) functionality was added due to feedback from this forum and now that EG4 developed and added it, people are upset that it made the product a bit more expensive.
That said, I think some of the differences with the new chargeverter is poorly noted and make the higher price a fair representation of the value added.
The new chargeverter has a removable input cord, so swapping from 120v plug to 240v plug is very easy. The output is now Dexgon (similar to amphenol) connectors so the output cords can be easily unplugged - and shops like mine will soon be able to offer custom cables could provide you whichever length and ring terminal config you like - or give you options if you need to move the chargeverter between systems. The screen is way better too, overall efficiency is significantly increased meaning less energy wasted as heat.
