Multiplus2-gx + solaredge + lg-chem

Hey,

i have an installation with a 3 phase multiplus and pylontech batteries.
I want to combine this with a solaredge SH5000 + storeEdge + lg-chem + import/export meter

The current system:
grid => import/export meter solaredge => multiplus ac out + solaredge ac out => load (the house)

The basics is working, the only thing i see is that the solaredge batteries keep there charge, so the system is first draining the pylontech batteries and then the battery attached to the solaredge system. I want this the other way around, can we first drain the LG chem and then the pylontech?

The second problem, i have been trying to monitor the solaredge invertor in the gx device. According to this documentation i need to enable the sunspec on the rs485 bus. But in my setup the RS485-1 connection is used as multiple modbus connection, with 2 devices, the lg-chem and the import/export meter.
So its impossible to set this to sunspec.

You will have to set up a times discharge on the solar edge or something like that. Is there a time of use mode?

there is indeed a time-of-use

That would be the best way then.
The victron also has what is called scheduled charge where you can set whether you only want pv to run loads or pv and battery.

5

So this is basically an external controlled charge/discharge profile?

6

No its controllable from the GX for the victron system.

The solar edge one is also native.

So they will be independent of eah other, but you can set them to discharge at different times.

ok, then i can better do this externally and build the logic in home-assistant.

Probably.
