Hello my tests after 1 month of use are successful, even in winter! My 4 batteries I knew almost empty (regulator posted only 1 indicator filling red) after connecting panels 20 w 1 and 1 month of winter sun: sun presence indicator reacts well, load indicator lighting permanently (batteries are not yet full ok we will wait to see if he goes out), but I reached the third red lights détat battery that is partially lit to date. 1 only downside! as quélectricien, I installed electrical starts for battery maintenance and when I cut the lights détat load remains as it is when there is more batteries as if there was a memory? ??
