My 24v 1040ah system is running with 2.6kw of solar controlled by two MPPTs in parallel, a 3kw multiplus, a Venus GX, and a BMV-712.
I am wanting to add a wind turbine to the system, and as I have a spare blue solar MPPT I was wondering if anyone has any experience with this? If I get a 48vdc turbine I think the MPPT would do the job. I was thinking if I use one of the relays in either the Venus or the BMV to switch a larger power relay to divert the turbine output from the solar controller to some dump load resistors when SOC reaches 100%, this would stop the turbine from free spinning? And also if I put the resistors in the right location I can use them for heating if required.
This would a be preferable setup for two reasons, one because I already have a spare co troller, and two because it would make tracking power generation a lot easier as I could use the Venus for it.
Would love to know everyone’s thoughts.
