Re: Wind generator help request
We have an Aero6gen generator with a Flexcharge NCHC-60 controller using 2 of the LVM dump load resistors in parallel. The idea behind a dump load controller is to keep a load on the windgen while diverting overcharge current to the resistors as needed. The Flexcharge folks contend you don't need another controller as theirs does the job. We've been using the windgen for several years and have been very satisfied (except for spare parts - there are virtually none available).
If you attach the windgen to a solar-type (MPPT) controller it will simply disconnect the windgen output from the battery when the batts charge up, allowing the windgen to free-spin.
On good side is that the Aero6gen is a solid piece of machinery and will last a long time. However, you might need to replace the bearings if they feel loose or make noise.
We use both solar and wind to keep up our batteries while cruising but use a battery charger when plugged in (for AC/heat/microwave, etc.).
