The ITOA controller in the FWC I believe is the one with "Built In" IQ4.
As it's time for new batteries I was considering Lithium Lifepo4
However, What I can't seem to find is if the internal IQ4 can be over-ridden by an IQ module or if I'd end up having to replace this whole unit with one that can run modules and get the IQ-Lifepo mod?
Has anyone upgrade to Lithium and know the path forward on ITOA controller?
