At least you guys did some planning. I have a collection of solar things left over from both the 5er and TC we had, so tried to jam it all into the C. Except have had a Tracer 20 amp MPPT with no job anymore.
Have been using one 255w and its Eco-Worthy MPPT 20 amper plus three 100s in parallel with the Solar 30, and now will have another 255w to use with the Tracer so it will no longer be wasted. :)
That means three controllers instead of the two, set to the same voltage in parallel on the 450AH AGM bank. It all works for using the collection of accumulated solar things, but not how anybody would do it starting from scratch.
