Can you elaborate?

The Solarman app (and its web-based equivalent pro.solarman.cn) is a public interface, the config of your Sunsynk is literally protected by a userid and password. This is considered pretty weak authentication, humans can choose weak passwords and / or re-use passwords across various sites, take a look at https://haveibeenpwned.com. There is 2SV on registration but not on subsequent authentication.

This means that an attacker who discovers your password in a previous data breach, or who successfully guesses your password, can alter the config of your inverter. 

Firstly, when adding this kind of functionality, Solarman should rather make it opt-in, givng the user the choice in taking the risk. Secondly, 2FA should be mandatory for any config changes coming from a publicly available interface.
