Seems to work well - used to keep motorhome battery charged when not in use
Visual display is informative- only thing lacking are the Amps being put into the battery

set up instructions not too clear.
works ok but you need to read through the instructions a few times, English does not seem to be the first language and some parts can be "confusing".

Doesn't work at all
Everything connected up - multimeter says solar panel and battery are working perfectly, but nothing on the charge controller

Billige Kunstofftaster/schalter
An dem Produkt hatte ich wenig Freude. Nach einigen Tagen waren die Bedienknöpfe eingedrückt und kamen nicht mehr aus dem Gehäuse. Daher zurück gegeben und ein etwas teureres Gerät gekauft.
