  1. BMS COMMUNICATION ERROR

    Bhuba replied to Bhuba's topic in Inverters
    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.

  3. BMS COMMUNICATION ERROR

    Bhuba posted a topic in Inverters
    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
