Community assistant requested.
I am looking for a assistant that will action a relay, if the Hz raises to a set figure
Ie I have a grid Tie inverter connected to the AC1 out of a multiplus 48/5000 and I am wanting to export power if my batteries are full and before the Grid tie inverter shuts down, I want to turn on AC1 In so that power is then exported. instead of being lost
I have currently got the AC1 in to be ignored and am using gen autostart to turn the AC1 on if the battery voltage drops to say 50v and off again when it raises to 53v
this works well and the AC1 in will charge the batteries if we get a cloudy day but not fill them unless the solar comes in etc
So then if the battery is full and all loads are covered then the grid tie is going to be turned off or down, I am looking for a assistant that will turn on AC1 if hz gets to say 51 hz then off again after a set time period say 1 to 6 hrs so that I can export the excess power back to the local grid.
basically I am off grid but as we are part of a community power grid it would be nice to send back unused power so that others can use it.
No point in wasting it
I tried negative battery amps in the autostart but a neg number is not allowed
even tried using quite time and setting the voltage but that wont work as well
other suggestion welcome
willing to contribute to the cost if someone can make one
Thanks
