Good morning.
The problem concerns Zendure Superbase Pro 1500 and the lack of stability of DC charging from photovoltaic panels. The charging power under a cloudless sky and full sun ranges from 70W to 140W, it does not maintain a constant full power of 140W. I have two Zendure Superbase Pro 1500 and it is the same on both of them, checked on other panels, for example 2 x ECOFLOW 160W where the charging power was also not constant from 150W to 230W where the maximum charging power should be maintained all the time. Connected to the socket XT60 FW latest. I'm adding a video, does anyone of you have a solution to the problem?
