[RE-wrenches] Outback VFX upgrade question

[Kirk Herander]

Hi Alan,
I have just done exactly what you plan to do, that is install blue ion batteries in an existing off grid 48 vdc System. In my opinion you really do need a mate 3S the Mate3 will work but there is potential for self-destruction. You definitely cannot use an older hub. it Has to be a 10.3 with the FXR series of inverters.
Please contact me off list for more info. I replaced the 10-year-old FX ‘s at this site with FXR’s and they are available. they are 3648’s.

I installed the VFX about ten years ago and it has worked without any issues. The client has never had a generator and has enough array to equalize his FLA batteries with array only, so has never had or needed a Mate. If I upgrade to 48V with a new inverter, it will most likely be an FXR3048. First question: Can I use an original Mate (rather than a Mate3) to set up basic programming with a R series inverter, such as charger and LBCO settings? Second: anyone have an older FX3048 or VFX3648 for sale, if the answer to the first question is no?
