I saw the article as well. I agree some of the inverter systems may include some basic features like the time of use system modes on Sunsynk, but the way I understand the article is that there is far more on offer from SunShift than integration with the EskomSePush API, and I don't have to be involved on a day to day basis with my inverter settings anymore.
Only using your system to prep for loadshedding will give a minimal additional return, as I have found through manually managing my SunSynk system the key lies in recovering from loadshedding. It is quite a manual process every day, and many of the appliances in my house are on timers to help with my prediction in terms of the load. If SunShift really can predict loads to some degree of accuracy and stays well within the battery warranty specs so that they don't kill my battery and the system automatically changes my inverter settings for me, then that is already a product worth buying in my opinion.
To really sell me on the system, I want to know if the weather, solar, and load predictions are being used to prep and recover from loadshedding intelligently because if the system will just drain my battery by default and then charge it just before loadshedding not taking into account if it is charging from the grid or solar then there is still work to be done.
