Hi everyone, I got the blue solar mppt 150/35 set up on 12v and works great but when i plug 2 batteries to pass on 24v it start blinking like "battery or pv overvoltage" from the led definition on the app victron toolkit. I don't understand why it should work up to 48v. Thx
You would need to tell the mppt you have changed the battery voltage using Victron connect and bluetooth with a VE BT dongle or a usb to ve direct cable.
Change the battery voltage and charged voltages accordingly, you can't use it without programming it to suite your batteries.
You can not simply change the batteries.
If you want to have the autodetect 12/24/48 to work, disconnect the Solarpanels, wait a minute, connect the batteries. The MPPT should now correctly detect the battery.
Now reconnect the Solarpanels.
