A great project!

I think you are going to need a dump load system. If house demand is less than PV production AND if batteries are fully charged, then power must be dissipated.

Not hard to do (a big resistance coil), but I believe this may need to be incorporated in order to be code compliant.

I know of people that just use a 240 V heating element from a stove.
