Hi Carl, We replaced an older set of HUPs on a quad stack of SI5048 system with the 3 cabinets of Blue Ion product about a year ago. Its working fine. The Sunny Islands SOC algorithm becomes worthless with the Blue Ion but SOC can be viewed through the eGauge interface. If you are auto starting a generator, you will want to make sure to have a voltage triggered start (not available in the Sunny Island). We have found that triggering a start based on voltage and then just holding the relay closed for a programmable amount of time is the best way to manage the generator. There is no reason to "fill" the batteries and so you can really manage the generator hours. Overall, very happy with much improved efficiency, just don't believe the Sunny Island's SOC.
Blue Ion has a good tech sheet for setting up the Sunny Island to charge them properly.
