Ahoy,
fairly simple system here: 48v battery bank, isolated/no ground to chassis, Multiplus 2 GX 5k. Everything working perfectly for a year, now enhancing the system with a B2B charger from Sterling. Using a Smartshunt with ve.direct to USB cable to the MP to monitor and feed the SOC.
Shunt config is DC meter and set to solar charger. Can see the incoming wattage and Battery Meter/SOC, which is the MP, is rising aswell so i am happy from a functional standpoint.
But: Why, although i have read dozens of threads and howtos can i only use it in DC meter/Solar Charger mode and not any more senseful Shunt config/setup like DC DC Charger, Alternator etc... VRM will show the wattage then but no impact to SOC. And no, it does not matter whether i turn "has DC system" on or of within GX.
This leaves me puzzled as that "has DC system" option seemed to be crucial for most other users with 3rd party charging to a GX monitored battery bank. As i said, when set as solar charger it all works perfectly so there is no real problem - just the question, why this is not integrated better since these issues are know and discussed since 2022. I have updated the GX two weeks ago and the shunt just yesterday.
Thanks for any help and maybe this also gives assurance to anyone in a similar scenario when planning. Besides the "solar charger" glitch this is awesome and i can use VRM for SOC view.
