Multiplus 2 GX turns off MPPT and draws power from Grid

Hi

i I have an Multiplus 2 GX 48/300 installed. Grid connected.

ESS working perfectly until:-

2wire BMS enabled ( external switched ) When activated, grid meter is ignored and Multiplus charges batteries from Grid.

at around 98%, ve-direct shuts off smart Solar, so no longer feeds back into the house.

Multiplus on 552 firmware.

tried all I can think of in veconfig and VRM settings but can’t seem to work around.

dc feed in enabled ( excess does feed in till battery hits 98% )

Any ideas?


fyi A Quattro drives the 2 wire state, depending its load.


mppt state
2 |3000
