  1. Hi, Ianvn. Thinks very much for your advice. Did you replace your comms cable with the same orange one or did you get a different one because the one I have is also orange.
  2. Hi, Everyone. I am also new in solar energy. I have recently installed solar power kit in my house ( Growatt off Grid inverter SPF 5000TL HVM-WPV, with Dyness B3 Lithium battery). My problem is the communication problem between inverter and battery. Each time I switch on the battery the inverter shuts down power from grid and PV. I get error "20". I have connected the battery communication via RS 485 port of the inverter. The Dip switch is set at #2 and #3 On. Please help. regards
