Hi Jay, It's a recently converted to 48 from 24v system with BI Hi LFP batteries. And I'd like to see all pv's online, hence my need for an up-to-date controller(s). Old controller (it replaced a Heliotrope PWM unit, man that's taking me back) Is actually an OB MX60, but too old for a hub port. New inverter is an OB Radian 4048.
