Good afternoon,
I wish people reading an happy new hear, wishing you all the best, sunny days and success in your projects.
Since 11:52 am my solar installation stopped charging my batteries.
I checked remotly my installation as I wasn't at home and I noticed the PV charger was missing on the VRM online display.
My batteries stopped charging at 11:52 exactly when the installation switched from bulk to absoprtion mode.
before I had this view :
since this morning I have that one : chargeur PV is missing
when I look the graphs : the PV yield stops at 11:51 this morning
It matches with the end of bulk step and begin of absorption step
When I came back home (at night), I noticed the bulk led of the MPPT is blinking in blue on every 4 seconds
I check the PV field fuses, I even removed them all , i tryed to re search the MPPT charge controller via multiplus interface, and restarted the software in the multiplus interface. I also removed and plugged again the ve direct cable from multiplus and from MPPt solar charger... nothing managed to find again the standard display.
Note my intallation is around 7 months old, it works fine until today while I was away from home...
I am very afraid to kill my batteries.
What do you think I can do to solve this issue?
2 months ago, I changed my internet provider box, since then I cannot manage to get Lan connection, I only managed to setup wifi connection between multiplus and internet box. When I plug the cable the IP connection is on and off every seconds (when I do ping muliplus.IP. adress -t, I get 5 times ok, then 10 times tiemout, then 1 time ok, then 5 times out... not sure there is a link but maybe the communication interface has a failure and finished its life at 11:52.
Thank you again for your support : I am looking for a solution even to protect my batteries if I need to buy a need charge controller ( how can I charge them and switch off the installation until I receive the new MPPT charger) or a better solution : manage to recover the MPPT solar charger function.
Thank you for reading,
Antoine
