    Получил через 15 дней! Качеством доволен. Мой литиевый аккумулятор 48V 14A заряжается отлично от солнечной панели 310W! Продавца рекомендую!

    Some transport damages

    As the unit arrived there was something loose inside. I opened the unit to find out that the loose component was N-channel MOSFET "045N10N". I got a replacement locally, soldered it in and now the unit works perfectly. The MOSFET legs were broken right outside the TO-220 encapsulation probably during transportation as seen in attached picture. I am still giving high grade for the product as I think it is great value for money. Replacing the MOSFET was no issue at all for me, but I guess not everyone

    the first impression is excellent! there were some reviews that the charger goes OFF state when input power goes OFF and comes ON. I haven’t observed that; probably this has been fixed at firmware level.
