Hi, First, pls excuse my english. I have installed a Quattro 12V/5000 on a Boat connected to several mppts, 1200 Ah of Lithium Batteries and Shorepower of 220 V.
Yesterday the shorepower stopped working (connected to AC in 1) It showed 227 V and "Disconnected" on the Cerbo and no Amps or Frequency. I checked the shorepower as we are in a shipyard right now and directly connected it to my 220 V circuit of the boat and it works perfekt as on the other 100 Ships around me. When I connect the mains back to the Quattro it only shows the 220 (227) Volts but nothing else and sais disconnected. (In German "Unterbrochen") I already did all the firmware updates. As I am right now in Greece it would be dificult to get support from my german dealer.
Anybody has sugesstions for troubelshooting?
In the summer I had already two occasions where it showed "disconected" and weird Volt and Hertz Numbers in a diffrent harbour, but after some hours it went back to normal so I thought it was just "bad" electricity on the mains.
Thanks
Ralph
