  1. [SOLVED] Growatt SPF5000ES USB B port not working (?)

    Berni replied to Dæv's topic in Inverters
    You must use USB A but it's a RS232 port (D+ and D- to TX and RX) using a max232 like to convert to TTL..

  3. Growatt SPF 5000 has different parallel board which does not communicate

    Berni replied to Deyan Vitanov's topic in Inverters
    You can build your own by simply connecting 4 Keystone Jacks in parallel. In fact you only need to connect 3 pins (1,3 and 5 if I remember correctly) I have the exact same setup of 4 SPF5000 and 6 UP3000 and they work like a charm!
