Question for the group. Grateful for some advice on mixing wind to a traditional Victron/Pylontech system. 1st time for us ! I read as many articles I could on the subject in this forum. Saw some interesting information, but still have concerns .
We have to install an off-grid system with a mix of solar and wind + generator on a remote caribbean island . System design is :
20 x 435 w panels (12 south to a 250/100) +(4 East to a 150/35) (+4 West to a 150/35)
5 Pylontech UP5000
Quattro 15Kva 48v
2 X Wind generators 2000w at 48 v . (The 2 charge controllers for the windgen have been set for Ion-Lithium batteries , at 53 v max) . These 2 wind controllers have no dump load but are "supposed" to brake the turbine as needed !
All going to a set of Lynx (Power In / Shunt / Distributor)
I am very familiar with all the solar / generator side of the system . I have never added wind , and it's a must at this location and based on the request.
I must admit I am a bit afraid to connect these 2 wind gen which I don't know to a great victron/Pylon system . I don't know enough the quality of these wind generators and their relevant charge controllers .The site is very remote . I would not want to have the windgen send too much voltage to the Pylontech , risking to have their BMS to shut down the whole system due to overvoltage .
Initially, we had designed such that the wind gen / Wind gen controllers would be connected via a DC fuse to the Lynx Power In , on the load side of the Lynx Shunt ; And treat the DC production of the wind gen as "Has DC" , expecting a negative figure.
So I am trying to find a way to "separate" as much as possible the wind part from the solar part .
I would be interested to get comments on the following option :
Send the Wind gen production to the wind controllers
Link the output of the wind controllers to the input of a new Victron MPPT charge controller , so it can be integrated to the Victron / Pylontech system via the Cerbo)
Connect the output of this Victron Charge controller to the Lynx / Shunt / batteries . Simply to have a last control via a settable Victron controller speaking to the Pylontech BMS via the Cerbo .
Does this make sense ? I am conscious of the limitation due to the start voltage of the Victron MPPT and this is a concern of course.
Would it be better to have a separate battery and a small inverter to recharge the main solar system via the AC IN 2 of the Quattro ?
I am open to all comments from members of this group who have already faced a wind integration to a Victron system. I am open to hiring any installer experienced / Knowledgeable to have an online session .
Thanks for assistance .
