Hi. I have the Sunsynk 8.8kw inverter and 2 x Hubble 5.2 batteries. The system is working perfectly. I do however have one problem. Sometimes I lose the feed to the AC load values. It reads zero on the dials and on the app but in fact on the system flow chart you can see its 950w (or whatever). Any ideas what we are doing wrong. I don't believe it's a wifi issue as other feeds are coming through to my app.
