Hi I have a system with a Quattro 15k and 5kw Fronius inverter AC coupled and I am using another offgrid solar system as the AC input 1.
I am trying to ignore the AC input until the soc reaches 50% and stops the ac input when it reaches 51V.
But the issue is when the Generator ( I have put the other offgrid unit as a generator ) the fronius tries to back feed the Generator and trips it. Usually it back feeds close to 500Ws and comes back on charging the batteries and then keeps back feeding again.
Meanwhile when the AC input is ignored the frequency of quattro jumps upto 53Hz and comes back to 49Hz which affects the Fronius to trip with an AC frequency out of Range.
Please do Help me on this, I have tried everything possible
