July 5, 20224 yr I have some shading issues on my one string and have looked at optimisers for the shaded panel. My panels are 18.4A Isc, 17.2A Imp but I see Tigo only make 12A and 15A optimisers. What would be the implication of using the 15A unit on my string. Edited July 5, 20224 yr by Speedster
