I hopped DESS would function without an internet connection.
I configured it using VRM saved the config.
Purpose:
Solar system is disconnected from mains power only 3 times per year.
So outside of these moments the mains is connected and currently victron just keeps the batteries at 100% degrading the health significantly.
I know DESS isn’t exactly fit for this, but ESS doesnt work since it doesnt cycle charge and discharge the batteries.
