The system is working now for 2 months ( no problems at all) …
1h ago.. we heared a enormly load ploef …
And victron restarted …and its smells like burned electonics
But L2 does not startup
On L2 there is a PV inverter 4kw on output .. so less than the 1:1 rule.( programmed in config) , its a fronius 4k
We where doing nothing in the house .. so could not be a fault on the lines …
But now the L2 inverter does not startup anymore …
Iam off grid so no grid input ( they are working on the cable outside , to fix it ,so i can go semie offgrid)
Batteries are at 55v ( full)
When i test all my switches (230v),they are off and still nothing on the victron inverters …
When i switch on the MP2s to the front( switch) ( all 3) , than i see it startup , but 5 sec later they all tuns off again and restart … so no luck .. but i think thats the charger only modus ..
Than u get error 10 on cerbo ( system time sunc error)
On stand 1 = i get Expected devices error ..
Someone more ideas? I really think the L2 inverter has gone to heaven ..
Did you switch off your AC In BEFORE they worked on the cable outside?
The smell is of course bad …
Have you checked everything visually, contacts, fuses and cables …
Do you have an MK3 interface to hand
The best way to switch the multi-compound on and off is via the “Software” switch in the Remote Console … and then the hardware switches …
You can delete the group configuration and try to start the inverters individually … Disconnect the VE Bus connection and ALWAYS ONLY SWITCH ON INDIVIDUALLY without AC Out.
Then you can use the MK3 and VE Configure to view the system status live …
I could startup L2 inverter..
How i did it , i do not know …
So … i lett the system off for the night .
This morning , i did a firmware update and they came back alive .. dont ask how.
I redid ALL the programming in ve config. 3phase setup .
The situation NOW
The inverters discharge from batterie ,they see the grid … ( remember i was offgrid for the past 2 months with any issues)
And all my loads come from them again …
BUT NOW
When i disconnect the grid .. they go to ups mode … BUT only for about 30sec.
Than they reboot and i get on cerbo - system time sync error - and off they go again … and than on and than off again .. you get the picture …
If grid is back.. they work again like it “should be”
Gridcode is : belgium ( but i tested germany and the no grid code option doesnt work neither)
So what could be the problem now?
Ps: i still do not trust the inverters 100% after yesterday .. but they " work"
#10 Error means that there is a communication error between the components.
Check the VE bus cables between the participants and swap the order of the multis …
The only way to find out what has caused the odour is to open the covers and take an ‘odour sample’ in the device and look at the components … A FET stage may be defective or a relay may have blown …
Unfortunately, remote diagnosis is almost impossible
