Here is the thing. I have been living on my sailboat for over 30 years now, always at anchor, no marina or town quay with power. Had two 85 w solar panels, an Aerogen 4 wind generator on the yawl mast and in winter and autumn I mount a self made two bladed (1,75 m diameter) windgen on the starboard bow railing. The windgenerators had no regulation, I used them only for bulk charging the lead acid batteries. Solar was regulated by MPPT and took over the last charging.
I now decided our 40+ year old diesel was no longer wanted. Repairs without end. So I opted for electric propulsion. Bought a Lifepo4 battery and did some tests with a simple trolling motor.
Now the question. The lifepo4 battery has a much higher voltage as lead acid batteries. I measure 13, 4 volts at rest, and are charging over the old MPPT solar charger and a BMS.
Then we had a week of Meltemi, that is hard wind and I had the last day of those hard winds the Aerogen running. No regulation. In gusts the tension can go very short up to 15 volts.
Now, in the old days, my lead acid battery's had no problem absorbing that, the BMS protected the lifepo4 but the tension of the boat circuit run high. Just seconds.
Result : a varistor in my depth sounder burned out and the Dell car-air charger (12v to 19 volt) stopt working.
So I need a regulator for 12 volt Dc (I am using an Ametec motor) regulator with a dump load.
I tried a solar regulator on the Aerogen and that is no good. The regulator swishes the gen on /of in a very fast way so that the generator starts loud humming (no good no doit)
Any ideas ?
