Hello,
I had sent in my Multiplus II 5000/70-50 for repair but they did not find anything.
After it came back the device is behaving strange and often does not load the battery.
My setup:
The multiplus got the latest firmware version 507. It basically exists to store energy to a battery.
My venus os large installation an raspberry is on v3.20 and now on v3.21.
My battery is a 16S 280Ah system with Seplos BMS v2 10E, connected to the raspberry via RS485. Venus os detects it as SerialBattery(Seplos).
Grid meter is a 3 phase EM24 connected via RS485 to the rasberry.
Solar inverters are AC coupled and not known to the system.
I'm fetching data from Venus OS via MQTT interface.
-I tried with DVCC setting to on and off, since Seplos is not supported by Victron.
-ESS is active in mode Optimized either with or without battery life.
Inverter LEDs are of in the faulty case.
Then I get these entries in the log:
From the manual:
Voltage sense error. The voltage measured at the voltage sense connection deviates too much (more than 7V) from the voltage on the positive and negative connection of the device. There is probably a connection error. The device will remain in normal operation. NOTE: If the "inverter on" LED flashes in phase opposition, this is a VE.Bus error code (see further on).
Do I have to modify some settings? Or is the device defective and how can I make sure?
