Tom, for what it's worth---after careful review a couple of times now of the Parallax site and their line of converter-chargers (the first time was when I was trying to determine what would go in my own unit), I believe the Parallax units are good and well-designed converter-chargers for RV applications. I just don't think they should be used in a flooded-cell battery application without installing the TempAssure module. If/when the unit is left plugged in for an extended amount of time, even their low "float voltage" will eventually increase battery heat, increasing out-gassing of the electrolyte. Unless the user is monitoring battery water pretty closely, he ends up with what you experienced. While AGM-type batteries would prevent the electrolyte loss, they would certainly also benefit from the TempAssure technology which provides four different charge voltages based on battery temperature (compared to three from a multi-stage converter-charger like the Progressive Dynamics unit). I think that with the TempAssure module installed to tailor charge voltage to battery condition, the Parallax unit becomes an excellent converter-charger. I don't know why Parallax didn't just make it a standard feature on the units that can incorporate it, and bump their price accordingly.All the best, Mike
TNcanuck, I am curious what might be tripping the GFI breaker when he plugs up at home. Thank you for your explicit explanation on the electrical system as well. Since he is leaving on a trip soon, if the pedestal breaker trips, it might make for not a fun time.
Great, Tom!If you can, please provide any feedback about if/how TempAssure improves things down the road. That would be a big help in the future to others using the Parallax unit and experiencing similar problems. I know that "Jatrax" installed one not too long after he got his 2017 2552, and he said he was happy with how the converter-charger was performing afterwards, but that's the only actual feedback I've seen. Based on all I can absorb from the technical documents, however, I think it will do the job.All the best, Mike
