Yes. My wire runs are a bit long and I wanted to minimize further losses by using an MPPT controller and it’s was the smallest I found for the money. I may well add a second 80W panel if the one proves marginal for two house batteries and a chassis battery in the overcast Indiana climes. It was making 5.9 A today though.
