I'm considering to use my 5 kW TESUP wind turbine to charge my Smart LiFe PO4 Victron's batteries. It would be much usefull to charge the batteries per night, than to have some additional 220 V electricity in the time where it is not needed.
But I'm afraid of demaging very expensive batteries by wrong charging. There is a charge controler coming with wind turbine, which I can set up to 48 V, what is the voltage of my system. (Two 24V batteries in series.) This controlor should switch off the turbine, when batteries are fully charged. But is it enough? What about charging curve? Will do the smart batteries this job or I should buy rather some additional charger controlor? I have Quatro II, which is not used for charging baterries right now. Because I'm off-grid I charge batteries only by solars MPPT controlors so far what works perfectly and during a year, we were only 3 days without electricity. But electricity demand during night will increase, so I want to be prepared.
I have read on this forum, that some dump resistors might be neccessary to protect batteries from overcharging during strong winds. There are very strong winds here and the voltage from wind turbine can be over 120 V.
Anybody has any experience with wind turbine and LiFe PO4 batteries?
