Hi i need to build a power system for 24v weather measuring device (wind lidar).
it consumes continuously about 110w in winter. (little less in summer, heaters are off)
It will be located in Czech republic on a fairly windy sites. So i might try to include a wind turbine. It could help down scale the solar array and battery pack. They would have to be big to reliably power my device in winter months.
On some of the sites there might be grid connection. So thats why charger is included.
I was hoping:
that someone could check my diagram for any faults. For example more fuses somewhere ?
that someone could tell me if i could benefit from including a shunt (on wind input or maybe one on the load output ? i think i don’t need it on the batt side because of the smart bms ?)
that someone could maybe tell me if they have installed a wind turbine into victron system such as this one. Im especially interested in some good MPPT. Im not sure how such device reacts if i disconnect the load&batt since i dont want to have another battery just for wind.
the batteries have a wrong pic. I need 24v, Iwill buy a correct battery(s).
Hello,
I operate two wind turbines in conjunction with Victron equipment. Please note that purchasing a wind turbine necessitates acquiring a compatible controller, specifically one that offers a 24V output. (in your case)
My turbine setup allows comprehensive turbine control via its controller, as illustrated below with the 24V controller model shown as an example.
The turbine’s output, which is 48V in my configuration, connects to a Smartshunt. The system is designed so that as power generation from the turbine increases, my MPPTs recognize this and proportionally decrease their output.
A single battery string can connect to the left side of the BMS through a Class T fuse. All chargers and loads connect to the right of the BMS. move the Lynx distributor to the right. The load can then connect to the Lynx distributor using the fuse in there. Read the Lynx BMS manual to see the correct set up.
In your set up the BMS does not protect the batteries from overcharge. The manual specifically states that you should not connect anything to the battery “upstream” of the BMS.
The Cerbo GX and BMS (due to the contactor) are likely to consume 13W on a permanent basis plus whatever 4G router / comms, perhaps another 6W, have you accounted for this.
