[RE-wrenches] "Sharks tooth" charging profile with LG RESU battery and SolarEdge

[Howard Arey]

We have installed several LG Resu10H batteries with Solar Edge StorEdge. One
just happened to be my house.

 

I have an eGauge system ay my home so I'm seeing what others might not be
and that is an odd "sharks tooth" solar production curve.

 

These have been bluebird clear solar days in Texas but this jagged curve on
my StorEdge indicates near constant float charging of the LG battery. The
lower dasjed line is a standalone solar array that is part of my larger
system and you can see that is totally smooth.

 

My question for the group is has anyone else seen this jagged "shark tooth"
production profile when using the StorEdge / LG? Seems odd that this much
power is siphoned off constantly to keep an LG at 100% SoC.
