Multiplus II 24/3000 in caravan with Orion TR

A customer has the following setup:

-multiplus II 24/3000

-ccgx

-bmv 712 ve.direct connected

-smartsolar 100-30 ve.direct connected

-orion tr 24/24-17

-orion 24/12-5


so now to the problem

if in mobile use the bmv 712 is the primery battery monitor the power usage of the orions is correctly shown. But if the customer wants to use his caravan grid tied (600w solar panels) the feed in is not shown correctly. If multiplus is primary battery monitor the feed in is correct but orion tr and orion are not counted And not displayed.


is there a solution for?


best regards

Sounds like a wiring issue at the shunt. Is everything connected to the "load/charger" side of the shunt and only the battery on the battery side?

yes the shunt is installed correctly.

But the power from mppt throuh the Multiplus II into grid is not counted correctly.
