might not track, but allows you to set the minimum input V. so the PV v won't collapse .
i plan to try one, but plan to change the input cap from 35v to 50v as i'm using 2 pv in series, and it could get up around 39v light load.
so how many watts extra could i hope for? old controller around input 26.2v charging 2 sla's 25.2v heavy load.
goal is to manually find MPP about 33-35v. near 8v more input at 4.6a. am i going to get 36 more watts? even +20 would be great! (from 2, 100w pv, now put out 60-65w each)
