As we all know, grid tied systems are supposed to export all the energy which is generated by the inverter to the grid. But with our inverter, we can make grid export as zero by restricting the generation equal to the consumption. Here we are discussing about few application about such systems.
Let’s see how the zero export functions
Here total consumption is 593W and its been served by Solar (Output Power)- 584W + Grid 9W (nominal)(fig 3)
Here Total consumption is 420W and its been served by Grid Power (208W) & Solar( Output Power 212W)(Fig 5)
Here Total Connected Load is 1200W. Even though solar can generate more power at noon, but running load is 659 W and inverter limited to the same (Fig 7)
Tip: Can add an UPS (in “AC out” Terminal of Inverter) to run critical load during power cut.
