November 20, 20223 yr Hi, I recently had a Growcol inverter (GRW 5K 48VDC) with a Pylontech battery (US3000C) installed. I connected to the wifi, set the Growcol to "Pyl" for battery parameters, but I get error 61 the whole time. I was told to make a custom ethernet cable (Pin 3-8 and Pin 5-7) I did that, but I still get the error. Is there anything specific I need to do? Or is there a different cable config I must use? Any help please. Thanks.
November 23, 20232 yr Pin 3 and 8 and pin 5 and 7 what about ground pins ? sure there is a tx and rx pin but no ground 😕 ? I too am trying to find the cable pinouts to connect my US 3000 C batteries to my Voltronic inverter , I located a cable on Ebay for this and purchased and received it the next day but it does not work ... I contacted the seller who sent me instructions on how 🤔 to connect the cable that I was connecting corectly ! Well I then reviewed the the advert and the cable I received the RJ45 is on upside down 😔.
