[Martin Rusten]

hello
did anyone try this mppt wind controller out?
its suppose to be full mppt and have many adjustable parametres

but is it any good?

That controller is made for a 240V DC battery bank!?!
Very Chinese! They've been doing these high battery bank Voltages. Probably no electrical code to speak of over there.

Martin, you have a 240V battery bank?

yes im currently building a 240v battery.
need 240 or higher when the inverter is huge.

im also waiting a 3 phase 230vac 25kw transformerbased inverter the next week.
i want transformer based to get clean electricity for health benefits.

only combination i could get was with a 240v battery, ideally battery voltage should be eaven higher bechause of wire losses and transformer losses.


try to get 25kw out of a 48v battery haha its not effisient at all



i already bought 5 of the controllers i linked, some for wind and some for solar,
but after learning a little more about wind maybe this controller is crap? thats why im asking if someone else have tested this controllers?
they make those controllers for many different voltage systems

No experience with your particular controller Martin. I would be interested to hear how it all works out once you install it. Please let us know!

ok i will, but why did no one try this controllers out? they are avalible for 48v as well

i attach photo of testfitting leaf modules

I can only speculate, however, over here Chinese charge controllers, with a few (very few) exceptions, have a very poor reputation. When it comes to wind turbines and their charge controllers, usually that comes with the turbine. People rarely have to put together their own solution.
