May 21, 20242 yr Hello I am new here I want to ask if anybody know why my hybrid inverter sent about 200watts to the grid. In attachment you can see that at 12:25 about 200watts return to the grid, at 8:31 no return. when energy return to the grid i have to pay for that energy 🙂 Thanks Thanks
May 21, 20242 yr You need to show us the same graph but include your battery state of charge, it is possible your batteries was full and you were generating more PV than you where using.
May 24, 20242 yr Yes it occurs sometimes essentially in SUB mode so without battery you are in this case. Nothing to do unfortunatly, with a battery in SBU mode, you can limit this but not completly When there is more solar than needed and sudden drop of your home need, IGBT can't fit instantly and the power need to be send somewhere and the only way is the grid since in SUB all sources are connected together But @Coulomb Can explain you this better than me Edited May 24, 20242 yr by sharkut
