Hey there,
I installed the most recent Venuis OS on a Pi 3 B+ and did my first steps and now...have some questions ;-)
First the setup:
- 2 Solar Panels
- SmartSolar MPPT 100/30
- BMV 712
- LifePO4 battery with JK BMS
- Inverter to generate 240VAC
- Shelly Pro 1 PM at the output of the Inverter
NO mains as it is a stand-alone system in an allotment garden.
I installed the following from github to make the Shelly work:
https://github.com/Halmand/dbus-shelly-1pm-and-pm1-Plus-pvinverter-multi-instance
I also installed the GUI mods
Currently I draw about 1300W via the Inverter (charging my car).
In the Portal I see:
The remote console shows:
I setup the "Position" of the Shelly to "1", the shelly is setup as PV Inverter.
Before that it was not visible at all.
My questions:
How can I tell the system
- that there is no mains
- that it should not add the Power of the PV Charger and the Inverter
Is it that easy that I have to setup the Shelly as "Inverter" and not as "PV Inverter" ?
What I also wonder:
In the remote console it seems as if the DC System (Charger, battery, and DC system) is completely separated from the upper part.
Another issue:
The MPPT and BMV are connected via a genuine victron cable, the JK-BMS via a simple USB/TTL converter (non isolated).
I got disconnects of the BMV and MPPT that made a restart necessary to have them visible again.
Might that be caused by the missing isolation in the BMS connection ?
Any help is highly appreciated.
Thanks in advance
S.
