Hello again Wrenches, Some minor developments in this last week and figured I'd share my experiences so others will be prepared and not stuck in the same situation as myself. I was able to test this with a brand new out of the box Radian and another new Powerflo 16 and had the exact same outcome. A single Powerflo16 will not start a Radian. Does not matter if isolating only one of the 4 KW inverter power modules or not, it simply will not work. Midnite has been very responsive and sent me another firmware revision to test but unfortunately it did not get the results intended. However, a quick workaround that yields repeatable success for me is to have an Iota 54v 13 amp DLS converter on the bus and charging the battery before switching on the Radian breakers. This works every time and so far on both sites everything is fine once the inverter is operating. Interestingly, the Radian will boot up and operate with just the 13 amp Iota without the battery breaker even on. Till Midnite can come up with a new firmware version that does the job without an Iota I'm just leaving it on site and setting the Radian LVD at 50.8 which correlates to about 15% SOC.
I did receive a voltage vs approximate SOC chart directly from Midnite after asking about it and would seem like this would be something they intend to share but I'll let them jump in if that's what they want to do. A charger setting integration guide would be nice to have as well since the manual is still a bit light on that subject. Definitely seems like they may want to share the current status with all this since I doubt I'm the only one that's going to run into this scenario. Yes of course multiple batteries is likely the solution but in reality I'm not the only one with multiple Radian sites looking to transition from FLA to an affordable LiFePO from a trusted manufacturer like Midnite. As impressive as it is that they can offer this at nearly 20% of what a single Blue Ion was with nearly the same attributes and even more yet I still have customers that struggle to afford even one. Too much missed market potential for this not to work, I trust they will find a solution soon. Have fun out there, Nick On Sat, Nov 9, 2024 at 12:40 PM Nick Lucchese <luccheseso...@gmail.com> wrote: > Greetings Wrenches, > > Wondering if any of you have successfully paired the new Powerflo16 with a > GS8048-A yet?
