Die Anzeige ist leider nicht besonders Aussage-kräftig, dafür gibt es weiteres (nicht ganz billiges) Zubehör zu kaufen. Wir hatten zuvor einen günstigeren Regler im Einsatz, der leider aber nicht gehalten hat. ### ⭐⭐⭐⭐⭐ Solar Regler SR 140 Duo *by M***P on Reviewed in Germany on 16 April 2016* Sehr guter Regler habe ich schon lange gesucht kann ich nur weiter Empfehlen.
