Hello All I will try to answer the original question then address the added concerns.
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? No the FXRs require a Mate3(s) for programming. Question Can A hub 4 be used with an FXR inverter? It depends, you can use a single FXR or paralleled inverters (120) with a HUB 4 but you cannot Series Stack (120/240) or 3phase stack (120/208) with a Hub 4 Question my suggestion here for others too. Outback still makes and sells the 3 circuit boards for the FX series of inverters (i just bought a spare set for our GVFX3648 for ~$800.00). Yes all three PCBs are available for the FX inverters. But the transformers are dedicated to the dc voltage and are not interchangeable between the 12, 24, and 48 volt inverters. The turn ratios are different. Below is a link to several whitepapers located on the OutBack Website concerning various battery chemistries . http://www.outbackpower.com/resources/documents/app-notes I hope this helps From: RE-wrenches <re-wrenches-boun...@lists.re-wrenches.org> On Behalf Of John Blittersdorf Sent: Monday, March 9, 2020 9:10 AM To: RE-wrenches <re-wrenches@lists.re-wrenches.org> Subject: Re: [RE-wrenches] Outback VFX upgrade question Todd, So is it that the control board and FET board are voltage specific, control board also grid tie or off grid specific, AC board common to all and Transformer common to all? I was unsure about the transformer as I have found most that I see with some indication of voltage written on the transformer. Probably notes to the reassembler? It makes sense that all 120vac inverters would have the same transformer. This is a good thread to clear up how simple it is to mix And match at your pleasure to make what you need from the retired FX Series inverters. I’ve been buying new boards Fron Zonna. Are there other sources?

Changing 2 of the 3 cards would make this into a 48 volt inverter. The same mate would work with this and as well as the mounts and wiring. only the batteries would need changing to 48 volts. The cost would be around $500.00.

If your customer does not need a generator, then his solar charge controller needs to be able to be set up for the lithium battery voltage settings. So the inverter simply needs to be 48 volts and has nothing to do with charging battery. You could use any 48 volt inverter and use the MATE. The inverter would only provide LBCO to protect the battery. As far as a used VFX 3648 contact me off list.

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?
