    Growatt SPF trips GFCI occasionally.

    I have a Growatt SPF 3000TL LVM and installed it in a RV. It's working great, aside from one little issue. Input GFCI trips occasionally. When I'm at home I plug in the RV with an adapter into an exterior 20A outlet (reduced the charging rate) which is protected by an GFCI outlet. After...

    Autostart for Onan RV Generator - Growatt

    I got a Gasoline Onan 5500w Generator in my RV which I want to control with my Growatt NC NO contact. The Growatt switches when the battery voltages goes to low - and switches back when sufficient charged. Means I got a high signal while it's calling for charge. My Onan expects something...
