I use a Multiplus 2 48/3000 with Cerbo GX and separate Li-Ion Battery, integrated via JK-BMS and control the system with Node-RED (Large OS).
While programming the control loop since 4 weeks (and optimizing) all was smooth (despite when I did wrong coding) ;-) .
However 4 days ago, out of the blue, the MP2 started to discharge the battery at full speed (as per MP2 unit config with 2.400 W). No idea why, and it took me a while to stop: Basically switched off.
In the meantime it happened 3 times again. No idea how and why, always after full charge, however not at peek, somehow delayed.
The node "Input power phase 1 (W)" "fires" the power out, I learnd to stop it by "VE Bus Reset" with "1".
I tried to implement a kind of "emergency break" using "VE.Bus Reset". Monitoring the output power and when above 2.350 W to send "1", during normal operation a "0" (as number) to "VE.Bus Reset". The result was a "not really working loop"/minutes between data flows.
Any idea why the Cerbo GX / MP2 get's the hick up ?
I use >ESS< with "Ext.Stg.", however I wonder why MP2 shows status messages "Bulk/Float".
Any idea to help circle the topic is welcome.
