Hi, I have an older MultiPlus Compact 12/2000 that came on my boat. I am in the process of upgrading / replacing my house batteries with LiFePo4 units, but the wiring arrangement depends on the inverter/charger capabilities.
1. I bought the Mk3-USB cable and used VictronConnect to communicate with the device. However it gives me an error that the firmware is too old. However checking the documentation, the older processor this has (number starts with 20) says that it can only output data to VictronConnect, and you can't update firmware or do anything else.
2. Is there another route to access the settings and/or configure this for LiFePo4 charging?
3. The manual says that I need VEConfigure to even change other settings, like the built in relay. How do I do this on these older devices? Do I need an old version of Windows software etc? An older connection dongle?
4. Do I need to worry? Some folks have told me that the default profiles on the Compact unit will charge LiFePo4 perfectly fine as-is. Is this something I can consider? The boat spends a lot of time plugged in, so this is the primary device charging the batteries.
Thanks!
