I'm just wondering why you use 2 regulators? One would be enough.
Have you checked the voltage before the regulator for the turbine?
As you will know, the wind turbine generates a higher voltage the faster it spins. During the day, the
solar panel will be doing all the work and generating a higher voltage than the turbine will. In effect, the turbine is doing nothing. If you deplete your batteries then a 904 should be putting a decent charge into the batteries at full working speed.
If I were you (and you are able), cover up the
solar panel and just use the wind turbine. I would also swap the turbine to the other regulator to check whether you have a problem with the turbine regulator.
Thank you for that ,,I have done all of those things you suggest and the results are the same, as for generator speed ,your right the faster it goes the higher the output, but as stated the auto tail furle turns the turbine slightly when at full speed ( to avoid
damage,) and with this weeks gale it has been at full speed all night,..
I use two regulators so as to be able to shut down the turbine (
it has a built in facility for this) during sunny daylight hours thus using only the
solar panels, and can disconnect the panels from the batteries (
via a double pole isolator) should I wish, therefore being able to test each part of the power generation separately (
without climbing) ,showing both are working correctly.
I also fitted
one direction power diodes thinking there may be a reverse power to the solars at night , but of course the regulator all ready has this, but it was just a thought,
The system is simple and during favorable weather conditions does supply enough power for some led lighting, runs the fridge freezer during the day, and the TV and satellite in the evening,it
wont run both together for more than an hour , and three laptop and phone chargers. so on these days I use very little electricity at all, in fact the standing charge costs more per day, I use gas central heating and bottle gas for my cooking, and of course when away I use nothing, If I could stop the house rates and the standing charge I would be in front!!!! just planning a wood burner for the house ! as they say "every little helps "
