This is most informative, thanks all. I've had my system installed four years ago with single Axpert 5K-48 inverter, 6 x 250W panels, and four Vision 12V 200AH batteries. The thinking was that over time batteries would become more affordable and better. Had to replace the first battery six months ago, and a second has gone now, so decided to take the plunge and rather get 3 Pylon US2000B's. Installation planned for tomorrow with help from professional, but definitely want to get the best life out of Pylons, so please help. How do I manage the 80% SOC threshold on the Pylons to ensure better life, or is this handled internally by Pylons, or a setting on Axpert? Can I connect laptop to Pylon stack to see and change parameters? Axpert prog item 2 = 25A x 3 = 75A? Use 70 or 80? Thank you Carel
