September 13, 20214 yr Hi Guys. So I’ve recently bought myself a SunSynk inverter and a Hubble AM2. This combo works wonder! The time I designed my house and my electrical layout, I’ve already did the split on my DB having a DB for Essentials and a DB for non Essentials. I have a Prepaid Meter installed on my supply side. And I have the inverter set to supply the non essential side with my excess PV Generation. But from Time to Time I can see my inverter exports electricity past the CT clamp into my prepaid meter, causing my Prepaid meter to consume credit although the house is not consuming any electricity. This generally happens when my battery is close or on 100% soc. it doesn’t export much, but still does. Even though the inverter is set to not export, it still does. CAn this be a issue that can be resolved with a simple firmware upgrade? I haven’t done one or requested one ever since I did the installation. Regards, Jp
September 13, 20214 yr Hi JP I think anyone with a Sunsynk experiences this. However, you could try increase the minimum usage from the grid to say 50 watts - not sure of your current value? Unfortunately, if a big load is switched off and the battery is already full, it cannot react fast enough. But as you say the export should be very little. I don't believe the firmware will do anything in this regard. Thanks
September 13, 20214 yr Author Hi Branderplank. I do have a minimum use of 50w enabled on the inverter. Maybe it’s something that I should just accept and deal with it. I understand that the inverter can’t change in a matter of seconds. But sometimes it sits on export mode for up to 10 min before it adjusts

Which software and comms version do you have?

September 13, 20214 yr Author It doesn’t happen every day. Only on certain days. And never more than 2kwh sold
September 13, 20214 yr That is quite some export given that you have zero export enabled. Re the software it is not the latest but not much different than mine, I have v 3.1.6.1. Maybe a firmware upgrade will do the trick.
