Not mixed solar

Hello guys! I have several systems for multiplus and quattro with pylontech batteries (us2000c). I have the following problem: when setting the keep batteries charged (when the batteries are 100% charged), solar energy is not mixed into the load. I use MPPT Smart Solar controllers. Please help me solve the problem. In other modes it's correct. Thanks.

If you have ESS assistant loaded select "DC-coupled PV -feed in excess" to ON.

But with this setting, excess solar energy will be fed into the grid, which I do not need.

If you set the "Maximum feed-in" to 0W or even negative number it will not feed the grid.

Just try it as a test briefly. Don't leave it on, it helps narrow down the cause.

Usually with keep batteries charged, only when the batteries are full-ish, solar would power some or all of the load, the delta coming from grid.

In your case is it all coming from grid?
