I have been searching through the articles to see how best to combine solar and wind with lithium batteries.
I am providing power for a remote radio/ comm tower. The setup I have 2400 watts of solar, going into a smart solar 150/100 mppt. this charges 324 ah 48v lithium battery bank. This feeds into 3kva multiplus. I have a constant load of +- 300 watts going out the ac side. I have a BMV700 and everything is interconnected using Venus GX to make monitoring and remote configuring easier.
This all works well on 90% of the days when there is good sun, the only time I have issues is on prolonged overcast days. What i am looking at is a way of maximising the battery life by decreasing the DOD as much as possible.
The idea I have had is to install a 600 watt wind turbine and controller. I don't like the controllers as they do not seem to work well with lithium, and have rudimentary controls or setting points and from what I have read you cannot really put them through an mppt as it tracks to slow for the fluctuations of a wind turbine system.
I thought the best way to get around this is to take the controller that comes with the wind turbine and push this up to 64v and then string a number of supercapcitors with their balance boards together to make up 64vdc. then run this into an mppt on the input side. I can then monitor flow of power, and the GX / multiplus can control the system to maximise the power usage. has anyone tried this or had any luck with something similar.
