question

Hello, If the wind generator needs to be connected directly to the battery it may be not fir to be used with the lithium/cyrix combination. Solution would be to have a (small) battery directly on the wind generator and going from there to the Cyrix-li-charge/Lithium.

Hello, for what it worth, I have a very similar setup, 2 PV connected to a BlueSolar Charger MPPT 75/15 and right behind, 8 Liontron Lithium LiFePO4 LX Smart BMS 12,8V 200Ah mounted in parallel. I also have a Venus GX and a BMV-700. Lately I decided to use different radial and axial wind turbine. The latest is an Eclectic Energy D400 wind generator connected via their 6TB regulator. Please note 6TB can handle two sets of batteries, but in my case it's connected directly to the battery side of the batteries master switch. The MPPT 75/15 is directly connected to the batteries.

I have noticed that both MPPT will turn charge into heat when they are on the same battery bank. It's more obvious with the 6TB because of the two large dump bar. The Victron MPPT 75/15 only has the back of the case to disperse heat.

I came to the conclusion none of the two controllers (6TB or 75/15) are really smart. The moment they pick another load is coming into the battery they assume the generator is on to recharge the batteries and they will disperse their own load not to fry the batteries.

I could be wrong about it but I have not read yet any sensible piece of advice about this and I would love to stand corrected if one may cast a little light on the everlasting issue of wind energy production inputed into Victron systems.
