New OG Project - Multiple Sources

Hi, Looking for an OG solution for remote cottage. Already have 6 x 300W solar panels in 2 banks. Was thinking of a DC system with BYD 10kW, Victron 5kW MultiPlus or Quattro, 2 x 150 x 30 MPPT. Also have the opportunity for other solar arrays, a small wind generator and a disused small waterwheel in small brook. Panels would connect via MPPTs, possibly connected via Octo GX for multiple sources? AC to the Multiplus/Quattro via existing Kipor 8kW Gen.

What is the recommended solution for small wind turbines and controlling them, and also low RPM Water-wheels? Understand there's an issue with wind via MPPT and dump loads to control speed. Any advice appreciated.

BYD

There is lots of advice out there in controlling the water wheel and wind turbine systems , you would need to get a regulator that would control these two items,

with the water wheel you may get away with a normal MPPT reg as long as the open circuit voltage of the water wheel never goes over the MPPT regs max voltage, these sorts of things are very site dependent so there is no generic advise per say
