Hi All. Is it possible to activate the load output only when the solar input is providing power?
asked
MPPT load output - turn on when solar is active?
@bobhof I dont have a mppt with load output so i'll let someone else comment if there's a native solution.
Thanks. I'm not very clued up with these things. I'll look into Node Red.
If it's supported natively go that route.
If not you would have a node red flow that checks solar coming in is greater than whatever value you want and if so turn on relay.
Only thing to watch out for is when youre in absorption/float as you could have 0 solar coming in but really it's available. So i would setup node red to work like this:
(if solar > x or in absorption/ or float){
// turn on relay
}
You could maybe manipulate the streetlight function and do an inverse set up, however it will use your battery a bit when it is out of peak.
Thanks for you advice @Alexandra and @matt1309. I must confess that I am a fool. I'm trying to power a small 12V fan to keep the MPPT cool when it is running but the obvious thing is to connect the fan directly to the solar input.
