Hello,
I have an old Multiplus Compact 2000 1918141.
I installed the usb dongle, because I want to get some insights to help me to know how to expand the system.
The app says I must upgrade at least to 415. The inverter stops working, and I can’t control it. Disconnecting the RJ45 cable it works again.
As far as I understood, I have a small microprocessor and I cannot upgrade to 415.
So is it worth upgrading to the latest version (1918209) to get the information I want?
I don’t have an mk3 cable, so I have to find a retailer willing to lend me one, but I don’t want to take any risk if it’s useless.
Thank you!
